It's classified as a prescription-only peptide under FDA guidelines and is not approved for over-the-counter or unsupervised use
The drugpart of a class called peptideshas been around for decades
Proposed explanations include: Tissue retention of peptide or active metabolites Persistent activation of signaling cascades beyond peptide clearance Potential for active metabolites with prolonged tissue residence Excretion Pathways Limited data on elimination routes indicates: Likely renal excretion of peptide fragments based on molecular weight and water solubility Potential hepatic contribution to metabolite clearance No evidence of accumulation in chronic dosing studies in rats and monkeys Degradation products eliminated without evidence of toxic metabolite formation The dramatic disconnect between three-minute plasma half-life and prolonged metabolic effects remains one of the most intriguing and poorly understood aspects of AOD-9604 pharmacology, requiring further mechanistic investigation

Lean C57BL/6J mice and genetically obese (ob/ob) mice, all 12 weeks old, were divided into three treatment groups including: saline control, AOD9604 at a dose of 250 g/kg/day, and hGH at a dose of 1 mg/kg/day, with each group consisting of six mice
B complex vitamins typically contain 50 mcg to 500 mcg of vitamin B12 along with other B vitamins such as folic acid (vitamin B9) and pyridoxine (vitamin B6)
Animal studies from a Croatian research group attribute its effects to angiogenesis and fibroblast activity in healing tendons, ligaments, and muscle tissue, not to building new muscle protein
