GHK-Cu (glycyl-l-histidyl-l-lysine-copper) is a naturally occurring tripeptide-copper complex that plays a central role in skin remodelling, hair regeneration, and microvascular health. Endogenous levels decline by approximately 60% between ages 20 and 60.\n\nResearch from Pickart et al. (Cosmeceuticals and Active Cosmetics, 2018) documents GHK-Cu's role in upregulating collagen and elastin synthesis, improving skin firmness, and accelerating wound healing.\n\nDr. Razzak offers GHK-Cu in two protocols: topical application (compounded serum) for skin-focused outcomes, and subcutaneous injection cycles for systemic effects on micro-circulation, hair density, and tissue repair.\n\nA full topical course typically runs 12 weeks; injection cycles run 4–8 weeks with monitoring.
