GHK-Cu Vial 50mg

GHK-Cu is a naturally occurring copper-binding tripeptide whose levels decline with age. Researchers study it for stimulating collagen and elastin, improving skin firmness and tone, supporting hair follicles, and signaling tissue remodeling and wound repair. Supplied as a compounded, lyophilized vial from a US-licensed pharmacy — reconstitute with bacteriostatic water and store refrigerated at 2–8°C, so you can dial dose and cadence to your protocol. For use under licensed-provider supervision.
