GHK-Cu Dosage & Reconstitution Guide
Reconstitution math, syringe draw reference, and dosing protocols for injectable GHK-Cu research — everything in one place.
What Is GHK-Cu?
GHK-Cu (Glycyl-Histidyl-Lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It has been investigated extensively in preclinical and cosmetic research for its potential effects on skin remodeling, wound healing, and collagen synthesis. GHK-Cu declines naturally with age, which has driven research interest in its potential restorative applications.
GHK-Cu is available in both topical (cosmetic) formulations and injectable research-grade forms. This guide covers reconstitution and dosing math for the injectable lyophilized form only. Topical GHK-Cu products do not require reconstitution.
GHK-Cu is one of the few peptides with FDA-approved topical cosmetic applications under specific formulations. This guide addresses the separate injectable research-grade product category.
Common Research Doses
| Research application | Dose range | Frequency |
|---|---|---|
| General research | 1–2 mg | Once daily |
| Higher range research | 2–3 mg | Once daily |
GHK-Cu is dosed in milligrams (mg).
