Status as of September 30, 2026.
How do approval and compounding affect injections?
No GHK-Cu medicine had FDA approval at that check, in any form or for any use.
FDA is short for the US Food and Drug Administration. [a]
What request was taken back?
The FDA lists injectable GHK-Cu among ingredients whose requests were taken back; the page’s “current as of” date is April 22, 2026.
Groups had asked the FDA to allow pharmacies to use it as an ingredient in made-to-order injections, then withdrew those requests.
That did not grant approval or clear pharmacies to make an injectable medicine from it. [b]
What is compounding?
Compounding means making medicine for an order instead of using a drug maker’s ready-made product.
A prescription orders medicine and comes from a doctor or other health professional with a licence to prescribe.
Under the rules checked September 26, 2026, a regular compounding pharmacy also has to check whether its starting ingredient is allowed.
- If the official US drug standards book covers the ingredient, it must meet that quality standard and the book’s compounding rules.
- Without such a standard, the ingredient has to be included in a medicine with FDA approval.
- When neither condition is met, the ingredient must be on the FDA’s list of extra ingredients allowed for these pharmacies.
The ingredient also needs a valid report confirming what it contains and a maker registered with the FDA.
At the September 26, 2026 check, injectable GHK-Cu was not on that extra-ingredient list.
The sources checked did not establish that injectable GHK-Cu met either of the other ingredient tests.
Ask the person prescribing it: “What rule covers this pharmacy’s preparation of the exact shot being offered, and can you show me the source?” [c]
Why do some pages mention a different FDA category?
At the September 30, 2026 check, non-injected GHK-Cu was in category 1 under the FDA policy for regular compounding pharmacies.
This is a group of ingredients still being reviewed.
The FDA says it normally will not enforce the ingredient-list rule against a pharmacy that meets the policy’s conditions.
That says when the FDA plans to step in; it does not grant legal permission or drug approval.
That entry excludes injections. [d]
Does a government drug code settle approval?
No—a drug code or a listing in the FDA directory does not establish product approval. [e]
Can I follow the explanation?
Keep the actual source beside the answer, so it can be checked again.
