AOD-9604

Also known as: Anti-Obesity Drug 9604, Tyr-hGH Fragment 177-191

A modified fragment of human growth hormone studied for fat metabolism without growth-promoting effects.

Overview

AOD-9604 is a synthetic peptide fragment corresponding to the C-terminus of human growth hormone (amino acids 177-191) with an added tyrosine at the N-terminus. It was developed to isolate the lipolytic (fat-burning) properties of HGH without its growth-promoting or diabetogenic effects.

Mechanism of Action

AOD-9604 mimics the lipolytic fragment of HGH, stimulating lipolysis and inhibiting lipogenesis. It acts on beta-3 adrenergic receptors in adipose tissue, enhancing fat oxidation without affecting blood glucose or IGF-1 levels.

Pharmacokinetics

Rapid absorption following subcutaneous injection with peak levels within 15-30 minutes. Short half-life of approximately 30-60 minutes.

Stacking Recommendations

Peptides that may be combined based on complementary mechanisms in research settings.

Rationale: Enhanced fat loss

Synergy: GH release combined with direct lipolytic action

Rationale: Body composition

Synergy: Complements AOD lipoly with GH pulse
