Research Focus

GHK-Cu is a copper tripeptide — glycyl-L-histidyl-L-lysine complexed with copper(II) — found naturally in human plasma, where its concentration declines with age. Published work has examined collagen and elastin synthesis, skin remodelling and wound repair, stimulation of hair follicles, antioxidant activity, and broad modulation of gene expression.

Research on GHK-Cu includes human topical studies as well as animal and in-vitro work. Our summary of the published literature is here: GHK-Cu Dosage: What Studies Have Actually Investigated.

Testing & Certificates of Analysis

Cartridges are filled from the same independently tested material as our powder vials — HPLC purity and mass-spectrometry identity, certified per batch and published on our lab results page.
