TP508 was found to enhance the proliferation and differentiation of and induces chemotaxis in human osteoblasts [103, 104]
Excretion Pathways Limited data on combined excretion indicates: Primarily renal elimination of peptide fragments Hepatic metabolism contributes to overall clearance Copper recycling through normal physiological pathways No evidence of accumulation in chronic dosing studies (animal models) The relationship between rapid plasma clearance and prolonged biological effects represents a key area requiring further mechanistic investigation across all three components
GHK-Cu has something most peptides simply do not: over 40 years of continuous scientific investigation spanning cell culture studies, animal models, and human clinical trials
