What your skin made better at twenty.

Your body makes this peptide itself, and it makes less of it with the years. That single observation is what started the research: first around skin and collagen, then around hair.
The same reference, in pen format
The molecule is delivered in a sealed cartridge, inside a refillable anodised aluminium pen. It is not an accessory to add on: it is the other way of ordering the same reference, at its own price.
Does it actually work, or is it one more product?
We promise no result. What we can show is what has been published, at what level of evidence, and what those studies do not say. It is all on this page, limits included.
The body makes it on its own, and makes less of it as the years pass. That single observation is what made it worth studying: first around skin and collagen, where the work is most abundant, then around hair and hair density.
GHK-Cu is a complex between a tripeptide — glycyl-L-histidyl-L-lysine — and a copper ion. The GHK tripeptide occurs naturally in human plasma, where its concentration falls with age.
It is studied because it binds copper with high affinity, and because this complex alters, in cell models, the expression of genes involved in extracellular matrix remodelling.
Proposed mechanism: the complex acts as a copper carrier into cells and modulates the activity of transcription factors. The work describes an influence on collagen synthesis and on matrix metalloproteinases. This mechanism is described in vitro; its reach in humans in vivo is a separate question.
GHK-Cu has long been used in topical cosmetics, a field in which human work exists on skin endpoints. On the hair side, a study published in Annals of Dermatology in 2016 compared, in men with androgenetic alopecia, a complex applied to the scalp against placebo: hair count rose by 71.5 at six months in the most favourable group, against 9.6 on placebo, with no adverse events reported. ONE LIMITATION DECIDES HOW THIS STUDY READS: the product tested combines two substances — 5-aminolevulinic acid and the GHK peptide — so the observed effect cannot be attributed to GHK alone. This work concerns local application; it says nothing about any other route and is not a therapeutic evaluation.
The bulk of the mechanism rests on cell culture and animal models.
The distinction between skin application and other routes is decisive and often erased in commercial presentations. Copper is not innocuous: it is a metal whose accumulation carries its own toxicity. Nothing presented here supports a conclusion of benefit outside the cutaneous setting studied.
For laboratory research purposes only. Not for human consumption or therapeutic use.
This reference holds no marketing authorisation as a medicinal product.
No. This reference is not offered for sale: its commercial framework is not settled. No purchase button is shown until it is.
No. This reference holds no marketing authorisation as a medicinal product and is approved by no authority for human use. A publication or a clinical trial never amounts to approval.
The certificate of analysis is supplied with the batch delivered. No batch number or purity figure is published until the real certificate has been entered: we do not display illustrative values.
The storage requirement is not yet on file: the supplier data sheet has not reached us. We would rather say so than assume.
Compatibility is not confirmed for this reference. Until the manufacturer confirms it, we do not claim it.

Conversion not published
How a graduation on the NORYVA pen maps to a volume depends on its mechanism. Its technical sheet is not on file: no conversion is shown until the manufacturer confirms it. We would rather write that than assume it.
