Non-peptide
Some talk
Systemic
Oral
Mitochondrial & metabolic compounds
Oral T3 thyroid hormone in contest-prep talk — not clen, not a steroid.
What people say
The thyroid pill in cut stacks — heat, heart rate, and “you will lose muscle if you push it.”Not CSA. TSH suppression and rebound talk. Not a fat-burner to leave on.
Doses people talk about
How it may feel
Sleep and hunger changes; strength drop if the dose is aggressive.
Copied prep talk25–50 mcg/day oral
Forum band. Not a protocol.
Cycles people discuss
Prep weeks, then off is the folklore. Long T3 is argued as TSH-suppressive.
Timing
Short T3 window vs T4’s long one. Felt heat is not a license.
Around the dose
With clen in old prep piles — stacked stim/thyroid is a watch-for.
Stacks
+ clenbuterol in contest folklore.
