GHK-Cu sellers, and how far the copper peptide evidence goes

GHK-Cu is the rare case on this site where the evidence is genuinely encouraging: small randomized dermatology trials, in humans, measuring the thing the product is sold for. That makes it the clearest test of a seller's discipline, because there is a supportable claim available and most of these companies still make a bigger one.

What gets on this board

Every published review whose dispensed list includes a product we have graded as GHK-Cu, topical or otherwise. Copper-containing cosmetics that do not name GHK-Cu are not on this board.

What decides the order

Companies we have a paid relationship with are listed first, and we say so here rather than marking individual rows. Within that group and within the rest, the order is the same measured one: how much of what each company sells is described accurately — the share of the products this board counts whose marketing claim matches the trials behind it. Ties go to the company with more matching claims, then to the one that names its pharmacy, then to the one that publishes a testing regime, and last of all to alphabetical order. Being a partner changes where a company sits, never what its numbers say.

What the grading found

Claims that match the trials

Across every one of these companies' GHK-Cu products that we have graded.

Name their pharmacy

A telehealth brand is almost never the pharmacy that fills the order.

The ranking

Every product counted here was graded against the published trials for that molecule, using the company's own words about it. The three counts below are that grading, and they are the ranking — there is no score, no weighting and no adjustment behind them.

Only GHK-Cu products are counted here. A company's GLP-1 or NAD+ claims have no effect on where it lands on this board.

How a claim is graded, and what moves a compound between evidence tiers, is on our methodology page.

What this board does not measure

Whether it works

A company can describe a weakly-evidenced product accurately and rank well here. What the evidence says about each molecule is on its own graded compound page, and the two questions are deliberately kept apart.

Clinical care

We read public pages. We have not been a patient of any of these companies, have not assessed a consultation, and publish no quality score of any kind.

Price

Prices appear on a review as a note where a company publishes one, and they are not part of this ranking. A cheaper company is not lower here and a dearer one is not higher.

Product quality

Only 1 of the companies reviewed here publish a certificate of analysis a customer can read, and a certificate is not on this board's ranking axis. Nothing here tells you what is in a vial.

Frequently asked questions

Why is GHK-Cu not affected by the compounding restriction?

The FDA PCAC restriction list covers BPC-157, TB-500, CJC-1295, ipamorelin, MOTS-c, KPV, epitalon and semax — which is why no boards for those compounds are published here — and it does not include GHK-Cu. The companies on this board continue to dispense it as a prescription topical. If that changes, this board comes down rather than being quietly repopulated.

What does the strongest GHK-Cu claim look like?

A topical, cosmetic, appearance-of-skin claim, phrased at the size the dermatology trials actually reported. Where a row here is graded as reaching past the trials, it is almost always because a systemic or regenerative claim has been attached to a topical product — hair growth, wound healing, tissue repair — none of which those trials tested.

Nothing pinned

Companies we have a paid relationship with are listed first, and we say so here rather than marking individual rows. Within that group and within the rest, the order is the same measured one: how much of what each company sells is described accurately — the share of the products this board counts whose marketing claim matches the trials behind it. Ties go to the company with more matching claims, then to the one that names its pharmacy, then to the one that publishes a testing regime, and last of all to alphabetical order.
