AOD-9604
A peptide fragment (176-191) of human growth hormone that specifically stimulates lipolysis.
Medically reviewed by Dr. Jonathan Snipes, MD. Last reviewed May 6, 2026.What It Is
AOD-9604 is a modified amino acid fragment of hGH. Unlike full growth hormone, it specifically targets fat breakdown without affecting blood sugar or growth.
How It Works
It stimulates the pituitary gland to speed up fat metabolism and inhibits lipogenesis (fat production). It does this without the broad effects of full HGH.
Who It's For
Those looking for targeted fat loss support without the systemic effects of growth hormone peptides. Works well as part of a comprehensive weight management protocol.
Who Should Avoid It
Generally well-tolerated. Avoid during pregnancy.

Common questions about AOD-9604
- What is AOD-9604 and what does it do?
- AOD-9604 is a synthetic 16-amino acid fragment of human growth hormone (residues 177 to 191) developed in the 1990s to retain the lipolytic (fat-burning) properties of growth hormone without the growth-stimulating or insulin-resistance effects. The peptide promotes lipolysis (fat breakdown) and inhibits lipogenesis (new fat formation) without affecting blood glucose or IGF-1.
- Does AOD-9604 actually help with fat loss?
- Animal studies and small human trials support AOD-9604's lipolytic effect. A 12-week 2007 trial showed modest weight loss (~3 percent versus placebo) in obese adults. The peptide is more often used as an adjunct to GLP-1s (tirzepatide or semaglutide) or as a stand-alone for patients who do not tolerate GLP-1 GI side effects. Effects are gradual and require consistent dosing for 8 to 12 weeks.
- How is AOD-9604 dosed?
- Standard subcutaneous protocols deliver 250 to 500 mcg per day, dosed once or twice daily on an empty stomach (food blunts the lipolytic effect). Optimal Balance Pharmacy compounds AOD-9604 against PeptideRx prescriptions; your provider sets the dose based on your goals. Most protocols run 8 to 12 weeks at a time.
- Where and how do I inject AOD-9604?
- Subcutaneous injection into the abdomen for systemic effect or directly over the area you want to target for localized lipolysis. Use a 31-gauge, 5/16-inch (8 mm) needle on a U-100 insulin syringe. Inject in the morning on an empty stomach for best lipolytic effect, ideally 30 to 60 minutes before fasted cardio if cardio is part of your protocol.
- How is AOD-9604 supplied?
- Compounded by Optimal Balance Pharmacy under a 503A patient-specific prescription. Ships pre-reconstituted and ready to inject. Every batch is tested by Eagle Analytical Services for sterility (ScanRDI or Celsis) and bacterial endotoxin (USP <85>); the Certificate of Analysis is published on this product page.
