GHK-Cu is one of the most studied peptides for skin rejuvenation and anti-aging. Naturally present in the body, its levels drop sharply after 30 — boosting collagen, speeding up wound healing, and supporting hair growth. Ready to use, no reconstitution needed.
GHK-Cu is a naturally occurring copper peptide found in human plasma. Levels are high in your twenties — around 200 ng/mL — and decline to half that by age 60. This age-related drop has made GHK-Cu one of the most researched compounds in regenerative biology, with an unusually broad range of studied effects for such a small molecule.
The most documented effects are on collagen and elastin synthesis. GHK-Cu activates fibroblasts — the cells that produce the structural proteins keeping skin firm and elastic. Studies show significant upregulation of collagen production, improved skin thickness, and accelerated wound closure. Its gene-regulatory activity spans over 4,000 genes involved in tissue remodelling and inflammation resolution.
Beyond skin, GHK-Cu has been extensively studied for hair follicle stimulation — increasing follicle size, prolonging the growth phase, and improving scalp vascularisation. Sharp Labs supplies GHK-Cu as a ready-to-use injectable solution at ≥98% HPLC purity. No reconstitution required. Certificate of Analysis included with every order.
