AOD-9604
$37.72
AOD-9604 (HGH Fragment 176-191) is a synthetic peptide fragment of human growth hormone spanning residues 176-191. It retains the lipolytic properties of GH without activating the GH receptor, making it a selective tool in fat metabolism research.

Product Information
AOD-9604 | HGH Fragment 176-191 — Research Grade
AOD-9604 is a 16-amino acid peptide corresponding to residues 176-191 of human growth hormone, featuring a stabilising disulfide bridge between Cys182 and Cys189. It has received FDA GRAS (Generally Recognised As Safe) status and has been evaluated in Phase II clinical trials for obesity.
Mechanism of Action
- Beta-3 adrenergic stimulation — activates beta-3 adrenergic receptors in adipocytes, triggering lipolysis independent of GHR
- Anti-lipogenic action — inhibits acetyl-CoA carboxylase (ACC), reducing de novo lipogenesis
- No GHR/IGF-1 activation — does not bind the GH receptor or elevate insulin or IGF-1 levels
- Chondroprotective — studied in Phase IIa OA trials for cartilage repair properties
Research Areas
AOD-9604 has been studied in obesity (Phase II RCT: -1.4 kg fat mass vs +0.5 kg placebo, 12 weeks), osteoarthritis, and cartilage repair. Its separation of lipolytic from growth-promoting effects makes it a useful research tool in metabolic biology.
