Buy GHK-Cu Copper Peptide — Tissue Repair & Renewal
GHK-Cu (copper-binding tripeptide glycyl-L-histidyl-L-lysine) is a naturally occurring small peptide originally isolated from human plasma by Loren Pickart in 1973. In its copper-bound form it functions as a regenerative and anti-inflammatory signalling molecule, and in the intervening decades it has accumulated a substantial body of published research on skin repair, hair follicle stimulation, and wound healing.Mechanism of actionGHK-Cu modulates several biological pathways relevant to tissue repair: it chelates copper and delivers it to target tissues, upregulates collagen and glycosaminoglycan synthesis in fibroblasts, influences the expression of genes involved in DNA repair and anti-inflammatory signalling, and stimulates hair follicle keratinocyte proliferation. Gene-chip studies summarised in the 2018 review in the International Journal of Molecular Sciences show that GHK-Cu resets thousands of age-related gene expression changes toward a younger profile.Evidence from peer-reviewed researchA 2012 paper in BioMed Research International reviewed the peptide's role in preventing oxidative stress and age-related degeneration. A 2018 review in the International Journal of Molecular Sciences catalogued its regenerative and protective effects supported by gene-expression data. Earlier dermatological research had already shown that copper-binding peptide creams improve the ultrastructure of sun-damaged skin.Typical research protocolsIn topical research use, GHK-Cu is formulated into serums or creams at low micromolar concentrations. In injectable research contexts, it is reconstituted with bacteriostatic water and used in rodent wound-healing and hair-growth models. PEPTEX includes GHK-Cu in its GLOW and KLOW blended products.Quality and purityPEPTEX GHK-Cu is supplied as a pre-chelated copper complex (visible blue colour in solution) to ensure bioactive copper delivery, verified to ≥99% peptide purity by HPLC.Storage and handlingStore lyophilised GHK-Cu at −20 °C, protected from light. After reconstitution with bacteriostatic water, store at 2–8 °C and use within 12 weeks.

Customer Reviews
Наталья К. — ★★★★★
Skin, nails, hair — all improved after three months on ghk-cu. The gene expression modulation affects tissues system-wide. That's the advantage of subcutaneous injection over topical-only application. Peptex quality is consistently excellent.
Lotte_nl — ★★★★
Good product. Expected more dramatic results based on what I read, but the improvements are real, just gradual. Skin does feel firmer, small cuts heal faster. More of a long-term investment than a quick fix.
Filippo — ★★★★★
On my fourth vial. At 1mg/day subQ, a 50mg vial lasts almost two months. That's excellent value. The effects on skin firmness and overall tissue quality are cumulative over cycles. Peptex consistency is why I stick with them.
Bram87 — ★★★★★
Using GHK-Cu both subcutaneously and topically (mixed into my serum). The injectable provides systemic gene expression effects. The topical targets my face specifically. Peptex quality dissolves perfectly for both applications. 50mg vial lasts ages.
Matteo R. — ★★★★★
Combined GHK-Cu with my microneedling sessions. The recovery time was cut in half and the collagen induction results were significantly better according to my esthetician. Peptex quality makes a difference in sensitive applications like this.

Frequently Asked Questions
What is GHK-Cu and why is it called the "youth peptide"?
GHK-Cu (glycyl-L-histidyl-L-lysine with copper ion) is a copper peptide complex involved in tissue regeneration and gene activity regulation. GHK-Cu stimulates the synthesis of collagen, elastin, and glycosaminoglycans, directly affecting skin structure, density, and elasticity. It is called the "youth peptide" because it activates over 4,000 genes associated with tissue repair, and natural GHK-Cu levels decline with age — replenishing it helps slow visible signs of aging.
How does GHK-Cu affect skin and hair?
GHK-Cu has a comprehensive effect on skin: stimulates fibroblasts to produce collagen and elastin, improves microcirculation, accelerates damage healing, reduces wrinkle depth, and increases skin firmness. For hair, GHK-Cu is beneficial because it increases hair follicle size, stimulates hair growth, and extends the anagen (active growth) phase. It is one of the few peptides with proven dual action — on both skin and hair.
How to take GHK-Cu?
GHK-Cu is administered subcutaneously daily at a dosage of 1–3 mg. The course lasts 2–6 months. For visible skin results, at least 2–3 months of use is recommended; for hair — 3–4 months. For storage up to 90 days, reconstitution in bacteriostatic water is recommended.
