AOD-9604 is a synthetic 16-amino acid fragment (residues 176-191) of the C-terminal domain of human growth hormone with a tyrosine substitution at the N-terminus. It selectively stimulates lipolysis by upregulating beta-3 adrenergic receptors in adipose tissue while inhibiting lipogenesis. It modulates lipid and glucose metabolism through beta-adrenergic and AMPK-related pathways without influencing IGF-1 activity, growth, or insulin sensitivity — retaining GH's fat-burning properties without its growth-promoting effects.
Standard: Research indicates 250-300 mcg daily via subcutaneous injection, administered in the morning on an empty stomach.
Maintenance: Research indicates 250 mcg daily for ongoing fat loss protocols.
Administration: subcutaneousoral
Timing: Morning administration on empty stomach, at least 30 minutes before eating. Fasted state enhances lipolytic effect.
Duration: 12-20 week cycles.
AOD-9604 completed six human clinical trials involving 900+ participants but failed to achieve statistical significance in its largest Phase IIb trial, leading to termination of pharmaceutical development in 2007. Despite this, it remains popular in the optimization community for body composition. Beta-3 adrenergic receptor knockout mice are unresponsive to AOD-9604, confirming the mechanism. It also shows promise for cartilage repair (osteoarthritis). Tirzepatide context: AOD-9604 addresses a narrower metabolic pathway than GLP-1 agonists; for comprehensive metabolic optimization, GLP-1 agonists offer stronger clinical evidence.
