AOD9604

Well Studied

Modified hGH C-terminal fragment

AOD9604 is a synthetic peptide fragment derived from the C-terminal region of human growth hormone (amino acids 177-191). It has been studied in metabolic research for its effects on lipolysis and fat metabolism pathways, independent of IGF-1 stimulation. Published research has investigated its interaction with the growth hormone receptor and its metabolic effects in laboratory models. RaysunPeptide supplies AOD9604 for qualified research and laboratory applications.

Mechanism of Action

Stimulates lipolysis and inhibits lipogenesis through beta-3 adrenergic receptor upregulation, without binding to the GH receptor. Does not affect glucose metabolism or increase IGF-1 levels.

Key Benefits

1Targets fat loss through selective lipolysis
2Avoids growth hormone side effects
3No effect on blood glucose or insulin
4Does not increase IGF-1 levels
5Metabolically safer than full hGH
6Emerging cartilage repair potential

FAQs

Does AOD-9604 cause blood sugar problems like full human growth hormone?

No. AOD-9604 is a modified hGH fragment that stimulates lipolysis without binding to the GH receptor or affecting glucose metabolism. Unlike full GH which causes hyperglycemia and insulin resistance, AOD-9604 does not increase IGF-1 levels or disrupt glucose homeostasis, making it metabolically safer.

How quickly will I see fat loss with AOD-9604?

Week 1-2 shows minimal noticeable effects as compound accumulates. Week 3-4 brings subtle body composition changes. Week 5-8 produces more noticeable fat loss especially with diet and exercise. Week 8-12 shows continued fat reduction and improved body composition. Total timeline is slower than GLP-1 agonists.

Can AOD-9604 be stacked with semaglutide or other weight loss peptides?

Yes. AOD-9604's lipolytic mechanism complements semaglutide's appetite suppression through completely different pathways. However, combination data is limited. Both are safe separately; combining requires monitoring for additive dehydration/GI effects common with semaglutide.

Is there any cartilage repair evidence for AOD-9604 in humans?

Animal studies show AOD-9604 combined with hyaluronic acid enhanced cartilage regeneration in osteoarthritis models. However, this is preclinical; human cartilage repair data doesn't exist. Joint health claims should be considered theoretical unless based on clinical trial data.
