T3

T3 is triiodothyronine, the active thyroid hormone, supplied here as PharmaQo Labs 25mcg oral tablets, 100 per pack. It directly raises the body's metabolic rate, which increases energy expenditure and speeds up fat loss during a cutting phase. Because it is the active hormone rather than a precursor, its effects come on faster and are stronger per microgram than T4 (levothyroxine).

This is an oral tablet, so it is swallowed, not injected. A cautious approach is to start at 12.5mcg (half a tablet) once daily for the first week, then move up to 25mcg daily for weeks 2 to 4, without exceeding 50mcg per day. At the end of the cycle the dose is tapered down by 12.5mcg every 3 days rather than stopped abruptly, to let natural thyroid output recover, and the full run is usually kept to around 4 to 6 weeks.

Common effects include an increased heart rate, jitteriness or anxiety, and sweating. Running high doses or extended cycles can suppress the body's own thyroid function and, if overused, contribute to muscle wasting rather than fat loss alone. A baseline thyroid panel (TSH, free T3, free T4) before starting, a repeat check around week 3, and another 4 weeks after finishing is the standard way to keep track of how the thyroid is responding.

No. T3 is not recommended for first-time users because incorrect dosing can suppress natural thyroid output and lead to muscle loss instead of fat loss. Cardarine is generally the safer starting point for a cutting goal, and is also commonly run alongside T3 to help protect muscle mass for those who do go ahead with it.

T3 works by lifting the body's baseline metabolic rate through the thyroid, while Clenbuterol is a beta-2 agonist that drives fat burning through a different, adrenaline-like pathway. Some users combine the two, but each carries its own side effect profile: T3 affects thyroid regulation, Clenbuterol drives heart rate and tremor. They are not interchangeable, and dosing for each needs to be judged on its own rather than assumed to stack safely without monitoring.
