GHK-CU 50 MG

GHK-Cu is a naturally occurring copper-peptide research compound studied in laboratory settings for its role in collagen synthesis, tissue remodeling, and gene-expression research. Chemically, GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). Each vial from Central Peptides contains 50 mg of high-purity GHK-Cu, third-party verified and supplied with a batch-specific Certificate of Analysis (COA) for research use only. As one of the most extensively studied bioactive copper complexes, GHK-Cu remains a frequently requested compound among Canadian laboratories.

GHK-Cu Research Applications

GHK-Cu is built on the tripeptide GHK — a three-amino-acid chain of glycine, histidine, and lysine — which has a strong natural affinity for copper(II) ions. It was first isolated from human plasma by Loren Pickart in 1973, and is also found in saliva and urine. A notable characteristic studied in research is that GHK-Cu levels in human plasma decline with age, from approximately 200 ng/mL at age 20 to around 80 ng/mL by age 60, which is one reason it is examined in cellular aging research models.

In controlled laboratory environments, researchers study GHK-Cu for its reported role in stimulating collagen and glycosaminoglycan synthesis in skin fibroblasts, modulating the expression of a large number of human genes, and supporting tissue-remodeling and antioxidant research models. Its copper-binding behavior is central to many of these investigations.

Common research areas where GHK-Cu is examined include:

• Collagen and glycosaminoglycan synthesis research models
• Skin fibroblast and tissue-remodeling research
• Copper coordination chemistry and metal-peptide studies
• Gene expression modulation and cellular aging research

Purity and Quality Verification

Every batch of GHK-Cu sold by Central Peptides is manufactured under controlled synthesis and purification processes to ensure stability, consistency, and structural integrity for scientific research applications. Our compounds are independently tested and verified at 99% purity through High-Performance Liquid Chromatography (HPLC) and mass spectrometry.

Each order includes access to a batch-specific Certificate of Analysis, allowing researchers to verify identity, purity percentage, and testing details before use. This batch-level traceability is part of our commitment to transparency and quality control across our full research catalog. Researchers who require documented purity standards for their work can review the COA before and after purchase, ensuring every vial meets the same verified specification.

Storage and Handling

GHK-Cu is supplied as a lyophilized (freeze-dried) powder for maximum stability during shipping and storage. The powder typically appears blue to violet, a color that comes naturally from the copper coordination and is normal. Store the lyophilized compound sealed in a cool, dry environment away from heat, light, and moisture.

Once reconstituted for research, GHK-Cu is soluble in water and should be kept refrigerated at 2-8°C. To preserve compound integrity, aliquot the reconstituted material to avoid repeated freeze-thaw cycles, and use within an appropriate window to maintain consistency in research results.

Shipping Across Canada

Central Peptides ships GHK-Cu and all research compounds across Canada in discreet, temperature-conscious packaging. Orders are typically processed within 24 hours and delivered within 3 to 5 business days. Free delivery is available on qualifying orders over the threshold listed at checkout.

As a Canadian-based supplier, we offer domestic fulfillment, which means faster delivery times and fewer customs complications compared to ordering from international sources. Every shipment is packaged to protect the compound during transit and to maintain privacy.
