Product Description

GHK-Cu (glycyl-L-histidyl-L-lysine:copper(II)) is a naturally occurring tripeptide-copper complex first identified in human plasma by Dr. Loren Pickart in 1973. It is found in plasma, saliva, and urine, with plasma levels declining significantly with age — from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60. GHK-Cu has a high affinity for copper(II) ions and has been the subject of extensive research for its roles in stimulating collagen and glycosaminoglycan synthesis, promoting tissue remodeling, activating wound repair processes, and modulating gene expression related to anti-inflammatory and antioxidant pathways.

Certificate of Analysis

Every batch of GHK-Cu sold by CertPeptides is independently tested by a third-party laboratory. The Certificate of Analysis (COA) confirms identity, purity (≥99% via HPLC), and the absence of heavy metals and microbial contamination.

A COA is included with every order. You may also request a batch-specific COA through our contact page.

Laboratory Product Information

📦 Includes

One (1) vial of GHK-Cu lyophilized powder (50mg per vial), Certificate of Analysis (COA). Reconstitution with acetic acid 0.6% recommended to maintain Cu²⁺ coordination stability.

🔬 Purpose

GHK-Cu is a naturally occurring tripeptide–copper(II) complex found in human plasma and tissues. It is studied in in-vitro models for effects on collagen synthesis in fibroblast cultures, decorin expression, metalloproteinase modulation, and antioxidant gene regulation.

🧬 Ingredients

GHK-Cu (Gly-His-Lys:Cu(II)) tripeptide–copper complex lyophilized powder, ≥99% purity (HPLC verified). No fillers, binders, or excipients.
