Ranked board
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 randomised 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
Ranked by 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. Nothing is pinned, sponsored, or lifted into position.

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.

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
Not one company reviewed here publishes a certificate of analysis a customer can read. Until that changes, nothing on this site can tell you what is in a vial.
Frequently asked questions
Why is GHK-Cu not affected by the compounding restriction?
The FDA PCAC list that has emptied this network's BPC-157, TB-500, CJC-1295, ipamorelin, MOTS-c, KPV, epitalon and semax boards does not include GHK-Cu, and the companies here 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.
