Overview
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a sequence naturally present in human plasma. First isolated in 1973, it has accumulated five decades of research on extracellular-matrix remodeling, making it a foundational compound in dermal and cosmetic science.
Published studies have investigated GHK-Cu in the context of collagen and glycosaminoglycan synthesis, matrix metalloproteinase regulation, and gene-expression modulation in fibroblast cultures. These are preclinical and in-vitro observations that do not establish clinical efficacy. It is also one of the most common actives studied in cosmetic formulation R&D.
BioTech Pharma supplies GHK-Cu as a distinctive blue-violet lyophilized powder — the color of the copper-peptide complex itself — for laboratory research use only. Lot-specific analytical documentation may be available and should be confirmed for the applicable material. Availability and commercial terms, including bulk quantities, are confirmed per enquiry.
Research Applications
- Collagen and elastin synthesis studies
- Extracellular-matrix remodeling research
- Fibroblast gene-expression modulation
- Cosmetic and topical formulation R&D

Analytical Data
Lot-specific documentation may be available for the applicable material and must be confirmed per enquiry. Where available, it may include:
- HPLC purity result
- LC-MS identity confirmation
- Appearance
- Net content
Request the records you need with your quote and we will confirm availability for your batch.
Procurement Details
Availability, lead time, salt / content basis, and cold-chain requirements depend on the specific lot and quantity, so we confirm them per enquiry rather than publishing fixed figures. Request confirmation for your requirements with your quote and our team will respond with details for the applicable batch.
Storage & Handling
Lyophilized: store at −20 °C, protected from light and moisture. Reconstituted: keep at 2–8 °C and determine working-solution stability empirically per lot, as reconstituted stability varies with diluent, concentration, and handling.
