Education only. Many compounds discussed are research chemicals not approved for human use in the US. This is not medical advice — consult a licensed physician.

What it is

Synthetic fragment of growth hormone (residues 176–191) modified for stability. Marketed as a fat-loss peptide; no proven body composition effect in human trials.

How it works

Theorized to stimulate lipolysis without affecting IGF-1 or blood glucose. Mechanism studies primarily in animal/in-vitro models.

What the research says

Phase 2b trial (Heffernan 2001) showed no significant weight loss vs placebo over 12 weeks. Marketing claims exceed clinical evidence.
