What the labels mean

Each peptide page shows one of these labels, with the date it was current as of. A label describes how FDA regulates something. It is one fact about a peptide, not the whole story. An advisory vote is a committee vote on pharmacy compounding. It is not a review for approval.

Key point

An advisory vote is a committee vote on pharmacy compounding. It is not a review for approval.

FDA-approved (Rx) 70
FDA approved a drug with it for the uses on its label. That drug needs a prescription.
Not FDA-approved for this use 3
FDA approved a drug with the same ingredient, but for a different use, dose or form.
Not FDA-approved · advisory vote, no FDA decision 7
An FDA advisory committee has voted on whether pharmacies may compound it. FDA has made no decision. It is not a review for approval.
Investigational 6
Being tested in clinical trials. Not FDA-approved.
Not FDA-approved 89
There is no FDA-approved product. This is the most common status in the Index.
FDA-approved, discontinued 2
FDA once approved a drug with it for use in people. Those products are no longer sold.
Approved outside the US 6
A health regulator in another country approved it. FDA has not.
Supplement 18
Sold as a dietary supplement. FDA does not approve supplements before they are sold.
Cosmetic 3
Used as a cosmetic ingredient. FDA does not approve cosmetics before they are sold.
