AOD-9604 5mg · Lipolytic Fragment of hGH (176-191) · 98.8% Purity

What is AOD-9604?

AOD-9604 (Anti-Obesity Drug-9604) is a synthetic 15-amino-acid analog of the C-terminal region of human growth hormone (residues 176-191). It was engineered to retain hGH's lipolytic ('fat-mobilizing') activity while removing the growth-promoting and insulin-resistance effects of the full molecule, making it a focused tool in weight loss research.

What is AOD-9604 used for?

Most-studied applications: localized weight-loss and visceral adipose mobilization without IGF-1 elevation. Researchers also study AOD-9604 for cartilage repair (joint research), where it has shown chondroprotective effects in early animal models. Often paired with Semaglutide or Tirzepatide for compound research protocols.

How does it work?

C-terminal 15-amino-acid fragment of human growth hormone; retains hGH's lipolytic activity without its growth-promoting or diabetogenic effects. Read our complete research hub for the full literature review, or jump to our best peptides for weight loss article for comparator molecules.

Why this listing?

Unlike Semaglutide and Tirzepatide, AOD-9604 doesn't suppress appetite — it acts directly on adipocyte lipolysis. This makes it useful in research protocols where appetite preservation matters. Glow Labs' batch AOD-2604-D tested 98.8% pure.

How Peptide.best sources and verifies AOD-9604

Every AOD-9604 listing on Peptide.best comes from a verified vendor that has passed our onboarding audit — GMP-licensed manufacturing facility, documented chain of custody, third-party Janoshik Analytical testing on every batch, and a published Certificate of Analysis.

Standard research dosing

Standard research dose: 300–500 mcg subcutaneous, once daily (morning, fasted), 12-week cycles. Some protocols also use sublingual administration.

Reconstitution

This product ships as lyophilized powder. Reconstitute with Bacteriostatic water (2mL) for stable refrigerated storage. Once reconstituted, use within 30 days; keep at 2–8°C.

Protocol notes

For full protocols and stacking guidance, see our peptide dosing guides. Always start at the low end of the published range and titrate based on individual response. Half-life (~30 min (short systemic)) determines dosing frequency.

Reported side effects

Very clean profile — most-reported is transient injection-site itching. No reports of glucose intolerance or organomegaly (unlike full hGH).

Contraindications

Do not use during pregnancy or lactation. Do not combine with other peptides without reviewing pharmacology. Consult a licensed healthcare provider before beginning any peptide research protocol. Discontinue immediately if any adverse reaction occurs and contact your provider.

Drug interactions

Limited interaction data exists for most research peptides. Be especially cautious when combining with prescription medications affecting the same physiological pathway as AOD-9604 (weight loss pathway).

Certificate of Analysis

Every batch of AOD-9604 sold on Peptide.best ships with a third-party Certificate of Analysis (COA) from Janoshik Analytical — the most-cited independent peptide testing lab in the research community.
