4 questions about legal & regulatory.
There is no blanket legal category for “peptides.” Separate FDA-approved prescription products, lawful patient-specific compounding under applicable federal and state requirements, clinical-trial products, and research/grey-market products. A prescription or interim FDA category is not FDA approval.

Category 2 is a temporary FDA category for nominated bulk substances that may present significant safety concerns while the agency reviews them. It is not an approval, a final decision on the 503A bulks list or the same thing as an advisory committee review.

There was no blanket 2026 approval or legalization of popular peptides. Nomination, interim category placement, Pharmacy Compounding Advisory Committee review, FDA recommendation and a final bulks-list rule are separate steps. An advisory vote is nonbinding, and even final bulks-list status would not make a substance FDA-approved.

“For research only” does not authorize sale for human use, establish lawful prescribing or provide FDA review of safety, effectiveness or quality. A vial sold in the research market is not a medicine for patients.
