### Anti-Obesity Drug Fragment 9604 (AOD-9604, hGH Fragment 176-191, Tyr-hGH177-191)

- CAS: 221231-10-3
- Molecular Weight: 1817.12 g/mol
- Sequence: Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe
- Mechanism: AOD-9604 is a modified fragment of human growth hormone (hGH) spanning amino acids 176-191, with an added tyrosine at the N-terminus to enhance stability. It was developed to isolate the lipolytic (fat-burning) activity of growth hormone from its growth-promoting and diabetogenic effects. The peptid...

## Research Applications

- Weight Loss & Fat Metabolism: Known as a 'fat-burning peptide,' this modified fragment of human growth hormone stimulates metabolism and specifically targets stubborn fat without affecting blood sugar or causing cell growth.

- Insulin Sensitivity: A peptide fragment of human growth hormone designed specifically for fat loss and metabolic regulation without directly impacting blood sugar levels in research models.

- Lean Mass & Body Composition: AOD-9604 targets peripheral fat metabolism through lipolysis stimulation and lipogenesis inhibition — without appetite suppression or GH receptor binding — for clean body composition research.

- Cartilage Repair: Beyond fat metabolism, AOD-9604 has shown promising results in cartilage repair research and received FDA GRAS (Generally Recognized as Safe) status in 2014.


## Frequently Asked Questions

Q: What is AOD-9604?
A: AOD-9604 is a modified fragment (amino acids 176-191) of human growth hormone with a tyrosine addition at the N-terminus. It retains the lipolytic (fat-burning) activity of hGH while lacking its growth-promoting and diabetogenic effects. It received FDA GRAS status in 2014.

Q: How does AOD-9604 promote fat metabolism?
A: AOD-9604 stimulates beta-3 adrenergic receptor-mediated lipolysis in adipose tissue and inhibits lipogenic enzymes (fatty acid synthase, acetyl-CoA carboxylase). It does not bind the GH receptor, does not increase IGF-1, and does not affect insulin sensitivity or glucose tolerance.

Q: What makes AOD-9604 different from full growth hormone?
A: AOD-9604 isolates the lipolytic domain of hGH without its growth-promoting effects. This means no IGF-1 elevation, no insulin resistance, no cellular proliferation risk — only peripheral fat metabolism effects. It also has FDA GRAS status, indicating a favorable safety profile.
