503A

On this site, 503A records that a company's own pages describe the pharmacy filling its prescriptions with that label.

A 503A pharmacy compounds a medication for one named patient against a prescription, under state pharmacy rules. Most compounded GLP-1s sold online come from one.

A company that names its pharmacy, or at least its category, tells you who is actually mixing what you inject. Each review below quotes where the company says it.

Every review that uses it

Each line is the sentence the word appears in, taken from our review of that company, with the full review a click away.

7 of the 298 reviews above use the word only inside a passage too long to quote here in one piece. We would rather link the review than cut a sentence out of the middle of a quotation.
