GHK-Cu 50mg — Copper Tripeptide-1
Loren Pickart was not looking for a peptide when he found GHK-Cu. He was studying age-related differences in liver tissue in 1973 and noticed that a small molecule in human plasma — just three amino acids complexed with a copper ion — could shift old tissue toward a younger functional profile. Five decades and over 150 peer-reviewed studies later, GHK-CU 50mg remains one of the most thoroughly investigated copper-peptide complexes in the research literature.
A molecule that programs genes
The Broad Institute’s Connectivity Map database revealed something striking: GHK-Cu affects the expression of roughly 4,048 human genes, approximately 6% of the genome. The pattern is consistent — upregulation of collagen, growth factors, integrins, elastin, decorin, and glycosaminoglycans, alongside downregulation of inflammatory mediators and excess metalloproteinases (Pickart & Margolina, Int J Mol Sci, 2018; PMC6073405).
Plasma levels tell their own story: roughly 200 ng/mL at age 20, dropping to about 80 ng/mL by age 60. The copper(II) ion is not just structural scaffolding — it is functionally active in roughly 30 copper-dependent enzyme systems.

Research areas
Extracellular matrix remodeling
Pickart’s original work in rat wound models established the foundation — GHK-CU 50mg influences collagen synthesis, decorin production, and glycosaminoglycan expression in fibroblast cultures (Nature, 1980; PubMed 7453802).
MMP regulation
Research has examined GHK-Cu’s effects on MMP-2, MMP-9, and TIMP balance — the metalloproteinase system that governs ECM turnover and remodeling.
Antioxidant interactions
Flow cytometry and ESR spin-trapping studies have characterized interactions with SOD activity, glutathione peroxidase pathways, and hydroxyl/peroxyl radical species.
Anti-inflammatory pathways
Preclinical work in cigarette smoke-induced lung inflammation models documented NF-κB pathway modulation and Nrf2 activation effects on inflammatory mediator expression (Pickart & Margolina, 2018).
GHK-Cu vs BPC-157
Different compounds, different mechanisms. GHK-CU 50mg works through copper-dependent enzymatic pathways and gene expression modulation. BPC-157 works through connective tissue models and nitric oxide signaling. Peptide Bio Sciences LTD carries both individually and together in the Glow 50/10/10 blend (GHK-Cu + BPC-157 + TB-500).
