AOD-9604 — Modified hGH Fragment 177-191

AOD-9604 (Advanced Obesity Drug-9604) is a synthetic 16-amino acid peptide corresponding to a modified fragment (residues 177-191) of human growth hormone (hGH). With a molecular weight of 1,815.08 Da (CAS: 221231-10-3) and the molecular formula C₇₈H₁₂₃N₂₃O₂₃S₂, this peptide contains a disulfide bond that stabilizes its tertiary structure and is critical to its characterized biological activity in research models.

Published research has demonstrated that AOD-9604 retains the lipolytic activity associated with the C-terminal fragment of hGH while lacking somatogenic (growth-promoting) properties. In-vitro studies have characterized its interactions with the beta-3 adrenergic receptor pathway and its effects on lipid metabolism in adipocyte cell culture systems. This dissociation of lipolytic and somatogenic activities has made AOD-9604 a compound of significant interest in metabolic research.

AXOM AOD-9604 is manufactured under strict cGMP-equivalent protocols and verified to ≥99% purity via reverse-phase HPLC. Each lot is accompanied by a Certificate of Analysis documenting identity, purity, peptide content, and endotoxin levels. Available in 5mg lyophilized format. For research and laboratory use only.

A new anti-obesity drug: AOD-9604 and its mechanism of action
Heffernan MA, et al. • Obesity Research, 2001

Foundational characterization of AOD-9604 as a modified hGH fragment. Demonstrates through in-vitro lipolysis assays and adipocyte cell culture models that the peptide retains lipolytic activity without stimulating IGF-1 production or exhibiting growth-promoting properties.

Reconstitution Protocol

AOD-9604 is supplied as a lyophilized powder and should be reconstituted with sterile bacteriostatic water (BAC water) for research applications.

  • Allow the vial to reach room temperature before reconstitution
  • Add bacteriostatic water slowly along the vial wall
  • Gently swirl — do not shake or vortex
  • Allow the solution to stand until fully dissolved
  • Solution should appear clear and colorless

Storage Conditions

  • Lyophilized (unopened): Store at -20°C for long-term stability. Stable at 2–8°C for up to 90 days.
  • Reconstituted: Store at 2–8°C (refrigerated). Use within 28 days of reconstitution.
  • Protect from light, moisture, and repeated freeze-thaw cycles.
  • Do not use if solution appears cloudy or contains particulate matter.

Shipping

All orders ship within the continental United States via USPS or UPS. Peptides are shipped at ambient temperature — lyophilized peptides are stable during transit. Free shipping on orders over $250.
