Common questions

GHK-Cu FAQ

Is GHK-Cu the same as copper peptide?

GHK-Cu is the copper-bound form of the GHK tripeptide, commonly referred to as a 'copper peptide' in research contexts.

Why does GHK-Cu appear in two categories?

It is studied in both tissue-repair (Recovery) and aging (Longevity) research models, so it is listed under both.

How do I know a vendor is legitimate?

Look for batch-specific, third-party Certificates of Analysis (COAs), transparent purity testing, U.S. sourcing, and a real reputation across independent review platforms. Our vendor reviews check all of these.

Does Peptides Uncaged sell GHK-Cu?

No. We're an independent research and comparison resource. We link to vetted third-party vendors and disclose every affiliate relationship.

What it costs today

Vendor pricing moves constantly, and the sticker price on a vial is not the number that matters — cost per milligram is. Our sister index reads all four vendor storefronts directly and normalises every listing, so you can see who is actually cheapest right now.
