GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) complex that plays crucial roles in tissue repair and regeneration. As a key regulator of copper homeostasis and signaling, this small but potent peptide-copper complex demonstrates remarkable wound healing, anti-inflammatory, and anti-aging properties in research models. Our research-grade GHK-Cu is synthesized with precise 1:1 copper-peptide stoichiometry for consistent biological activity in dermatological and regenerative studies.
