About AOD)
AOD-9604 — also known as hGH fragment 176–191 (CAS 221231-10-3) — is a synthetic 16-amino acid peptide corresponding to the C-terminal lipolytic domain of human growth hormone. It is supplied as a laboratory-grade lyophilized powder intended strictly for analytical and non-clinical research applications.
Unlike full-length hGH, AOD-9604 retains the lipolytic signaling domain (residues 176–191) without engaging the IGF-1 or insulin receptor pathways, making it a clean tool compound for isolating fat metabolism signaling in adipocyte models. Researchers use AOD-9604 in 3T3-L1 and primary adipocyte cell systems to study β3-adrenergic receptor activation, hormone-sensitive lipase (HSL) pathway modulation, and lipolysis-related gene expression under controlled laboratory conditions.
COMMON RESEARCH APPLICATIONS
Adipocyte Lipolysis Models
AOD-9604 is used in 3T3-L1 adipocyte differentiation and lipolysis assays to study β3-adrenergic receptor activation, HSL phosphorylation, and free fatty acid / glycerol release as quantifiable pathway endpoints.Fat Metabolism Pathway Screening
Examined in metabolic gene expression panels (ATGL, HSL, perilipin) across adipocyte and pre-adipocyte models to characterize lipolysis pathway selectivity relative to full-length hGH and β3-agonist reference compounds.IGF-1–Independent GH Signaling Research
Used to delineate IGF-1-independent versus IGF-1-dependent growth hormone effects. AOD-9604 does not engage GHR/JAK2/STAT5 signaling, making it a useful negative control in GHR pathway studies.Comparative Peptide Fragment Studies
Benchmarked alongside AOD-9604 + L-Carnitine blends and other lipolytic peptide fragments to evaluate additive or complementary effects on mitochondrial fatty acid transport and energy substrate utilization. -

What is this product?
AOD-9604 (CAS 221231-10-3, MW 1815.08 g/mol) is a synthetic 16-amino acid peptide — the C-terminal fragment (residues 176–191) of human growth hormone — supplied as a lyophilized powder for laboratory research use only. Also known as hGH fragment 176–191 or Anti-Obesity Drug 9604.
-
What purity and testing methods are used?
Each lot is tested by reverse-phase HPLC and MS confirmation to ≥98% purity with sequence verification. A lot-specific COA is included with every order, accessible via QR code on the label.
-
What are the key chemical identifiers?
CAS 221231-10-3 · Molecular formula C₇₈H₁₂₃N₂₃O₂₃S₂ · MW 1815.08 g/mol · Synonyms: AOD9604, hGH fragment 176–191, Anti-Obesity Drug 9604.
-
What signaling pathways does AOD-9604 address in research models?
AOD-9604 is studied in lipolysis and adipocyte biology models including β3-adrenergic receptor activation, hormone-sensitive lipase (HSL) phosphorylation, and ATGL/perilipin pathway research. Notably, it does not engage the IGF-1 or JAK2/STAT5 signalling axes, making it selective for the lipolytic hGH domain.
-
How is AOD-9604 reconstituted for research use?
Dissolve in sterile water or PBS (pH 7.4) at ~2 mg/mL. Use immediately or aliquot and store at −80°C to prevent degradation. Avoid repeated freeze-thaw cycles. Protect from light.
-
What is the recommended storage upon receipt?
Store immediately at −20°C desiccated. For long-term stability, −80°C is preferred. Short-term at 2–8°C is acceptable for up to 2 weeks. Inspect vials for integrity upon receipt.
-
What is a COA and why does it matter?
A COA documents lot-specific purity (HPLC ≥98%), sequence verification (MS), and appearance. Each lot ships with a QR-accessible COA. Review before use to confirm identity and purity meet your experimental requirements.
