It was engineered to isolate and amplify the fat metabolism effects of HGH while eliminating its growth-promoting, IGF-1-raising, and insulin-disrupting properties. This targeted mechanism makes AOD-9604 arguably the lowest side-effect weight-related research compound in this catalog. Unlike GLP-1 agonists (which carry GI side effects — nausea, vomiting, diarrhea) and unlike HGH itself (which raises IGF-1, alters glucose metabolism, and carries carcinogenic risk at high doses), AOD-9604 specifically activates beta3-adrenergic receptors to stimulate lipolysis and inhibit lipogenesis in adipocytes — without touching the growth hormone receptor, IGF-1 signaling, or insulin regulation. Developed by Metabolic Pharmaceuticals Ltd, it reached Phase IIb clinical trials in obesity (META0021). Side effect profile in clinical trials was indistinguishable from placebo for most endpoints. Note: AOD-9604 and HGH Fragment 176-191 are functionally equivalent — the same peptide sequence by different naming conventions. \u003c\/p\u003e \u003cp class=\"prod-para\"\u003e This 16-amino acid fragment represents the minimal active sequence required for growth hormone's fat-burning effects, isolated from the full 191-amino acid hormone. By focusing exclusively on the lipolytic domain, AOD-9604 provides a precision tool for investigating adipocyte metabolism without the systemic effects of full-length growth hormone. The peptide functions through beta3-adrenergic receptor activation, triggering intracellular signaling cascades that enhance lipolytic enzyme activity while simultaneously suppressing lipogenic pathways. \u003c\/p\u003e \u003cp class=\"prod-para\"\u003e In research applications, AOD-9604 demonstrates selective action on adipose tissue, promoting triglyceride breakdown into free fatty acids while inhibiting new fat synthesis. The mechanism operates independently of growth hormone receptors, IGF-1 production, and insulin signaling, making it ideal for isolating lipolytic mechanisms from other endocrine pathways. Clinical trials documented an exceptional safety profile with side effects indistinguishable from placebo, reflecting the compound's targeted mechanism and lack of systemic hormonal disruption. \u003c\/p\u003e \u003cp class=\"prod-para\"\u003e The equivalence between AOD-9604 and HGH Fragment 176-191 provides researchers flexibility in nomenclature while working with the identical 16-amino acid sequence. This makes it valuable for body composition research, adipocyte biology investigation, and studies examining fat metabolism without the confounding variables of growth-promoting or glucose-modulating effects. \u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"prod-section\"\u003e \u003cdiv class=\"prod-section-label\"\u003e \u003ci class=\"ti ti-atom\"\u003e\u003c\/i\u003ePhysicochemical Data \u003c\/div\u003e \u003cdiv class=\"table-scroll\"\u003e \u003ctable class=\"prod-table\"\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003eCompound\u003c\/th\u003e \u003cth\u003eMW \/ Formula\u003c\/th\u003e \u003cth\u003eCAS No.\u003c\/th\u003e \u003cth\u003eSequence \/ Structure\u003c\/th\u003e \u003cth\u003eReceptor \/ Target\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr class=\"row-alt\"\u003e \u003ctd class=\"td-bold\"\u003eAOD-9604 (HGH Fragment 176-191)\u003c\/td\u003e \u003ctd\u003e~1817 g\/mol\u003c\/td\u003e \u003ctd\u003e221231-10-3\u003c\/td\u003e \u003ctd\u003e16-AA C-terminal HGH fragment (residues 176-191); same as HGH Frag 176-191\u003c\/td\u003e \u003ctd\u003eBeta3-adrenergic receptor agonist; lipolysis stimulator; lipogenesis inhibitor; no IGF-1 or GH receptor activity\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"General Peptide","offers":[{"title":"1 Vial","offer_id":50856856355063,"sku":null,"price":52.0,"currency_code":"USD","in_stock":true},{"title":"3 Vials","offer_id":50856856387831,"sku":null,"price":141.0,"currency_code":"USD","in_stock":true},{"title":"5 Vials","offer_id":50856856420599,"sku":null,"price":208.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/1485\/0807\/files\/Metabolic_AOD-9604.jpg?v=1781187936","url":"https:\/\/generalpeptide.com\/products\/aod-9605","provider":"General Peptide","version":"1.0","type":"link"}
