GHK-Cu Reference
Educational, not medical advice reference for GHK-Cu: Skin/Hair, Recovery; regulatory status, evidence posture, source review, and schedule note…
Reference summary
Topical and skin-penetration literature is stronger than injectable human evidence. Published work includes ex vivo human skin permeation studies (Hostynek 2010), animal wound-healing models, and a body of Pickart-led reviews summarizing GHK and GHK-Cu effects on fibroblast activity, dermal matrix remodeling, antioxidant gene expression, and hair-follicle signaling. No adequately powered randomized human trial demonstrates that injectable GHK-Cu reproduces those effects systemically.
Regulatory and posture
- Categories
- Skin/Hair, Recovery
- Aliases
- Copper tripeptide-1, GHK copper, Glycyl-L-histidyl-L-lysine copper(II), Prezatide copper acetate
- Evidence posture
- translational - Topical and ex vivo evidence are stronger than injectable human data.
- Regulatory status
- No FDA-approved injectable GHK-Cu drug label. GHK-Cu is widely sold as a cosmetic ingredient at low concentrations under skincare and haircare claims, where it is regulated as a cosmetic rather than a drug. Most published evidence is topical, transdermal, cosmetic, or animal wound-model research; the injectable preparations sold in research-vial channels are not the same regulatory category as the cosmetic ingredient and carry no FDA quality oversight.
