A trial count is not a verdict

These numbers describe how much has been formally studied in humans, not whether something works or is safe for you. A compound can be tested for one condition and sold for another — which is usually the story. This page is automated aggregation from public registries; no physician has reviewed it.

Common questions about GHK-Cu

How many human trials does GHK-Cu have?

3. That is the number of registered interventional human studies we can find, each listed on this page with a link to its original record.

Is GHK-Cu FDA approved?

No. GHK-Cu is not approved by the FDA for any indication. Compounded or "research use only" preparations are not FDA-approved and receive no premarket review for safety, effectiveness, or manufacturing quality.

What is GHK-Cu actually being tested for?

Registered studies cover: ghk and ghk-cu blood levels, acute standardized cutaneous wounds (punch-biopsy wounds), cutis laxa facialis. Compare that to what it is marketed for — the two lists are often different, which is the whole point of this page.

Where does this data come from?

ClinicalTrials.gov, the US public registry of clinical studies. We count interventional human studies only — observational studies are not evidence of effect. Every trial on this page links to its original record so you can check us rather than trust us.
