skin
Been using it a couple months. skin on my hands and forearms looks better, less crepey. cheap enough that its not a big deal either way.

Works but the copper smell takes getting used to. fine once you know. cheaper than the serums I was buying.

Bought for hair and skin. hair is too early to tell but skin is definately smoother. will keep going.

Research overview
Kits Peptides is a Canadian research peptide supplier based in Kitsilano, Vancouver, BC. We supply GHK-Cu, a copper-binding tripeptide, for laboratory research use only, with supplier certificates of analysis published.
Glycyl-L-histidyl-L-lysine complexed with copper(II), a tripeptide found in human plasma and widely examined in cell-signalling and skin-science literature. Supplied as a research-grade reference standard, laboratory research use only.
Provided strictly as a laboratory reagent. Not for human or veterinary use.
Information provided for research reference only. No claims are made regarding safety or efficacy for any use in humans or animals.
What GHK-Cu is
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine. The peptide itself is three residues, Gly-His-Lys, and the histidine imidazole together with the terminal amine and the peptide backbone give it a high affinity for copper, which is why it is handled as a defined copper complex rather than as a plain peptide. It is also catalogued as copper tripeptide-1.
The molecular data table above records CAS 89030-95-5, the formula C14H24N6O4Cu and a molar mass of 401.94 g/mol. GHK occurs naturally in human plasma, and the literature commonly notes that measured plasma concentrations decline with age, which is part of why the molecule attracted research interest.
What the research literature covers
GHK-Cu appears in cell-signalling and copper-biochemistry literature, where it is studied both as a copper-delivery molecule and as a signalling peptide in its own right.
Published studies have reported changes in collagen and extracellular-matrix gene expression in fibroblast cultures, effects in dermal injury models in animals, and broad shifts in gene-expression profiling experiments on cultured cells. Its copper-binding constant and redox behaviour are characterised in the analytical literature.
The findings above come from animal, cell and in-vitro models rather than from controlled trials in people, and GHK-Cu is not an approved medicine in Canada. What we supply is a laboratory reagent, not for human or veterinary use.
Kits Peptides supplies GHK-Cu as a laboratory reagent. Describing this literature is not an offer of it for any purpose studied in that literature, and nothing on this page is guidance for use in humans or animals.
What is in the vial
GHK-Cu is supplied as a lyophilized (freeze-dried) powder in a sealed glass vial. The label carries the compound name, the nominal mass in milligrams, our batch code and the research-use statement. The powder is characteristically blue from the coordinated copper, which is expected and not a sign of contamination.
Vials ship unopened. Store as the label directs on arrival; the storage guide in the research library covers the general handling of lyophilized peptides. Bacteriostatic water is sold separately as a supply item and is not included unless your order lists it.
Sizes
GHK-Cu is stocked in the sizes listed above, including a multi-vial kit at the largest size. Larger nominal masses are priced lower per milligram and quantity discounts apply automatically on top of that.
How this lot is documented
Each order records the batch that filled it, and the batch code is printed on the vial label. Where a third-party certificate of analysis exists for the production lot of GHK-Cu we received, it is linked in the certificate section above and on the lab results page.
Read those certificates for what they are: they were issued by the laboratory named on them to our supplier for that production lot, and our batch code is the internal receipt reference we assign, so it does not appear on the PDF. We do not currently commission testing in our own name, and product titles make no purity claim for lots without a certificate. The lab standards page explains the full position.
Shipping from Vancouver
Every order is packed in Kitsilano, Vancouver and ships domestically. Nothing crosses a border, so there is no international transit and no customs hold.
Metro Vancouver addresses can choose same-day courier delivery, priced by distance from our dispatch point; the cutoff for same-day is shown at checkout once you enter a postal code. Everywhere else in Canada ships tracked Canada Post, with the tracking number on your confirmation page and on the order tracking page. Free shipping applies above the threshold shown on the shipping page.
How to order
Choose a size, add it to the cart and check out. Checkout records a short attestation that you are 19 or older and purchasing for laboratory research. Payment is by Interac e-Transfer, card, or cryptocurrency; the confirmation page shows the exact steps for the method you picked, and the same steps are emailed to you.
If a size shows as sold out, the waitlist button on that size emails you when it is back. Quantity discounts apply automatically above the subtotals listed on the shop page and do not stack with promo codes.
Common questions
- What is GHK-Cu?
- The copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, also catalogued as copper tripeptide-1. CAS 89030-95-5, formula C14H24N6O4Cu, molar mass 401.94 g/mol.
- Why is the powder blue?
- The coordinated copper(II). A blue or blue-violet lyophilate is the expected appearance for the copper complex.
- Is GHK-Cu the same as GHK?
- No. GHK is the bare tripeptide; GHK-Cu is that tripeptide complexed with copper(II), which is a different molecular entity with its own CAS number and molar mass.
- Is GHK-Cu approved in Canada?
- Not for any use represented here. It is supplied as a laboratory reagent for research use only, not for human or veterinary use.
- Is there a certificate of analysis for GHK-Cu?
- Where a third-party certificate exists for the production lot we received, it is linked on this page and on the lab results page. Those certificates were issued to our supplier by the laboratory named on them.
- Is GHK-Cu in stock?
- Stock is shown per size above. A sold-out size has a waitlist button that emails you when it returns.
- How is GHK-Cu shipped?
- Same-day courier across Metro Vancouver and tracked Canada Post everywhere else in Canada. Domestic only.
- How do I pay?
- Interac e-Transfer, card, or cryptocurrency.
