01 — OVERVIEW
SYSTEMSHow Tesamorelin affects you

Stimulates the pituitary to release GH.

A stabilized analog of growth hormone-releasing hormone (GHRH). Binds pituitary GHRH receptors and triggers natural GH pulses, which lift IGF-1.

GH pulse
+100%
amplitude
IGF-1
+50–80%
  • Preserves the pulsatile pattern of endogenous GH release.
  • Evening dosing leverages the body's natural GH-release rhythm.
  • IGF-1 rises are typically modest and well-tolerated.

Tesamorelin triggers your pituitary gland to release growth hormone, which helps break down visceral fat — the fat stored around your organs. It's one of the few peptides with FDA approval, backed by real clinical trials for this use.
