Animal Model Obesity Studies Preclinical research in genetically obese rodents demonstrated more consistent effects: 50% reduction in weight gain in obese Zucker rats treated with 500 mcg/kg oral dosing for 19 days Increased lipolytic activity in adipose tissue of treated animals Upregulation of beta-3-adrenergic receptors in obese mice to levels comparable with lean controls Effects on body composition without adverse metabolic consequences Cartilage and Joint Health Research Osteoarthritis and Cartilage Regeneration Investigations in rabbit osteoarthritis models revealed potential regenerative properties beyond metabolic effects: Enhanced cartilage regeneration in collagenase-induced knee osteoarthritis models Combined AOD-9604 and hyaluronic acid injections produced superior outcomes to either treatment alone Significantly improved morphological and histopathological scores compared to saline controls Reduced lameness duration in treated animals In vitro studies showed AOD-9604 promoted: Differentiation of adipose mesenchymal stem cells into bone Increased proteoglycan and collagen production in bovine chondrocytes Enhanced myoblast differentiation, supporting potential for tissue repair Safety and Tolerability Research Human Clinical Safety Data Six randomized, double-blind, placebo-controlled trials involving approximately 900 subjects established safety profiles: No serious adverse events related to AOD-9604 administration across all studies No treatment-related withdrawals in any trial Mild, transient side effects limited to injection site reactions and occasional headaches No antibody formation detected in subjects tested for immunogenicity Metabolic Safety Parameters Critical safety monitoring revealed: No changes in IGF-1 levels at any dose or duration tested No impairment of glucose tolerance or insulin sensitivity No adverse effects on lipid profiles or cardiovascular parameters Safety profile indistinguishable from placebo in long-term studies up to 24 weeks Critical Research Limitation: Despite early promise in animal models, AOD-9604 failed to demonstrate clinically meaningful weight loss in the largest human trial when combined with diet and exercise interventions

They work differently

Amino Acids Contained Both tripeptides use histidine and lysine to bind copper, but they differ in the first amino acid in their sequence
