GHK-Cu

GHK-Cu — The Beauty Peptide

• Boosts collagen
• Tightens skin
• Improves hair health

Overview

This product is supplied as a kit, not as a pre-filled cartridge. Everything needed to prepare a pen cartridge is included — the powder is shipped sealed and lyophilised, and is reconstituted by you at the point of use rather than by us before dispatch.

A reconstituted cartridge is a liquid preparation with a limited stable life, and transit conditions cannot be controlled. Supplying the compound dry removes that variable entirely: the material arrives in the state it was tested in, and the clock only starts when you mix it. Available in 50mg and 100mg.

What’s in the kit

• 1 × GHK-Cu vial — lyophilised powder, 50mg or 100mg as selected
• 1 × bacteriostatic water, 3ml — for reconstitution
• 1 × pen cartridge — empty, ready to fill
• 1 × insulin needle

The cartridge fits our peptide pens. Our reconstitution calculator will work out the concentration and draw volume for the water volume you use.

Research Focus

GHK-Cu is a copper tripeptide — glycyl-L-histidyl-L-lysine complexed with copper(II) — found naturally in human plasma, where its concentration declines with age. Published work has examined collagen and elastin synthesis, skin remodelling and wound repair, stimulation of hair follicles, antioxidant activity, and broad modulation of gene expression.

Research on GHK-Cu includes human topical studies as well as animal and in-vitro work. Our summary of the published literature is here: GHK-Cu Dosage: What Studies Have Actually Investigated.

Testing & Certificates of Analysis

Kits contain the same independently tested powder as our standalone vials — HPLC purity and mass-spectrometry identity, certified per batch and published on our lab results page.

Returns

Kits are assembled to order. An unopened kit with all seals intact can be returned within 14 days — but once the vial, water or needle seal has been broken it cannot be accepted back on hygiene grounds, and anything already reconstituted cannot be returned. Faulty, damaged or incorrect items are always put right. See our refund policy.
