Compounded GLP-1
Where a compounded drug parts company with an FDA-approved one, where 503A parts company with 503B, and which accreditation programs tell them apart.
Definition
A GLP-1 prepared from bulk active ingredient by a 503A or 503B pharmacy rather than bought as the approved branded product. It is not an FDA-approved drug: no agency has reviewed that particular preparation for safety, effectiveness or manufacturing quality. This is what most sellers in this register are actually selling, and the legal ground under it narrowed sharply once the shortages closed in late 2024.
