Vasoactive Intestinal Peptide
Also listed as VIP, Aviptadil.
Vasoactive intestinal peptide (VIP) is in FDA's 503A Category 1. FDA is still evaluating it and has said it does not intend to take action against a 503A pharmacy that compounds it against a patient-specific prescription while the interim policy's conditions are met. That is enforcement discretion, not a listing, and FDA can change it. VIP is not in any 503B category. Compounded VIP is not FDA-approved. FDA does not check the safety, effectiveness or quality of compounded drugs before they are sold.

What this status traces to.
FDA's 503A categories document (updated May 14, 2026) lists "Vasoactive Intestinal Peptide" in Category 1, bulk drug substances under evaluation. VIP does not appear in any category of FDA's 503B categories document (updated March 21, 2025). It is not on the 503A bulks list in 21 CFR 216.23. Category 1 is FDA's interim enforcement discretion, not a statutory pathway.

Context
A removal or a committee vote is not a listing.
Removal from FDA's Category 2 is not FDA approval and not a listing. FDA removed several peptides from its 503A Category 2 after their nominators withdrew the nominations, not because the substances were found safe: BPC-157, TB-500, MOTS-c, semax and epitalon among others (removal noticed April 15, 2026, effective after 7 days), and CJC-1295 and ipamorelin earlier (removal notice dated September 27, 2024). None was added to the 503A bulks list, so none has a compounding pathway today. A favorable vote by FDA's Pharmacy Compounding Advisory Committee is a recommendation, not a listing: nothing changes unless FDA publishes a final rule.
FDA advisory committee
FDA's Pharmacy Compounding Advisory Committee has not reviewed it.
