GHK-Cu Copper Peptide

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper Complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It is unique because it is one of the few peptides that naturally incorporates a metal ion (copper). Research focuses on its role in wound healing, collagen synthesis, and antioxidant defense mechanisms.

Store GHK-Cu at 4°C (refrigerator temperature), protected from light. Unlike most peptides in our catalog, GHK-Cu does not require -20°C storage. The copper complex is inherently more stable at refrigerator temperatures. Avoid exposure to strong acids or bases which can disrupt the copper coordination.

GHK-Cu maintains ≥95% stability for 18+ months when stored at 4°C protected from light. The copper complex provides additional stability compared to uncoordinated peptides.

Every batch is independently tested by accredited third-party laboratories with full Certificates of Analysis (COA) available on request. We guarantee ≥98% purity across our catalog, use pharmaceutical-grade lyophilization, and ship with cold-chain packaging to preserve compound integrity. Our research-grade peptides are manufactured under strict GMP-compliant conditions, ensuring consistency and reliability that many competitors cannot match.

Yes. We can provide HPLC, mass spectrometry, endotoxin testing, and amino acid analysis reports for any product. If you need a specific assay or custom testing protocol for your research, contact us at [email protected] and we will coordinate with our laboratory partners to accommodate your requirements.

Absolutely. We offer tiered pricing for research institutions, universities, and laboratories ordering in volume. Discounts typically start at 10+ units and scale with quantity. Contact us at [email protected] with your institutional details and estimated quantities for a custom quote. We also support purchase orders (PO) for qualifying institutions.

All orders ship free with same-day processing (orders placed by 12 PM PST). Packages are sent via USPS Priority or UPS Ground with temperature-controlled packaging. Lyophilized peptides are shipped with cold packs to maintain stability. Domestic orders typically arrive within 2–3 business days. Tracking information is provided via email as soon as your order ships.

Due to the nature of research chemicals, we cannot accept returns on opened products. However, if your order arrives damaged, contaminated, or does not meet the stated purity specifications, we will replace it or issue a full refund. Please contact support within 48 hours of delivery with photos of any issues.
