Peptide & GLP-1 compounding status, tracked.
503A/503B eligibility, shortage-list history, and FDA enforcement actions for the compounds your pharmacy, clinic, or lab actually touches — updated as the rules change, not whenever someone gets around to a blog post.
Dataset last reviewed: 2026-10-04
Not legal advice. Every status on this page is our own reading of public FDA guidance, shortage listings, and committee materials — it has not been reviewed by an attorney and is not a legal determination. "Contested" means pharmacies and regulators publicly disagree, not that we're resolving the disagreement. Verify independently, and check with counsel, before relying on any entry here.

What each status means
Our reading of public sources, not a legal determination — see the notice above.
- Compoundable (503A)
- Based on public 503A guidance, a compounding pathway appears to exist with a valid, patient-specific prescription. The closest thing to a green light in this dataset — but that's our reading of public sources, not a legal opinion, so confirm with counsel before relying on it.
- Contested
- Our read of public sources: some pharmacies compound it under a legal theory — a differentiated-formulation argument, or in anticipation of a pending committee recommendation — that no court ruling or final FDA rule has settled either way. We're flagging this as actively debated, not as a green or red light. This is not a legal determination; verify independently before relying on it.
- Restricted
- Based on public FDA bulk-substance and shortage listings, it appears to be off the permitted bulk substances list, or a shortage-based exception has ended. That's our read that no established pathway currently applies — not a formal legal bar, and not a determination we're qualified to make. Confirm current status with FDA sources or counsel.
- No Legal Pathway
- Based on public FDA records, we don't see an approval or a shortage-list listing — both are usually preconditions for a 503A/503B exception. From what's publicly available, we don't find a compounding route under any formulation theory, but this is our reading of public sources, not legal advice.
- FDA-Approved (narrow carve-out)
- An FDA-approved commercial product appears to exist. Public guidance suggests compounding is limited to narrow carve-outs for an individual patient (a documented allergy, a needed dosage-form change) rather than open compounding for unapproved uses — again, our reading of public sources, not a legal opinion.
