Tesamorelin
Tesamorelin
Tesamorelin — Summary
Tesamorelin is a synthetic, 44–amino‑acid growth hormone–releasing hormone (GHRH) analogue designed to precisely increase the body’s natural growth hormone output. Its structure includes a trans‑3‑hexenoic acid group, which makes it more stable and longer‑lasting than standard GHRH peptides.
Originally FDA‑approved as Egrifta™ for treating HIV‑related visceral fat accumulation (lipodystrophy), it’s now widely recognised in metabolic health, anti‑ageing, and performance circles because it targets visceral fat specifically — the dangerous fat around organs — without reducing muscle mass.
How It Works
Tesamorelin acts on the hypothalamic–pituitary axis, binding to GHRH receptors in the pituitary.This triggers pulsatile, natural growth hormone release, maintaining normal hormonal rhythm while improving stability and duration of action.
