Like a lot of fat burners, Cytomel is a controversial compound. One thing is for sure: T3 absolutely helps you burn fat and potentially a lot of it! The question is this: Are the negatives of Cytomel (and there are a couple of big ones) worth the results you can get? Or are you better off looking at one of the alternative fat burner options instead? Find out all this and more in my in-depth guide to Cytomel.

Let’s jump in!

What is Cytomel?

Cytomel is a synthetic version of a thyroid hormone that your body naturally produces called Triiodothyronine – commonly referred to as just T3.

Besides being vital for many bodily functions, T3 benefits bodybuilders: it can enhance fat loss.

Despite being relatively popular among some performance users, there’s still a good number of people who are rightly cautious about using T3 for fat loss. Still, I find that a lot of the fear comes from misunderstanding or even abuse of Cytomel.

History and Overview

T3 is a critical hormone that plays a role in many vital processes in our body, from the brain to the heart, digestion, and muscles. Produced in the thyroid gland, T3 is of great importance to the way our body uses energy, and this is what’s of most interest to those of us wanting to use T3 for fat loss purposes: T3 regulates your metabolic rate (the rate at which calories are utilized as energy).

The link between thyroid function and weight loss or gain is well established in the medical field, and with T3 being a primary hormone for these processes, we start to see just how powerful it can potentially be to optimize fat loss (but more on that later).

Liothyronine is primarily used to treat hypothyroidism – a condition where the thyroid gland fails to naturally produce an adequate amount of thyroid hormone (with weight gain being one consequence). Outside of its primary medical use in addressing hypothyroidism, other potential uses for Cytomel have included depression in combination with anti-depressant medications[1].

Synthetic T3 is created in the form of sodium salt, and Cytomel is the most well-known and used brand name that Pfizer owns.

Mechanism of Action

Cytomel will have the exact same mechanisms of action as the Triiodothyronine hormone your thyroid produces. The desirable benefits we’re after (fat loss as a priority usually) come with taking higher amounts of T3 than you would naturally produce.

It’s not known how many people suffer from hypothyroidism without knowing. Still, many people find after taking only low doses of T3, their metabolism is improved significantly – essentially providing a “treatment” for undiagnosed hypothyroidism.

The precise mechanism of action of thyroid hormones is still not entirely understood by scientists, but what is known is this:

  • T3 enhances how most body tissues consume oxygen.
  • It increases your basal metabolic rate.
  • T3 increases the metabolism of proteins, carbs, and fats (which also makes it catabolic).
  • Thyroid hormones are essential to almost all areas of the body but are especially important for central nervous system development.
  • Early studies show that T3 may increase brain serotonin levels (improved serotonin levels may help ward off depression).

We also know that T3 works quickly – its effects become active within just a few hours of taking a dose. Studies have shown that full effects are obtained within two to three days of starting T3[2].

Effects of Cytomel (Benefits)

The effects and benefits of the T3 hormone on the body in its naturally produced state can not be overstated: it literally is essential for nearly every bodily process. But there are, of course, specific reasons that people will look at taking Cytomel outside of a medically prescribed setting for hypothyroidism. These primarily relate to fat loss, where Cytomel is used (in the most basic sense) to increase your metabolism.

Now, as you might start to suspect if you take Cytomel when your natural T3 levels are already healthy, you run the risk of taking your levels of this hormone too high: Medically (where the thyroid gland itself was producing too much Triiodothyronine), this condition would be known as hyperthyroidism or overactive thyroid. This is why you need a good understanding of how to safely use Cytomel before jumping in!

These are the main effects and benefits of using Cytomel:

Increased Metabolism

Cytomel boosts your metabolic rate, and you will start to notice that it’s working by seeing an increase in your overall body temperature (thermogenesis). This, of course, is what leads us to the fat loss benefits of Cytomel.

Fat Loss

The main reason why Cytomel is so popular is for its fat loss effects. While it’s a direct replica of the thyroid hormone we naturally produce, not only do some people unknowingly have low T3 levels, but when you take an external synthetic T3 and increase your levels of the hormone, then the levels in circulation are going to be much higher than you could naturally produce. This substantially increases the metabolism and energy use activity of T3 – resulting in faster, more extreme fat burning.

Reduced Cholesterol

A nice bonus effect is that Cytomel reduces cholesterol levels and can do so substantially. Not only is this a valuable standalone benefit, but for those of us who use AAS or other PEDs that cause a reduction in HDL cholesterol and an increase in LDL cholesterol, T3 can potentially offset these adverse cardiovascular effects.

Synergy with Other Fat Burners

Cytomel can work in synergy with other powerful fat burners like Clenbuterol, Ephedrine, and even HGH to boost the fat loss you can achieve (but note that these combinations will also raise your risk of severe side effects).

Cytomel Dosing and Administration

Although the science says that thyroid hormones can cause catabolism at high doses, user experience with T3 has shown (through anecdotal reports) that even low doses of Cytomel can induce catabolism (loss of muscle)[3].

What causes adverse effects for you might be a lower or higher dose of T3 than what causes problems for me. This is a very good reason always to start using T3 at the lowest (beginner) dosage, regardless of how much experience you’ve ever had with any other type of PEDs.


For hypothyroidism treatment, doses typically start at 25mcg daily. With regular monitoring, patients will then gradually increase the dose by 25mcg until the proper maintenance dose is settled. This can be anywhere from 25mcg to 75mcg per day.

As performance users, we often also gradually increase the Cytomel dose as time goes on, although whether this is necessary or beneficial is controversial. Whether you follow that protocol or jump right into your targeted dosage from day one, it’s up to you. Here’s a general guide to T3 bodybuilding doses for different experience levels:


Whether you’re new to Cytomel or not, 25mcg is the sweet spot for many users. At this dosage, it’s possible to prevent catabolic muscle loss (but that’s not guaranteed), and you’re effectively only replacing what the body naturally produces – in some cases, this is actually a lower-than-natural dose.


50mcg is what I’d consider the upper limit in most cases. Few users will see any benefit in going higher than this dose, and muscle loss will become a much more serious problem at 50mcg/day. Most users will want to include an anabolic compound at this point to prevent some of the inevitable muscle loss.


75mcg is a high dose, and 100mcg is what I’d consider extreme and unnecessary for the vast majority. At this point, you’re putting yourself at much greater risk of side effects like loss of lean muscle, muscle flatness, weakness/fatigue, and anxiety. You’ll probably also have near-uncontrollable hunger 24/7, which will make dieting very challenging.


As T3 is not a sex-specific hormone, nor is it a sex hormone at all, female doses rarely need to differ from males and generally remain in the same range from 25mcg/day to 75mcg. Just like men, females will see increased side effect risks with higher doses. Dosing your Cytomel should be carefully considered, with high doses posing two main risks:

  • An increase in all side effects
  • Muscle wasting/loss

Think about it: The higher your T3 dose, the more likely you will see loss of lean muscle and the more seriously you need to think about what and how much anabolic PEDs you’ll need to include in a cycle.

Dosing Schedule, Half-life, and Cycle Length

Cytomel has a half-life of about 36 hours. Studies have shown that 95% of T3 is absorbed within 4 hours of taking your dose[4]. Taking your entire daily dose at one time is effective if done each day consistently. I like to take it on an empty stomach first thing in the morning.

This is not a long-term use compound and isn’t something you’ll want to take for months. Six weeks is a reasonable maximum length of use to balance the risks and benefits; some people will undoubtedly go for longer, but this is an individual choice based on how well you respond to and tolerate T3.

Likely Results

You will drop weight with T3, and the question is just how much weight in total and critically: how much of it will be fat? I say this because, unfortunately, you can expect to lose some lean muscle if you’re not stacking T3 with an anabolic compound to prevent catabolism and maintain muscle and strength while dieting. So when you see those pounds dropping off, you’ll want to make sure most of it is fat!

Your results can also be impacted a lot by how severe the appetite-increasing effects of T3 are for you. If you’re lucky enough only to see a minor (or even zero) increase in appetite, you’ll obviously find it easier to stick to the diet you need to be on to burn fat.

Although a few extra food calories won’t make or break your results, let me be clear on this: if you’re eating a calorie surplus every day, then you’re wasting your time using Cytomel, and results will be disappointing. With a strict diet and regular intensive cardio workouts, your fat loss with Cytomel can equal or exceed 10lbs per week.

Cytomel Cycles

I don’t recommend using Cytomel if you’re a complete beginner to PEDs in general. The side effects are too risky, and you need to couple it with at least one anabolic to minimize muscle loss – that means you’ll want to have experience with anabolic PEDs before considering T3.

For people who are at a more advanced stage of bodybuilding and, specifically, at relatively low body fat, T3 provides an additional compound in your arsenal.

Cytomel Cycle for Men

Some guys really like T3. Others swear they’ll never touch it again for one main reason: the way it causes muscle loss alongside fat loss. This isn’t such an issue unless someone is strictly focused on losing fat without concern for muscle (i.e., you’re not a bodybuilder). However, some men who notice a loss of lean muscle report that they immediately stop using Cytomel and find it’s not worth it.

Then, some guys will use T3 with anabolic steroids to help preserve muscle. Some find this works, but others are discovering that muscle loss is actually still occurring while using AAS. There are many factors that could be influencing these results, including the dose of T3 itself.

A widespread experience for men is to keep the T3 dose at 25mcg per day to minimize muscle loss. This is close to a replacement dose of your natural thyroid hormone and can help if you’re naturally not producing enough hormone but is not giving guys what we’d call extreme results.

And the other downsides?

A negative I constantly hear from men is concerned about feeling very flat on T3. Muscle flatness is a lesser talked about “side effect” of T3 and results in a weak, depleted feeling due to the highly accelerated metabolic rate.

Testosterone or Trenbolone are the two most common AAS men will take with T3. It’s well worth paying attention to the results achieved with this type of cycle: Some men have found a slight gain in muscle is possible on a moderate T3 dose stacked with Trenbolone (keeping in mind that Tren is a very harsh steroid with serious side effects of its own).

I’ve also heard of guys using pretty high doses of both Test and Tren alongside T3, thinking catabolism could be avoided but STILL seeing serious muscle flatness. Flatness is typical while you’re cutting and dieting, but Cytomel can make it quite unbearable for some of us.

When it comes to fat loss?

Much of it depends on your current body fat level and how much “easy” fat you must lose. 15lbs dropped within less than two weeks is achievable on the proper diet. I have heard of some guys finding progress stagnating after two or three weeks and side effects becoming unmanageable (sleep issues, for example).

But you know what?

If you can lose a good amount of body fat within those first few weeks, then there’s nothing wrong with stopping T3 at that point; this can be the safest and most effective way to use it.

Cytomel Cycle for Women

While thyroid hormone levels are not thought to differ much between males and females, it is known that women are more likely to have thyroid dysfunction (including hypothyroidism) compared to men.

Women who are (often unknowingly) suffering from hypothyroidism will find a dramatic improvement in overall health as well as weight loss ability when using Cytomel.

But should women be using T3 differently from men? No: for the most part, women will see the same effects as males do with Cytomel. One difference is the areas of the body where women struggle to burn fat and where T3 is able to improve fat-burning efficiency:

  • Buttocks and thighs
  • Upper arms
  • Hip area

Because women typically have a higher body fat percentage but smaller total size than men, Cytomel can sometimes be more effective for women at lower doses than it is for males; but this is VERY individual dependent, and we should not view T3 as being like anabolic steroids when comparing male and female usage.

Just like men, women are benefiting from using an anabolic alongside Cytomel, with Anavar being the AAS of choice in most cases. This is helping females preserve muscle and maintain strength to offset the catabolic effects of T3.

Cytomel vs. Other PEDs

There are a lot of fat burners being used today. Some work well, others are nearly useless, and many can be downright dangerous. So how does Cytomel stack up against some of the other most well-known and popular fat burners around today?

Cytomel vs. Clenbuterol

The most obvious comparison is to look at Cytomel alongside Clenbuterol. Clen is considered the God of fat burners due to its celebrity status.

Clenbuterol Fat Burner
Clenbuterol Fat Burner

These are two very different beasts, though. Clen is a bronchodilator used to treat asthma. It is not produced naturally in the body like T3 is. Clen exerts powerful stimulant effects, and I find it much harder to manage the associated side effects like jitters and increased heart rate. Both Cytomel and Clenbuterol will increase your metabolic rate to promote fat loss.

There are two significant factors that make Clenbuterol look like the better fat burner:

  • Clenbuterol is anti-catabolic and can actually promote some muscle gains. Cytomel is catabolic and will result in near-certain muscle loss.
  • Clenbuterol decreases your appetite, while Cytomel increases your appetite.

Clenbuterol has more worrying and potentially severe side effects than Cytomel. Some people can handle it, others can’t. Clen is the better choice for fat burning because of the two points noted above, but only if you can cope with running such a powerful stimulant.

Cytomel vs. DNP (Dinitrophenol)

DNP is often talked about in performance circles, yet it does not have the more mainstream popularity of Clen or Cytomel.

DNP Fat Burner
DNP Fat Burner

Just like Cytomel, DNP will also increase your body temperature and cause increased sweating. It’s annoying, but that’s how you know they’re working. More importantly, many DNP users see a decrease in strength and an increase in lethargy, more so than with T3. This is primarily a result of just how fast and how much your body is burning fat.

DNP can burn an impressive amount of fat – think 1-2 pounds or more each day. Both DNP and Cytomel can cause muscle loss. Both will have you feeling flat, and both can increase your appetite.

DNP is the riskier drug, in my opinion. Too high of a dose can cause serious health problems (like cataracts) and even death. And it’s a compound I’d use for no more than two weeks. On the other hand, Cytomel can be used relatively confidently for six weeks or a little longer. I wouldn’t recommend DNP to anyone but the most advanced user because of the very high risks involved.

Stacking Cytomel

It’s perfectly fine to use Cytomel on its own in a cycle, but you need to prepare for possible muscle loss. And that catabolic activity leads both guys and girls to start Cytomel with one or more anabolic agents. Most commonly, this will be an AAS or two or sometimes HGH. These will help preserve muscle while reducing your body fat and insert a host of other benefits according to the steroid used.

Cytomel + Testosterone (Cutting Stack)

It is a simple but effective cycle for males that uses testosterone to offset the catabolic effects of Cytomel and potentially build some muscle as well.


  • Fat loss
  • Muscle and strength preservation
  • Cholesterol support
  • Possible muscle gains
  • Faster recovery
  • Improved mood and libido
  • Vascularity


  • Cytomel: 50mcg/day
  • Testosterone prop: 400mg/week
  • Cycle length: 6-8 weeks

Possible side effects

  • Increased appetite
  • Testosterone suppression
  • Hair loss
  • Increased blood pressure
  • Anxiety
  • Excess sweating and body temperature
  • Acne
  • Water retention


While this is a cutting cycle, your diet will need to shape this cycle. Running a calorie-deficit diet while using testosterone is going to allow better maintenance of strength and muscle compared to using T3 alone. You’ll be able to perform better in the gym with less lethargy, and fat-burning results could exceed 20 lbs over six weeks.


Enclomiphene for four weeks: 25mg/day for the first three weeks, then 12.5mg/day for the final week.

Cytomel + Anavar (Cutting Stack)

This stack is useful for males and females, with Anavar being used both as an anti-catabolic and increasing leanness, muscle hardness, and vascularity. Males who run this cycle need to include a testosterone base (not necessary for women).


  • Increased fat loss
  • Muscle hardness
  • Dry, lean, and vascular physique
  • Cholesterol support
  • Muscle and strength preservation


  • Cytomel: 50mcg/day
  • Anavar: 50mg/day
  • Testosterone: 200mg/week
  • Cycle length: 6-8 weeks

Possible side effects

  • Some muscle loss
  • Increased appetite
  • Hair loss
  • Increased blood pressure
  • Anxiety
  • Excess sweating and body temperature
  • Testosterone suppression


Anavar is going to take fat loss to another level here and take you into shredded contest territory. Without any water retention to worry about, your increasingly lean physique will be dry and vascular. If you’re already very lean before starting this stack, you will find it effective for breaking through to those very low levels of body fat. Anavar will also help reverse muscle flatness and give you back some excellent pumps in the gym.


Enclomiphene 25mg/day for the first three weeks and 12.5mg/day for the final week.

Cytomel + Trenbolone + Testosterone (Recomp Stack)

This is a hardcore stack with the inclusion of Trenbolone, which is a steroid for advanced users only. I call this a recomp stack rather than pure cutting because Tren delivers all-over aesthetic benefits. Many users also find T3 reduces or eliminates the insomnia caused by Trenbolone. Both Tren and T3 increase body temperature and will directly facilitate fat loss. I would run this stack for eight weeks maximum.


  • Fat loss
  • Muscle gain and preservation
  • Increased strength
  • Enhanced vascularity and dryness
  • Fast recovery
  • Increased confidence and libido


I recommend adjusting your Trenbolone dose according to your comfort level with that AAS. Below is a basic recommendation:

  • Trenbolone: 300mg/week
  • Testosterone: 200mg/week
  • Cytomel: 50mcg/day

Possible side effects

  • Increased appetite
  • Hair loss
  • Increased blood pressure
  • Anxiety
  • Excess sweating and body temperature
  • Testosterone shutdown
  • Liver toxicity
  • Gynecomastia
  • Paranoia
  • Insomnia


Trenbolone is a brilliant recomp AAS, so coupled with Cytomel, you will see an impressive increase in fat loss, along with leanness, physique hardness, and vascularity. Tren is a powerful ant-catabolic and can completely offset the catabolic effects of Cytomel as well as potentially have you gaining some lean muscle while burning fat at the same time.


With Trenbolone metabolites able to stay in your system for months, and sometimes years after use, it’s unlikely that PCT will restore regular testosterone function. Instead, testosterone cruising or TRT is strongly recommended.

Cytomel PCT

Any male who has used anabolic steroids will be familiar with testosterone shutdown and the need for PCT. It’s a common mistake to assume that by using exogenous thyroid hormone in the form of Cytomel, your natural thyroid hormone production will “shut down.” However, T3 is an entirely different hormone type to testosterone, and the good news is that we don’t need any PCT after using Cytomel.

What is essential to do is this: Taper down your Cytomel dose to come off the hormone with minimal side effects. Usually, this is a week or a little more at 25mcg daily before stopping use. If you suddenly stop using Cytomel, you will feel very fatigued, your metabolism can slow right down, and you can fall into a state of hypothyroidism (and start gaining weight again).

So, while this is definitely not a form of PCT, the dose tapering of Cytomel is recommended and acts as an effective method of restoring your regular thyroid function and, importantly, helping you avoid feeling absolutely horrible for those first few weeks after stopping Cytomel.

Cytomel Side Effects

Cytomel is considered an advanced and potentially dangerous PED choice. It comes with actual health risks if not used carefully. Here are the main side effects you need to watch out for when using Cytomel:

Muscle Loss

While it’s easy to get excited about Cytomel’s excellent fat-burning effects, this can come at the expense of your existing lean muscle because T3 can be catabolic. It will use both muscle AND fat for energy expenditure. Therefore, it provides no anabolic effect whatsoever. Suppose you are concerned about muscle loss while using Cytomel. In that case, you’ll undoubtedly need to use an anabolic PED alongside T3 – whether an AAS or a suitable SARM, HGH, or other compound.

Sweating and Higher Body Temperature

An increase in body temperature (one or two degrees above normal) is a natural consequence of Cytomel ramping up your metabolic rate. In fact, this is the very side effect that will be letting you know that Cytomel is doing its job!

You should be worried if you don’t experience a higher body temperature shortly after starting T3; it can indicate a dose that’s too low or a poor-quality product. There’s not a lot you can do to relieve this side effect besides reducing your exposure to hot environments, and you can also expect an increase in sweating to come along with it.


Because Cytomel has some stimulant-like effects, it can cause some people to notice an increase in anxiety-type feelings. A jittery feeling can sometimes accompany the anxiety. Although it’s unlikely to be as severe as with something like Clenbuterol, if you suffer from anxiety, symptoms may worsen when using Cytomel.

Blood pressure

Despite its positive effects on cholesterol, Cytomel can also negatively impact your cardiovascular system. This includes an increase in your heart rate, irregular heartbeat, and increased blood pressure. Short-term use should prevent any damage, but longer-term use or higher dose use does put you at risk of more serious cardiovascular health problems. This is the top reason I recommend limiting T3 use to no more than eight weeks at a time.

Increased Appetite

When you’re trying to burn fat, the last thing you obviously want is a boost to your appetite, but T3 can cause increased hunger. Some users won’t feel it at all, others will have a mild appetite increase, and some find it a more difficult-to-control problem. The appetite change will often come within the first hour of taking your dose, and doses of 50mcg or more tend to worsen this problem.

Hair Loss

Temporary hair loss is possible during the first few weeks or even months of using T3. This seems to be a rare side effect, and most people won’t suffer from it, but I’ve certainly read a number of T3 users complain about hair shedding. This is NOT the exact cause of hair loss as AAS-related male pattern baldness, and in almost all cases, your hair will actually regrow on its own over time.


With T3 not being a sex-specific hormone, females can expect the same side effect risks as male users of Cytomel.

Where to Buy Cytomel?

Cytomel T3 is still used for medical purposes and is produced pharmaceutically. Currently, the Cytomel brand is owned by Pfizer, and if you can obtain genuine Cytomel tablets, you’ll obviously be getting the best quality and purity.

Not all of us can access pharma-grade Cytomel, though, which leaves the option of purchasing it on the black market or in liquid or powder form from research chemical suppliers.

Availability of Cytomel

Pfizer’s pharmaceutical Cytomel brand contains the active ingredient liothyronine, and the tablets are sold in three different doses: 5 mcg, 25 mcg, and 50 mcg.

In some countries, generic forms of this hormone may be sold on the pharmaceutical market. Typically, these will be labeled as Liothyronine and are identical to the brand name Cytomel in all but their labeling. Counterfeiting of T3 is not known to be an issue either.

Research chemical T3 in liquid or powder form will rarely be as potent or pure as genuine pharma-grade tablets.

Underdosing can be a problem, and it will soon become evident that you’ve got an underdosed product if you can take 50mcg (or more) and see no muscle flatness or feel noticeably warmer (higher body temp). In those cases, I suggest not increasing your dose to get the desired effects – instead, find yourself a better research chemical lab supplier.

And here’s something else you should know:

An injectable form of liothyronine sodium called Triostat is also sold pharmaceutically, but this is only for use in medical emergencies, and under no circumstance should we attempt to use this injectable form of T3.

Cytomel/T3 and other thyroid hormones like T4 are not placed in the same class as anabolic steroids because they are very different types of hormones. Unlike anabolic steroids and other performance-enhancing drugs, there is currently no ban or prohibition of the use of T3/Cytomel by athletes.

There’s long been a debate about whether the use or abuse of T3 should be considered for a ban. Still, the difficulty in banning a hormone that naturally occurs in the body at varying levels between individuals and the fact that it is used as a medication to treat legitimate medical conditions makes this a complicated issue.

This means that the World Anti-Doping Agency (WADA) has not banned it because they have not found that T3 is effective as a performance-enhancing substance. In fact, WADA’s current position is that thyroid hormone could even be detrimental to athletic performance[5]!

But what about when it comes to you wanting to use Cytomel for personal use? In most countries, Cytomel is legal to use with a valid doctor’s prescription to treat hypothyroidism. Even though Cytomel isn’t listed as a controlled substance in the US, it’s still legal to purchase with a prescription.

Besides official pharmaceutical tablets, some research labs also sell a liquid form, which you can technically purchase legally for the purposes of research only. No prescription or any evidence is required to buy Cytomel from research chemical suppliers.

Typical Pricing

With Cytomel being prescribed as a hypothyroid medication in many countries under different brand names (as well as generics), the cost of buying it legally with a prescription will differ wildly depending on your location and what kind of insurance or government assistance you can access.

  • In the US, generic liothyronine sodium can be found for around $75 for 90x5mcg tablets.
  • For the genuine Cytomel brand, you could be looking at over $200 for the same product.

But that assumes you have a prescription and buy your T3 from genuine pharmaceutical suppliers. Without that, you will be looking at black market purchases. With this being a regularly used compound by performance users, most of the reputable anabolic steroid suppliers will also be selling T3. Some even sell the Cytomel brand, while others will have imported or generic versions.

I have seen generic 25mcg liothyronine sodium being sold for over $55 for just 30 capsules, so while you often won’t save money by purchasing black-market T3, it’s the only other option available outside of liquid or powder research chemicals. Research chemical sourced T3 is typically much cheaper but less convenient to administer and certainly less reliable in terms of quality control.

Final Thoughts

Cytomel is more powerful than you’d expect a naturally occurring thyroid hormone to be, but unfortunately, this power cuts both ways. No doubt it can move some fat and move it pretty quickly. If you’re looking for one of the more extreme methods of getting rid of stubborn body fat, then T3 is a potent choice.

You wouldn’t think a naturally occurring hormone could pose such a high risk of side effects, especially when we think about how relatively safe it is to use even high doses of testosterone. But with T3, it all comes down to how much you’re taking and for how long. The big mistake is to think using T3 is like using testosterone. They are NOTHING alike!

My view is this:

I don’t like how catabolic Cytomel is. Losing muscle while dropping fat is really tough to handle if you’ve been working hard for years to bulk up.

For those who ONLY concern themself with fat loss with little regard for short-term catabolism? I’d take Cytomel over Clenbuterol, for example, because the stimulant effects of Clen are hardcore (among other reasons).

You might be the opposite: you might respond better to Clen than to Cytomel. Some people even use both together. But I’d only use Cytomel when running a powerful anabolic with it and when I want to run a short, sharp cut for a few weeks, but not for much longer than that.
