On this site, 503B records that a company's own pages describe the pharmacy filling its prescriptions with that label.
As with 503A, it appears in a review only where the company uses the term itself, and a company that publishes neither label gets neither. The two labels are recorded separately because the companies use them separately.
The reviews below are the ones whose records carry the term, with the sentence it appears in.
Why this word has a page
10 of the 39 reviews published on this site use it. A word gets an entry here at 5, measured against the reviews' own text every time the site builds — so this page cannot outlive the usage that justified it.
Each line is the sentence the word appears in, taken from our review of that company, with the full review a click away.
Brello Health checked August 2026
What we could not find: we read the home page, both product pages, the FAQ, the states-we-operate-in page and the full terms and conditions on 2026-08-31, searching each for licensed, state, 503A, 503B, pharmacy, overseas and hours.
Zealthy checked August 2026
ShedRx checked August 2026
Gimme Care checked August 2026
What we could not find: across those six pages, searching for 503A, 503B and the names of pharmacies, no pharmacy is named — the phrasing is "licensed compounding pharmacies" and "U.S. pharmacies", and Gimme states "Gimme Care is not a pharmacy".
GoodGirlRx checked August 2026
Compounded semaglutide and tirzepatide by injection and as oral dissolving tablets, plus brand Ozempic, Wegovy, Zepbound and the Wegovy pill; compounded, in their words, "by licensed US pharmacies (503A & 503B)"

Ivy Rx checked August 2026
The microdose page says "Compounded in an FDA-registered U.S. pharmacy", the personalized page says "Medication is prepared in a state-licensed pharmacy", and the FAQ says the treatments are "compounded in pharmacies compliant with 503B/USP <797> standards".
Amble checked August 2026
Sourcing, from the same FAQ: "When prescribed, GLP-1 medications are dispensed by state-licensed, U.S. pharmacies. 503A pharmacies are licensed and regulated by state boards of pharmacy, while 503B outsourcing facilities are registered with FDA."

Lavender Sky Health checked August 2026
The pharmacy row names six pharmacies because Lavender Sky names them; we did not verify any of those pharmacies' own licensure or 503A/503B category, and this review makes no claim about either.
3 of the 10 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.
All 39 reviews are on the index, priced by molecule on the molecule pages. The rules every review follows are on how we review. Nothing on this page is medical advice — the disclaimer is here.
