Overview
Copper Peptide GHK-Cu, commonly known as Blue Copper Peptide, is a naturally occurring peptide complexed with copper. It was first discovered in human plasma and has since been synthesized for various applications. The peptide is renowned for its regenerative properties, making it a popular ingredient in anti-aging skincare and medical treatments. GHK-Cu is a tripeptide (Glycyl-Histidyl-Lysine) bound to a copper ion. This unique structure allows it to interact with cellular processes, promoting tissue repair and reducing inflammation. Its blue color is due to the copper ion, which also enhances its stability and bioavailability.
Physical and Chemical Properties
GHK-Cu is a blue-colored compound, either in powder or solution form. It is highly soluble in water, which makes it easy to incorporate into aqueous formulations. The copper ion in the peptide provides stability and enhances its biological activity. The molecular weight of GHK-Cu is 403.92 g/mol, and its CAS number is 89030-95-5. The peptide is stable under normal storage conditions but should be protected from light and excessive heat to prevent degradation. Its antioxidant properties are attributed to the copper ion, which scavenges free radicals and reduces oxidative stress.
Main Applications
GHK-Cu is primarily used in skincare products, particularly anti-aging creams and serums. It stimulates collagen and elastin production, reducing wrinkles and improving skin elasticity. The peptide also has wound-healing properties, making it useful in medical applications for burns and surgical recovery. In addition to skincare, GHK-Cu is used in hair growth treatments. It promotes hair follicle health and can reduce hair loss. The peptide's anti-inflammatory effects also make it suitable for treating conditions like acne and rosacea. Its versatility and safety profile have led to widespread adoption in cosmetic and pharmaceutical industries.
Safety and Storage
GHK-Cu is generally considered safe for topical use, with minimal side effects reported. However, it should not be ingested or applied near the eyes. Patch testing is recommended for individuals with sensitive skin. Storage conditions are critical to maintaining the peptide's stability. It should be kept in a cool, dry place, away from direct sunlight. Solutions should be stored in airtight containers to prevent contamination. Proper handling and storage ensure the peptide retains its efficacy over time.
B2B Procurement Guide
When procuring GHK-Cu, B2B buyers should prioritize purity and supplier reliability. Look for suppliers who provide certificates of analysis (CoA) confirming purity levels of ≥98%. GMP and ISO certifications are indicators of a reputable supplier. Price varies based on purity and quantity, with bulk purchases often offering cost savings. Buyers should also consider the form (powder or solution) that best suits their manufacturing processes. Establishing long-term relationships with trusted suppliers can ensure consistent quality and timely delivery.
