Shop for a GLP-1 online and you'll meet three categories that get blurred together on purpose: branded originals, compounded copies, and a newer wave of pills. They are not the same product at a different price — they differ in what's been tested, what's FDA-approved, and what can go wrong. Here's the plain-English version.
Branded originals (FDA-approved)
These are the name-brand medications from the two companies that developed them. Novo Nordisk makes semaglutide (Wegovy for weight loss, plus a Wegovy pill; Ozempic is the diabetes brand). Eli Lilly makes tirzepatide (Zepbound for weight loss; Mounjaro for diabetes). They're FDA-approved and backed by their own clinical trials, so quality and dosing are consistent. The trade-off is price: without insurance, injectable originals run several hundred dollars a month, though insurance or a maker savings card can change that a lot.
Compounded copies (not FDA-approved)
Compounded semaglutide or tirzepatide is mixed by a compounding pharmacy from the same active ingredient. It's usually the cheapest route, which is why most online cash-pay programs sell it — but it is not FDA-approved, has no trials of its own, and quality can vary by pharmacy. It was widely allowed during the 2022–2024 shortages; those ended, so it now sits in a legal gray zone, and the FDA has warned about dosing errors and unapproved versions. It's not a "generic" — no approved generic of Wegovy or Zepbound exists yet. Compounded can be a reasonable cash-pay option, but go in knowing what it is, and check the pharmacy (see below).
Pills and oral options
Oral GLP-1s are the newest wrinkle. There's an FDA-approved oral semaglutide, and Lilly's orforglipron (Foundayo) is a newer pill. Separately, many compounded programs sell oral drops, tablets or "gum" versions — those are compounded, not FDA-approved, and shouldn't be confused with the approved pills. If needles are the dealbreaker, a pill can be the thing that keeps you on treatment; just confirm whether the specific product is an approved original or a compounded preparation.
What to avoid entirely
Steer clear of "research peptides" — GLP-1-like compounds (for example, retatrutide) sold online "not for human use" with no prescription, often for $10–$35/mo. There's no clinical oversight, no quality guarantee, and real safety risk. If price is the problem, the answer is the cheapest legal option with a real clinician, not the gray market.
How to tell what you're actually getting
A legitimate program names its pharmacy and its type. A 503A pharmacy compounds per individual prescription; a 503B outsourcing facility makes larger batches under tighter FDA oversight. Either can be fine — but "we won't say" is a red flag. And in every case, a licensed clinician should review your intake and decide what's appropriate; the medication itself is never the whole story.
The short version
Branded = FDA-approved, consistent, pricier. Compounded = cheaper, not FDA-approved, quality varies by pharmacy. Pills come in both forms — check which. Our comparison chart labels every program FDA-approved or compounded, so you always know which lane you're in.
