What Is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper peptide found in human plasma, saliva, and urine. First identified in the 1970s, it has since become one of the most researched peptides for skin regeneration, wound healing, and anti-aging applications.
Catalyst Peptides supplies GHK-Cu as a 100mg vial with 2mL Bacteriostatic Water — a high-concentration option suited for serious research protocols.
Key Research Areas
Collagen & Skin Remodelling
GHK-Cu has been shown in research to stimulate the production of collagen, elastin, and glycosaminoglycans — the structural proteins responsible for skin firmness, elasticity, and hydration. It also activates the skin's own repair mechanisms, making it a focus of anti-aging and dermatology research.
Wound Healing
One of GHK-Cu's most studied properties is its ability to accelerate wound healing. Research suggests it promotes the proliferation of fibroblasts (the cells that produce collagen), increases blood vessel formation, and reduces inflammation at wound sites.
Anti-Inflammatory Effects
GHK-Cu modulates inflammatory pathways, which may contribute to its skin-calming and tissue-repair properties. This makes it of interest in research involving chronic inflammation and skin conditions.
Hair Follicle Stimulation
Some research indicates GHK-Cu may stimulate hair follicle size and growth, making it a subject of interest in hair loss research alongside its skin applications.
Topical vs Systemic Use in Research
GHK-Cu is unique among peptides in that it is studied both as a topical agent (applied directly to skin) and systemically. Many skincare researchers use it in topical formulations, while others study its systemic effects via reconstitution and injection protocols.
Reconstitution
Your GHK-Cu 100mg vial comes with 2mL Bac Water included. Follow our step-by-step reconstitution guide for full instructions. GHK-Cu dissolves readily and the solution should appear clear to slightly blue-green in colour — this is normal due to the copper complex.
Storage
- Unreconstituted powder: store in a cool, dry place away from light and moisture.
- Reconstituted solution: refrigerate at 2–8°C, use within 28 days.
Why 100mg?
At 100mg, Catalyst Peptides' GHK-Cu vial offers a high-yield option for researchers running extended protocols or topical formulation work, reducing the need for frequent reordering.
