AOD-9604 vs GLP-1 (7-37)

AOD-9604 stimulates lipolysis and inhibits lipogenesis through mechanisms believed to be independent of the insulin-like growth factor pathway. It appears to mimic the fat-metabolising action of growth hormone without triggering the proliferative effects associated with full GH or GH-releasing peptides. Oral bioavailability has been observed in some formulations, making it of interest for non-injectable protocols.

AOD-9604 is a synthetic fragment of the human growth hormone molecule, corresponding to amino acids 176–191 of the C-terminus. It is researched specifically for its lipolytic properties and is considered a lower-risk alternative to full growth hormone analogues for body composition research, given its apparent lack of effect on insulin sensitivity or IGF-1 levels.

Binds GLP-1 receptors in the pancreas, gut, and brain. Stimulates glucose-dependent insulin secretion and suppresses glucagon. Central GLP-1 receptor activation reduces food intake via hypothalamic pathways.

The active endogenous form of glucagon-like peptide-1, an incretin hormone released from intestinal L-cells after eating. The mechanistic basis for the GLP-1 receptor agonist drug class (semaglutide, liraglutide). Studied for glucose regulation and appetite suppression.
