GHK-Cu (Copper Peptide) is a naturally occurring peptide made from three amino acids — glycine, histidine, and lysine — bound to a copper ion. It is widely known for its potential role in skin rejuvenation, collagen production, tissue repair, wound healing, and hair growth support. Natural levels of GHK-Cu decline with age, which has led to growing interest in its use for anti-aging and regenerative wellness. Potential benefits associated with GHK-Cu include: Increased collagen and elastin production Improved skin firmness and elasticity Reduction in fine lines and wrinkles Support for wound healing and tissue repair Hair growth and scalp health support Anti-inflammatory and antioxidant effects Enhanced skin texture and overall appearance Support for healthy aging and recovery processes GHK-Cu is commonly found in: Topical serums and skincare products Hair and scalp treatments Research peptide formulations Possible side effects may include: Skin irritation or redness Temporary sensitivity at application sites Mild itching or burning sensations Potential reactions related to copper sensitivity in some individuals While GHK-Cu has been studied extensively for skin health and regenerative applications, many uses remain investigational, and injectable forms are not FDA-approved. Most commercially available products are sold as cosmetic or research compounds. Vial arrives in crystal form, for research purposes only.
