Ghk-cu Research Peptides

GHK-Cu (Gly-His-Lys-Cu²⁺) is a naturally occurring tripeptide-copper complex first isolated from human plasma in the 1970s. Plasma GHK levels decline progressively with age, prompting research interest in supplementation models for tissue regeneration, fibroblast modulation, antioxidant signalling, and copper-mediated enzyme activation. The molecule's small size and stable copper coordination support investigation across topical, subcutaneous, and in-vitro delivery routes.

Active research areas include skin regeneration models, hair follicle research, collagen turnover, wound-healing protocols, and broader tissue-repair investigation. RetaLABS stocks research-grade GHK-Cu in 50mg vials.
