Buy GHK-Cu Online

Peptara Labs sells GHK-Cu online as a 100mg research-grade vial of lyophilized copper peptide, ordered from this page. GHK-Cu is sold in two forms that are not interchangeable, a low-concentration ingredient in topical skincare and research-grade powder in a vial, and the vial is what Peptara Labs sells.

One 100mg vial is $200 USD, which is $2.00 per mg. Signing up by email takes 15 percent off a first order, which brings a vial to $170. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $120 each.

A copper peptide serum is a topical skincare product that carries GHK-Cu, the same copper tripeptide, at low concentration in a leave-on cosmetic base. The peptide is identical; the difference is the form, so a price comparison between a serum and a vial is not like for like. The strongest human skin evidence for GHK-Cu comes from this cosmetic format: topical trials that measured denser, firmer skin and reduced line depth over about 12 weeks (Pickart and Margolina, Int J Mol Sci 2018, PMID 29986520). What Peptara Labs ships is a research-grade 100mg vial of lyophilized powder for laboratory study, not a cosmetic serum, and it is sold for research use rather than personal application.

Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250. US orders ship free in 2 to 3 days when every item ships from the US warehouse.

Read certificate COA-2026-4173 for the released batch, lot GHKCU-260417-A: 99.62 percent purity by HPLC, identity by LC-MS and 106.09 mg of net peptide in a 100mg vial, tested by Titreon Analytical, with an independent Janoshik endotoxin report on the same batch. Vials ship unlabeled, so after delivery your order number on WhatsApp is what ties your vial to its batch certificate.

One sealed 100mg vial of lyophilized GHK-Cu and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.

GHK-Cu ships as a lyophilized, freeze-dried powder, which is stable at room temperature for weeks, so it travels without refrigeration. After reconstitution with bacteriostatic water the vial belongs in a refrigerator, and storage instructions are included with every order.

Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.

We're a team of expats and locals. We started Peptara Labs because sourcing quality research peptides was a mess: $500+ vials abroad, anonymous Telegram sellers, or overseas shipments that might not survive customs. So we built what we wished existed. Third-party tested material with a published certificate of analysis, fast delivery, and a team that answers every WhatsApp message about certificates, storage, shipping and orders. This isn't a faceless storefront.

Every GHK-Cu vial comes with a third-party Certificate of Analysis (COA) confirming 98%+ purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.

GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine bound to a copper ion. GHK is found naturally in human plasma, at a concentration that falls by roughly 60 percent between age 20 and 60. Bound to copper, it acts as a signaling molecule: in cell studies it stimulated fibroblast collagen production at very low concentrations (Maquart et al., FEBS Lett 1988, PMID 3169264), and reviews describe it modulating a broad set of genes involved in skin repair (Pickart and Margolina, 2018; Dou et al., 2020).

The human skin studies tested topical GHK-Cu formulations and measured skin over about 12 weeks, reporting denser, firmer skin with reduced line depth (Leyden et al. and Abdulghani et al., summarized in Pickart and Margolina, Int J Mol Sci 2018, PMID 29986520). In one 12-week comparison, collagen production improved in more treated women on GHK-Cu (70 percent) than on retinoic acid (40 percent) or vitamin C (50 percent): one study, one metric, not a general ranking (Abdulghani et al., in Pickart and Margolina, 2018).

GHK-Cu is sold as a single 100mg vial, and it is also one of the four peptides in the KLOW blend, alongside BPC-157, TB-500 and KPV. Each of those is studied separately for tissue-repair or skin endpoints; the combination itself has no published trial. GHK-Cu also appears in the research stacks listed on this page, which group catalog compounds from one research area and have not been tested as a combination.

GHK-Cu has been studied for effects on hair follicles and appears in several hair-focused peptide formulations. The published record here is thinner than the skin record. One in vitro study examined the tripeptide-copper complex and human hair growth in cultured cells (Pyo et al., 2007), the kind of early, non-clinical evidence the hair record largely rests on.

We offer a 60-day money back guarantee: verified purity, a certificate of analysis, and correct fulfillment, or your money back. It is a guarantee on the material and on how the order is handled, and on nothing else. Our team stays reachable on WhatsApp for questions about certificates, storage, shipping and orders.

Neither. The 100mg vial is sold for research use only, for laboratory research, not as a cosmetic and not as an approved medicine.

The lyophilized powder is reconstituted with bacteriostatic water, which ships in the order. The Peptara Labs standard is 2 mL of bacteriostatic water for every vial, which puts the 100mg GHK-Cu vial at 50 mg per mL: the milligrams in the vial divided by the millilitres of water added. Once reconstituted, the vial belongs in a refrigerator, and storage instructions are included with every order.

You can. But you don't know what's in them, who made them, or how they were stored. Telegram sellers operate anonymously with no accountability. No COA. No real company behind them. No support if something goes wrong. Our price includes third-party testing, fast delivery, bacteriostatic water, COA access, and educational support. We don't just sell peptides. We stand behind the quality of what you're paying for.
