Summary
AHK-Cu is a copper tripeptide composed of alanine, histidine, and lysine chelated to copper. Distinct from GHK-Cu, AHK-Cu exhibits strong affinity for hair follicle receptors and demonstrates potent hair growth stimulation alongside wound healing and skin regeneration properties.
Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.
