GHK-Cu Peptide Synthesized and Lyophilized in Canada by Koi Peptides Domestic Synthesis at a Canadian Facility Synthesis of the Gly-His-Lys tripeptide is carried out by solid-phase peptide chemistry at a Canadian production partner, with copper coordination introduced as a separate complexation step against the purified free peptide
A 2021 study published in the International Journal of Cosmetic Science evaluated a formulation containing biopeptides from rice and lupin combined with 10% natural vitamin C
Additionally, the lower concentration of benzyl alcohol found in bacteriostatic water for peptide reconstitution prevents it from affecting the stability or integrity of the peptide being dissolved in it
