GLP-1 APIs: read the status before you order.
We list semaglutide, tirzepatide and liraglutide with their current FDA status, and name the manufacturer for each lot on the quote.

Current FDA status
- A 503B currently has no bulk pathway for these three. Both shortages are resolved (tirzepatide Dec 19, 2024; semaglutide Feb 21, 2025). FDA proposed on May 1, 2026 not to add them to the 503B bulks list.
- We supply semaglutide as the base form only. FDA says the salt forms can't lawfully be used in compounding.
- GLP-1 APIs must come from a manufacturer on FDA's Import Alert 66-80 Green List.
- We don't source substances FDA has said can't lawfully be compounded.
