Our quality documentation, competitive pricing, and reliable inventory make Official Peptides the go-to source for HGH fragment research compounds.
AOD-9604 is a modified fragment of human growth hormone corresponding to amino acids 177-191, with an additional tyrosine residue at the N-terminus for stability. It is structurally related to HGH Fragment 176-191 but differs in its N-terminal modification. Preclinical research has examined AOD-9604’s lipolytic properties and its effects on fat metabolism without the growth-promoting or insulin-sensitizing effects of full-length HGH. It has been evaluated in clinical trials for obesity research. For research use only; not currently approved for clinical use in most jurisdictions.
Q: How does AOD-9604 differ from HGH Fragment 176-191?
A: AOD-9604 is similar to HGH Fragment 176-191 but includes a tyrosine residue added at the N-terminus (making it technically Tyr-hGH 177-191). This modification was intended to enhance oral bioavailability, though research has primarily examined parenteral administration. Both compounds target fat metabolism via similar mechanisms.
Q: Has AOD-9604 been studied in human clinical trials?
A: Yes. AOD-9604 progressed through Phase IIb clinical trials examining its use for obesity and metabolic disorders. While it demonstrated a strong safety profile in these trials, it did not meet primary efficacy endpoints for weight loss in the general obese population.
Q: What documentation is available for AOD-9604 purchases?
A: Every batch of AOD-9604 from Official Peptides comes with a certificate of analysis from an independent third-party laboratory confirming purity, identity, and molecular weight. COAs are available on request or included with shipment.

I’ve tried a few peptide suppliers before, but Official Peptides delivered a pretty solid experience. The AOD-9604 arrived within a few days and everything was packaged securely. I talked about it during a TikTok live and people kept asking where I ordered from. The product looked high quality and properly sealed. I liked that the website checkout process was simple and straightforward. Customer service answered my shipping question within the same day. Results felt gradual rather than dramatic, which I actually expected. Definitely a good overall experience.

I ordered AOD-9604 from Official Peptides after spending weeks comparing peptide suppliers online. Shipping was surprisingly fast and the cold-pack packaging looked professional. The vial quality and labeling gave me confidence immediately. After consistent use in my research routine, I noticed better body composition support over time. What stood out most was the clean presentation and easy ordering process. Customer support replied quickly when I asked about storage instructions. I also appreciated the tracking updates throughout delivery. Overall, one of the smoother peptide purchasing experiences I’ve had.
