GHK-Cu was first characterized by Dr. Loren Pickart in 1973 while he was studying human blood plasma at the University of Washington. His laboratory work compared biochemical activity between plasma samples from different age cohorts and isolated a small copper-binding peptide that appeared to account for differences observed in the assays.
The peptide was three amino acids long—glycine, histidine, and lysine—bound to a copper ion. Dr. Pickart designated it GHK-Cu. Subsequent observational research reported that plasma GHK concentrations varied across age groups, which prompted further laboratory investigation of the molecule.
Over the following decades, published research on GHK-Cu expanded across fibroblast biology, copper-enzyme biochemistry, and gene-expression profiling, with genomic analyses reporting modulation of several thousand genes in cultured cells. GHK-Cu has appeared in peer-reviewed preclinical publications since the 1970s. This product is intended for research use only.
Collagen Synthesis Research

All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months. Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Reconstitute slowly by adding solvent to the side of the vial and allowing it to dissolve without agitation. Do not shake. Store away from direct light. All products are shipped with dry ice or cold packs to maintain cold-chain integrity.
All GHK-CU batches are independently tested by a third-party laboratory for purity and identity verification via HPLC with UV detection coupled with Mass Spectrometry.
