— About this compound
GHK is a naturally occurring tripeptide with the amino-acid sequence glycyl-L-histidyl-L-lysine. When complexed with copper(II), the resulting GHK-Cu chelate forms a planar coordination structure that is the bioactive form referenced in most of the published research literature.
GHK-Cu is one of the most extensively studied copper-binding peptides in cell-biology research. Pickart and colleagues have demonstrated effects on a wide range of gene-expression endpoints in cultured cells, with particular focus on dermal fibroblast and hair follicle research models.
— Mechanism
Modulates gene expression in cultured fibroblasts (downregulation of TGF-β and upregulation of decorin reported in dermal research models). Facilitates copper transport across cell membranes. Has been associated with anti-inflammatory cytokine profiles and fibroblast activation in preclinical work.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
