GHK-Cu, also listed as copper tripeptide-1, is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine (GHK). GHK was first isolated from human plasma by Loren Pickart in 1973. It binds copper ions strongly, which is why it is usually supplied as the copper complex, and why GHK-Cu in solution has its typical blue colour.
Our GHK-Cu comes as 100mg in a pre-filled 3 ml pen, about 33mg per ml, at 99% purity. The box contains 1 pre-filled pen and 4 pen needle tips. Most UK shops sell GHK-Cu as 50mg vials of powder; this pen holds twice that amount, already in solution. Store at 2–8°C and refrigerate on arrival.
GHK-Cu is also in our GLOW and KLOW blends, at 50mg each, and AHK-Cu 20mg is its closest relative in the range. Compare the two in GHK-Cu vs AHK-Cu, or read what is GHK-Cu for its structure and history. Free tracked UK delivery and card payment.
Ordering, delivery and payment
How fast is delivery, and what is the cut-off?
Delivery is free, tracked and dispatched within 1 working day. The line under Add to cart shows today's order cut-off and the usual arrival day. See delivery and returns for the detail.
What's in the box?
What is in the pack is printed on the pack itself. Ask us before you order if you need to know more.
Which payment methods, and why might a card be declined (VPN, 3-D Secure)?
You pay by card on a secure payment page. A card is most often declined when a VPN is switched on, when the bank's 3-D Secure screen is closed before it finishes, or when the bank blocks an unfamiliar merchant. Switch the VPN off, keep the 3-D Secure screen open until it completes, and try again. If it still fails, contact us.
What if a parcel is lost or damaged?
Email us quoting your order reference. Your rights under the Consumer Rights Act 2015 always apply to goods that are faulty, damaged or not as described. See delivery and returns.
