What is CYTOMED 25 (Liothyronine Sodium T3)?
CYTOMED 25 is T3, the active thyroid hormone. It is the strongest non-stimulant fat loss tool here, and it takes muscle along with the fat if you let it.
Also sold as Cytomel, Triostat, Tertroxin or liothyronine sodium.
Liothyronine is T3, the active thyroid hormone. Your thyroid mostly produces T4 and your body converts it to T3 as needed, so taking T3 directly skips that step and works immediately. It raises the rate at which you burn through everything, which is why it works and also why it is not selective about what it burns. Read our full T3 overview.
CYTOMED 25 benefits
- Raises metabolic rate directly, without waiting for conversion from T4
- Works immediately rather than building over weeks the way T4 does
- The strongest non-stimulant fat loss tool here, with no jitters and no effect on sleep
- Commonly run alongside anabolics, which is what keeps the muscle loss in check
- 25mcg tablets, which is the standard starting dose and a clean step size
CYTOMED 25 dosage
- Starting dose
- 25mcg per day for the first week
- Common range
- 50 to 75mcg per day
- Ceiling
- 100mcg per day, experienced only
- Ramp
- Increase by 25mcg every 5 to 7 days

Ramp up and ramp down. The dose ladder is the protocol, not a suggestion, and both ends of it matter.
Run it with anabolics and keep protein high. T3 on its own in a hard deficit costs lean tissue, and that is the most common way this compound disappoints people.

Who is CYTOMED 25 for?
People already in a deficit who are running anabolics alongside and want the last of the fat to move faster. It is a finisher rather than a starting point.
It is the wrong purchase for anyone dieting without anabolic support, and for anyone who wants something they can simply stop when they are done. Astera Labs sells the same 25mcg in a sachet.
How to use CYTOMED 25
Swallow with water, once daily in the morning. Take it at the same time each day and step the dose up and down rather than jumping.
Frequently asked questions
Is this dosed in micrograms or milligrams?
Micrograms, and the distinction matters more here than almost anywhere else in the catalogue. A tablet contains 25 or 50 millionths of a gram.
Reading mcg as mg would mean a thousandfold overdose. Thyroid hormone is one of the few things here where that mistake would land you in hospital, so check the unit on the box.
Will it burn muscle as well as fat?
Yes, and this is the thing to plan around rather than hope about. T3 accelerates the breakdown of tissue generally, and lean mass is not exempt.
Running it alongside anabolics, keeping protein high and not stacking it on top of an already severe deficit are what keep that in check. On its own in a hard cut it will cost you muscle.
Why can I not just stop taking it?
Because your own thyroid has been producing less while you supplied the hormone. Stop suddenly and you have no external supply and a downregulated gland at the same time.
The result is a few weeks of feeling cold, flat and exhausted, with fat loss reversing. Tapering down over a fortnight lets your own production come back up as the dose falls.
T3 or T4 for fat loss?
T3, clearly, if fat loss is the goal. It is the active hormone and it works directly.
T4 has to be converted, and in someone with a normally functioning thyroid the body simply adjusts how much it converts. That is why T4 is a treatment for an underactive thyroid rather than a fat loss tool.
Does it need PCT?
No. Thyroid hormone is not an anabolic steroid and it does not suppress testosterone, so there is nothing for a SERM to do.
What it does suppress is your own thyroid output, and the answer to that is tapering rather than a post-cycle protocol.
