Cytomel T3

Cytomel T3 is a popular weight loss drug among bodybuilders that is doing wonders when it comes to fat burning and physique conditioning. Nevertheless, I strongly recommend you be careful with this compound as it is not a miracle weight loss drug that will make you lose weight and burn fat “miraculously” and it does come with risks of side effects, pretty much as any other drug out there.

  • Cytomel is the most popular brand of T3 thyroid hormone (triiodothyronine). There are numerous other brand (trade) names available too. The active substance is Liothyronine Sodium, which is the synthetic version of triiodothyronine (T3). Using Cytomel T3, you’re basically increasing your T3 levels in the body. Our bodies naturally create T3 thyroid hormones (the thyroid gland does it), but when you supplement with T3, you increase the levels exogenously (from outside sources).

Cytomel T3 (Liothyronine Sodium) is a medication that doctors prescribe to people who are suffering from thyroid hormone deficiency (hypothyroidism). When the body does not produce enough thyroid hormones on its own, naturally, to function properly, the patient is diagnosed with this condition and usually gets a prescription for thyroid hormones.

When it comes to Cytomel T3 uses in bodybuilding, there are no others except for fat burning and weight loss. That’s why it is only a physique improving drug, rather than a performance enhancer, unlike many other PEDs out there. The only performance benefit it may have is to increase your energy levels, but that’s not a real benefit. Especially in comparison to other PEDs.

What is T3?

In simple terms, T3 is the hormone in your body that is regulating how fast your metabolism is going to work. The higher your T3 level is, the higher your metabolic rate is, therefore, the more (and faster) calories you will burn. This will lead to a more fat loss potential for you.

In short, Cytomel (Liothyronine Sodium) increases T3 thyroid hormone levels and therefore your metabolism. You get the effects of more thyroid hormones and a faster metabolism.

Bodybuilders and athletes are not using it for performance enhancement purposes. Only people who want to reach a lower level of body fat would use it. It greatly speeds up the weight loss and fat burning processes. So, it would help achieve a level of body fat that would be really hard to achieve without it. It’s important to understand that T3 helps you get shredded, it doesn’t make you burn fat without a proper diet and workout plan. It just speeds it up, making the fat loss easier and faster.


  • Moreover, it’s important to understand that there’s also T4 thyroid hormone (Levothyroxine AKA L-Thyroxine) that doctors may prescribe for hypothyroidism. Nonetheless, T3 is a much more powerful hormone than T4. That’s why athletes prefer T3 rather than T4 for their physique improvement (weight loss) goals.

Cytomel T3 Dosages

As with any other PEDs out there, the ideal T3 dosage can vary a lot from one person to another. To determine the ideal dosage for you will need to take into consideration several factors. Nonetheless, unlike many other performance enhancers out there, you do not need to run a higher Cytomel dosage for weight loss and physique improvement than the standard dosage for medical purposes.

For example, the standard medical dosage is 25 mcg/day of Cytomel T3. You can achieve awesome results at this dosage. While it’s not uncommon for people to administer even higher doses for their weight loss and fat burning goals, I recommend starting with 25 mcg/day.

Anyway, those who aim for fat loss purposes usually purposely use higher amounts of T3 in order to increase the metabolic rate even more than what would be considered “normal”. That’s because this way, they are able to burn fat to a level that they otherwise wouldn’t be able to burn.


So, the dosage can go higher, usually up to about 75 mcg a day of T3 when people search to lose weight and burn fat. Although some men increase even higher, I strongly recommend against it. While you may hear of some using 100 mcg or even 125 mcg a day, that comes with high risks of side effects. Such dosages may be attempted exclusively by already huge bodybuilders who already have a lot of experience with this compound, they know what they are doing and they usually stack it with anabolic steroids.

The reason is that dosages that are higher than 50 mcg/day and especially higher than 75 mcg/day are causing your metabolism to work so fast and demand so many calories that it may put you into a catabolic state. They use steroids to avoid muscle loss. But at that point of such a high T3 level, the body is likely to demand A LOT of calories and it will not prefer stored fat over muscles – it will take its energy demands from both. That’s why by increasing the dosage you’re likely to notice muscle loss. The higher the T3 dosage you run, of course, the more muscle you are likely to lose.

That’s why the dosage of 25-75 mcg a day is going to be enough for most people to get the best benefits when it comes to fat burning and weight loss.

Cytomel T3 comes in the form of oral tablets that you need to swallow as you would swallow any other drug. While there is an injectable version of Liothyronine, it is not popular due to being much less convenient to use. Most people use it on a daily basis, every day, same time of the day, in the morning.


I would not recommend using Cytomel T3 for longer cycles than 12 weeks. In fact, that’s already an extremely long cycle. It would be much safer to use it for no longer than 8 weeks. 10-12 weeks cycles are very long, they are only for professionals who know what they are doing due to previous experience. 4-8 week cycles are enough to yield great results and are much safer. The longer the cycle length (and the higher the dosage) the more side effects can occur, of course.

That’s why it is better to take it slowly and do not abuse T3. Don’t abuse both in terms of cycle length and dosage.

Additionally, you could stack it too. People can stack it with virtually any other compound they wish. But considering that this is a drug that you use for weight loss and fat burning, they stack with other compounds for the same purposes. Some popular additions: Human Growth Hormone (HGH), Clenbuterol (Clen), cutting anabolic steroids, and others.

Whereas all of them can help you burn fat and lose weight, T3 works in very different ways than the others. That’s why they stack very well as they work in synergy to achieve your fat burning and weight loss benefits as they work in different ways to achieve the same goal.

Cytomel T3 Side Effects

As I said, the longer the cycle length and/or the higher the dosage, the more you expose yourself to side effect risks. So, once you get to a dosage of 75 mcg/day and higher or you run Cytomel for longer than 8 weeks, the side effects are likely to occur.

Remember that side effects can be noticeable at any dosage (even 25 mcg/day), but it’s pretty obvious that they are going to be more likely to occur, more frequent, and more pronounced at the higher dosage.

That’s all because you basically use thyroid hormones. The person who gets too many thyroid hormones (naturally or exogenously) will go into a hyperthyroidism state (too many thyroid hormones). As a result, the side effects are basically hyperthyroidism symptoms which usually are:

  • Tachycardia
  • Muscle loss
  • Anxiety
  • Feeling weak
  • Headaches
  • Insomnia
  • Increased body temperature
  • Increased sensitivity to heat
  • Tremors
  • Increased hunger
  • Including others

Other than that, you should be aware that as you use T3, your body stops producing it on its own. That’s a defense mechanism against too many T3 hormones. That’s why, when you stop abruptly, you may experience hypothyroidism symptoms. It is because you stop supplying your body with T3 and it doesn’t produce it anymore as the production was suppressed during the use of exogenous T3 use.

Many people use the pyramid method of administration to avoid the side effects from both abrupt stops and during the cycle.

Pyramid Method

The pyramid method of administration means that you start at a low dosage, increase the dosage if you feel you can, then decrease the dosage toward the end until you completely stop the use.

Something similar to:

  • 25 mcg/day for two weeks
  • Increase to 50 mcg/day for two more weeks (optionally, may remain on the previous dosage)
  • Increase to 75 mcg/day for two more weeks (optionally, may remain on the previous dosage)
  • If you have a lot of experience, may add 2-4 weeks here in the dosage you feel you need.
  • Decrease to 25 mcg/day for the last two weeks

Avoid Muscle Loss From T3

Remember that T3 doesn’t burn fat directly. It does so indirectly by increasing your metabolic rate. With a faster metabolism, your body demands more calories (energy) to function. That’s why it can lead to muscle loss. Obviously, the higher the dosage, the higher the metabolic rate, therefore, the more muscle loss can occur.

People who experience this issue, especially when they are using a high dosage of T3, will offset catabolism with the help of anabolic steroids assistance. The anabolic steroids will help you avoid muscle loss (maybe even help grow, depending on many factors).

That’s why bodybuilders tend to avoid the use of T3 without the use of anabolic steroids as they aim to maintain 100% of their hard earned muscle tissues. While it’s not mandatory to use anabolic steroids while using T3, it helps you maintain muscles much more and much more efficiently.

That’s why T3 often stacks with steroids, especially in men. That’s why most men who want to give T3 a try have experience with steroids first.

How Much Fat Loss Can I Expect?

I am aware that a lot of people will question this so I have to be straightforward and honest with you. T3 can be great for fat burning and weight loss, however, Cytomel T3 is NOT a magical compound that will make you shredded while you’re eating whatever you want. In fact, it’s pretty much not effective without a proper diet. Without a correct diet and workout plan, you simply do not take advantage of a better/ faster metabolism.

Please understand that it greatly helps you get to single digit body fat %, but not while you eat crap. It helps you achieve way more fat burning effects than you would naturally. And yet, it will not help you lose weight only because you’re on T3. You still need to diet hard in a calorie deficit while training hard with lots of cardio. Cytomel T3 is going to magnify the effects of dieting and working out. And the harder to diet and work out – the better the effects of Liothyronine. It speeds everything up and makes things easier, but there’s no point in it as long as you don’t diet and work out!

Does Cytomel T3 Suppress Natural Thyroid Production?

Well, unfortunately, yes, it will. By taking an exogenous thyroid hormone, it is going to stop the natural production. As said, that’s a defense mechanism of your body against hyperthyroidism.

Your thyroid gland is working because of the stimulating hormone TSH (thyroid stimulating hormone). This hormone will “indicate” your thyroid gland how much T4 it should produce. T4, as said, is a weaker thyroid hormone than T3 that is getting converted into the powerful T3 (the active form of thyroid hormone).

By using T3, your TSH goes in the toilet because the body receives signals that there’s already too much T3 in the system, so it shouldn’t produce it. While you use T3, your thyroid gland basically stops working.

Yet, the body recognizes that there is no longer the excess of T3 in the system as soon as you stop its use. That’s why the TSH is going to skyrocket again which will signal your thyroid gland to start producing a lot of T4 again, which will convert into T3.

Permanent Damage?

There are still a lot of debates about whether or not your thyroid gland can be permanently damaged from taking T3 in too high a dosage and/or for too long periods. Some suggest that if you abuse, the gland becomes accustomed and it will never produce the same levels of T4/T3 thyroid hormones again. Other studies suggest that this is just a myth and if you had a healthy thyroid before you started the use, it will eventually recover to the same healthy natural thyroid function again. In short, the post-cycle levels will always go back to the exact same pre-cycle levels, regardless if they were normal or low. But the recovery process can vary depending on the cycle length and dosage.

Anyway, there’s nothing I can say with certainty on this subject. That’s why, just to be on the safe side, I wouldn’t recommend using T3 in too high a dosage, or for too long. Unless your T3 levels were naturally low before starting the cycle and you need to use it, most likely, for your entire life to maintain normal and healthy T3 levels.

Until we can say for sure that it cannot permanently damage your thyroid gland, you better use it as wisely as possible.

Cytomel T3 is a Favorite Fat Burning Drug

While there are a lot of other fat burning and weight loss compounds, a lot of people suggest that Cytomel T3 is the product they use almost every single time they cut. While it does have some stimulating effects, it is not actually a stimulant and it works great.

Both T3 and stimulants can create cardiovascular complications when you abuse them, but T3 works in other ways (without directly working on your Central Nervous System) and remains a great fat burner.

When you use Cytomel T3 correctly, you can barely tell that you are on T3 but you lose fat and weight much faster and easier. Many people suggest they do not really get any feeling, maybe only something, yet they do notice great results. Others say that they can’t really tolerate Clenbuterol very well, but T3 does wonders for them.
