GHK Basic 200mg (Tripeptide-1) Topical Overview
GHK Basic 200mg (Tripeptide-1) Topical from Peptide Science is the standard topical research formulation of the uncomplexed glycyl-L-histidyl-L-lysine tripeptide, supplied for in-vitro fibroblast and dermal-cell research.
Compound Class and Mechanism
GHK (formally designated Tripeptide-1 in INCI cosmetic nomenclature) is the uncomplexed form of the same tripeptide also sold in this catalogue as the copper-bound GHK-Cu and the palmitoylated Pal-GHK forms. Preclinical research has characterised the free tripeptide for cell-culture effects on collagen synthesis and fibroblast activity, with distinct binding kinetics from the copper-bound form because the copper coordination changes the secondary structure of the peptide.
