GHK-Cu 30 mg peptide pen
The copper tripeptide at thirty milligrams, the entry-sized unit of the best-documented dermal compound in the catalogue, in its characteristic blue.
- ISO-certified laboratory
- COA per batch, ≥99% HPLC
- Discreet dispatch within 24 h
- Research use only
The blue tripeptide, at working size
Gly-His-Lys complexed with copper, pre-filled at 30 mg: the smaller of our two GHK-Cu units, sized for protocols that consume modest total quantities. The colour is functional, the copper complex is blue, and fading is a handling signal, not a cosmetic quirk.
Among skin-research compounds GHK-Cu carries the most substantial literature, collagen synthesis markers, wound-model work, and the shortest inferential distance to established cosmetic science, which the compound page sets out without overreaching.

The best-read dermal file, and its honest edges
Best-documented in this catalogue is a real claim, and a modest one worth stating precisely.
Among the compounds on this site GHK-Cu carries the fullest research file, and it is worth being exact about what that file contains. The literature runs to collagen-synthesis markers in cell culture and healing endpoints in animal wound models, with a comparatively short conceptual jump to the cosmetic-ingredient science that has studied the tripeptide for years. Most of that cell and wound-model work is retrievable through GHK-Cu on PubMed. Researchers who buy ghk-cu 30 mg as an entry unit are working with the dermal compound whose claims rest on the most actual data here.
The honest edge is that best-documented on this shelf is a relative standing, not a clinical endorsement. Most of the strongest work is preclinical, cell and animal models, and much of the human-facing evidence concerns topical cosmetic formulations rather than the material in a pen. Those are related questions, not the same one, and the inferential gap between a culture dish and an injected research protocol is real. The compound reads well because that gap is stated, not papered over.
Your batch on paper, line by line
A certificate is only useful if you can read it, so here is what each line of this batch’s COA is telling you.
Start at the top of the certificate with the lot number, because everything below it is only meaningful for that specific batch; a COA from an older lot describes material you are not receiving. The purity figure, taken by HPLC, tells you how much of the sample is the intended tripeptide rather than unrelated peptide; the general anatomy of such a document is on the COA page. Read it as a percentage of the content, and treat anything vague about the method as a certificate doing less than its job.
The identity line is the one that says what the material actually is. For this compound it should confirm the Gly-His-Lys tripeptide and its complexation with copper, the two together are what make the material GHK-Cu rather than the bare peptide. The blue in the cartridge is a second, informal identity cue: the copper complex is coloured, so its presence and its fading are both visible without instruments. On arrival, check that the lot printed on the pen matches the one named on your certificate.
