GHK-Cu
This product is for laboratory research use only. Not for human or veterinary use. Not a drug, supplement, or medical device.
GHK-Cu is supplied by Bench Grade Peptides as a lyophilized powder in a sealed, lot-numbered vial, for laboratory research use only — not for human or veterinary use.
Its published Certificate of Analysis (lot 00011/0011, analyzed September 3, 2026) is from AV Analytics, a third-party laboratory, and reports 99.79% purity by HPLC; every published lot is listed on the product's COA page. Vials ship at ambient temperature in protective packaging from Florida (Bench Grade Peptides LLC is registered in Dover, Delaware), with storage notes on the lot's certificate.
Under the Bench Grade Guarantee, if an ISO 17025-accredited US laboratory of the buyer's choosing reports a result that disagrees with the published Certificate of Analysis, Bench Grade refunds the order and shipping to the original payment method and pays the lab fee plus $100 separately, by a payment method arranged with the buyer.

Storage & handling
Lyophilized GHK-Cu is shipped at ambient temperature in protective packaging. For long-term laboratory storage, keep vials sealed at –20°C, and where your lot's Certificate of Analysis is published, follow its storage notes.
Handling & reference
- GHK-Cu — handling a copper complex, not a plain peptideGHK-Cu is a tripeptide bound to a copper(II) ion. The metal changes the mass, the colour, the light sensitivity and what a purity figure even means.
- GHK-Cu vs KPV: metal complex or plain peptideTwo small tissue-research peptides with a fundamental difference: one carries a copper ion as part of the compound, the other does not. That changes storage, colour and COA reading.
