Supply and documentation built for compounding pharmacies.
US Wholesale Peptides supplies bulk active ingredients to 503A and 503B compounding pharmacies with the documentation workflows those designations require. Batch records, lot traceability, and licensed-buyer verification are built into every order — not assembled after the fact.
Every lot is third-party tested by HPLC and mass spectrometry before it enters the catalog. The COA is produced at that point and available before you order — so your review process doesn't stall waiting on paperwork.
