T3 by Dragon Pharma
What Is T3?
T3 by Dragon Pharma contains liothyronine sodium, the synthetic form of triiodothyronine, the active thyroid hormone that controls metabolic rate. Dragon Pharma supplies it as 25 mcg tablets with 100 tablets per bottle. In a fat-loss context it is used to raise daily energy expenditure and push conditioning further than diet alone would allow.
Bodybuilders reach for T3 in the deep weeks of contest prep or an aggressive cut. The active hormone works directly on the metabolism, so the effect is stronger and faster than that of T4, which first has to be converted. That same strength is the danger: at higher doses T3 becomes catabolic, pulling at muscle tissue, and it suppresses the thyroid's own output, which is why every protocol ends with a taper rather than a hard stop.
T3 is a prescription-class thyroid hormone, and it is not a gentle fat burner. Doses are measured in micrograms, the range of real use is narrow, and heat, heart rate and energy changes are the signals that a dose is too high.
T3 Dosage
T3 reference dosing in bodybuilding is measured in micrograms per day. The common working range is 25 to 50 mcg daily, with more aggressive runs going higher and paying for it in muscle and heart load. Each Dragon Pharma tablet is 25 mcg.
| Parameter | Reference | Note |
|---|---|---|
| Starting dose | 12.5-25 mcg per day | First days to assess tolerance |
| Common range | 25-50 mcg per day | 1-2 tablets, the usual working window |
| High range | 50-75 mcg per day | Short exposure only, higher catabolic and heart risk |
| Timing | Morning | Mimics the natural morning thyroid peak |
| Cycle length | 4-8 weeks | Always ended with a taper, never a hard stop |
Cycle Length
The higher the dose, the more T3 pulls on muscle and the harder it hits the heart. Many experienced users keep it at or below 50 mcg and judge the dose by pulse, sweating and heat tolerance. Tapering down over one to two weeks at the end gives the thyroid axis time to recover.
T3 Stacks
T3 is a cutting-phase metabolic tool, and it is stacked with compounds that preserve tissue, raise endurance or add metabolic drive. All partners below are Dragon Pharma products.
| Stack partner | Role in the stack |
|---|---|
| Clenbuterol | Classic metabolic pair for an aggressive cut |
| Salbutamol | Milder beta-2 alternative to clenbuterol |
| T4 | Longer thyroid support in T3:T4 style protocols |
| Anavar 10 | Muscle preservation against T3 catabolism |
| Winstrol 50 | Hardness and dryness in deep prep weeks |
| GW 501516 | Endurance and fuel usage while calories are low |
| L-Carnitine 500 | Fat transport and energy support in the deficit |
When T3 is combined with anabolic or androgen support, the muscle-sparing side of the stack gets stronger, which is why T3 is rarely run completely alone in a serious cut.
T3 Side Effects
T3 side effects are the symptoms of running too much thyroid hormone, and they scale with dose.
- Muscle loss: the risk every bodybuilder watches for; it climbs steeply above 50 mcg.
- Heart effects: elevated pulse, palpitations and heat intolerance are dose signals.
- Nervousness and sweating: common signs of over-replacement, usually dose related.
- Thyroid suppression: exogenous T3 lowers natural thyroid output, so a taper is required.
- Appetite: can rise, which works against the cut unless calories are managed.
Women and men both tolerate T3 better at the low end of the range. The standard discipline is: low dose, morning timing, short run, and a one to two week taper at the end.
What is T3?
T3 is the short name for triiodothyronine, the active thyroid hormone, and Dragon Pharma supplies it as liothyronine sodium 25 mcg tablets. It directly controls metabolic rate.
Why do bodybuilders use T3?
Bodybuilders use T3 to raise daily calorie burn in the final weeks of a cut or contest prep. Because it is the active thyroid hormone, its effect is faster and stronger than T4.
What is the right T3 dosage?
Reference doses run from 25 to 50 mcg per day, with some aggressive protocols going higher. The starting dose is usually 12.5 to 25 mcg, taken in the morning.
Does T3 burn muscle?
At higher doses it can. Above about 50 mcg per day the catabolic pull on muscle tissue grows quickly, which is why anabolic support is stacked with T3 and doses stay controlled.
How long can you run T3?
Typical runs last 4 to 8 weeks. T3 suppresses the thyroid's own production, so the run is always ended with a one to two week taper instead of a hard stop.
What are the side effects of T3?
The main effects are elevated heart rate, palpitations, sweating, heat intolerance, nervousness and muscle catabolism at higher doses. All of them scale with how much thyroid hormone is running.
What is the difference between T3 and T4?
T3 is the active thyroid hormone that works directly on cells, while T4 is the storage hormone that the body converts into T3. That is why T3 acts faster and is dosed lower.
Can T3 be stacked with clenbuterol?
Yes, the combination is a classic aggressive cutting stack. Both raise metabolic and heart load, so heart rate monitoring is important and doses stay moderate.
How does the thyroid recover after T3?
Recovery happens through the taper at the end of the run, which lets the thyroid axis restart gradually. The longer and higher the run, the more attention recovery needs.
