What is GHK-Cu?
GHK-Cu (glycyl-L-histidyl-L-lysine:copper(II)) is a tripeptide naturally present in human plasma, saliva, and urine. It was first isolated from human plasma in the 1970s. The peptide has a strong affinity for copper(II) ions, and this copper-bound form is believed to be its most biologically active state. GHK-Cu levels decline significantly with age, which has led to research interest in its potential anti-aging applications.
What It's Used For
Research focuses on skin regeneration and anti-aging studies, wound healing acceleration, hair follicle stimulation, collagen and elastin synthesis, anti-inflammatory effects, and antioxidant activity. GHK-Cu is found in many cosmetic formulations and is also researched in injectable form for systemic effects.
How It Works (Mechanisms Explained)
GHK-Cu appears to work through multiple mechanisms. It stimulates collagen synthesis and the production of decorin and other glycosaminoglycans that support skin structure. It promotes blood vessel growth (angiogenesis) which is crucial for wound healing. The peptide also attracts immune cells to sites of injury, modulates inflammation, and has antioxidant properties. Additionally, GHK-Cu influences gene expression, reportedly resetting genes to a healthier pattern of activity.
Common Research Stacks
In research and cosmetic applications, GHK-Cu is sometimes combined with other regenerative peptides or growth factors. For systemic research, it may be studied alongside other anti-aging interventions. Topical formulations often combine it with other skin-supportive ingredients.
Common Beginner Mistakes
Confusing topical and injectable applications (they serve different purposes), expecting overnight results (tissue regeneration takes time), using products with inadequate GHK-Cu concentration, improper storage of reconstituted injectable forms, and not understanding the role of copper in the peptide's function.
Reconstitution Basics
Injectable GHK-Cu comes as lyophilized powder requiring reconstitution with bacteriostatic water. Use sterile technique, add water slowly along vial wall, swirl gently until fully dissolved (solution should be clear blue due to copper content). Refrigerate after reconstitution and use within 28 days. Both subcutaneous and topical applications are researched.
