01 — OVERVIEW
SYSTEMSHow AOD-9604 affects you

Triggers fat-cell breakdown like GH.

The lipolytic C-terminal fragment of growth hormone — it mimics GH's fat-mobilizing action on adipocytes without the cartilage or anti-insulin effects.

  • Stimulates β-adrenergic receptors on fat cells.
  • Inhibits lipogenesis (new fat storage) while enhancing lipolysis.
  • No significant effect on IGF-1, insulin, or growth.

AOD-9604 is the tail-end of the growth hormone molecule — the part responsible for fat metabolism, with the rest removed. It helps break down stored fat and slows new fat from forming, without affecting blood sugar or muscle growth.

07 — CITATIONS & Q&A

Research behind the claims.

Heffernan MA, Thorburn AW, Fam BC, et al. · Endocrinology · 2001
AOD9604 reduced body fat in obese mice to the same extent as full GH, without altering glucose metabolism or IGF-1 levels.
