How it differs from 503A
The 503B framework permits qualifying outsourcing-facility compounding without patient-specific prescriptions, subject to its conditions. The 503A framework generally ties qualifying compounding to patient-specific prescriptions and has limited anticipatory allowances.
Not a research-supply credential
Research material is not compounded medication. A supplier should not borrow pharmacy or FDA-registration language to imply oversight it does not hold.
Scale's boundary
Scale is a B2B research supplier and fulfillment provider, not a pharmacy or clinical service. Its products are not for human use, and sterility is not tested.
