Semaglutide is a molecule, not a product. You can get it three ways, and the question "is semaglutide good for weight loss" is really the question "which of these three am I buying, and what am I giving up".
| Route | What it is | Approved for weight? |
|---|---|---|
| Wegovy | Novo Nordisk's semaglutide, pen or tablet | Yes |
| Ozempic | Novo Nordisk's semaglutide, for diabetes | No, off-label |
| Compounded semaglutide | Same molecule, compounding pharmacy | Not FDA-approved at all |
General information, not medical advice. Whether semaglutide suits you is a decision for a licensed clinician who knows your history.
Wegovy is the one approved for it
If you want the version the FDA reviewed and approved for weight management, that is Wegovy. It is dosed for that purpose, climbing higher than Ozempic does, and the label is written around it:1
Administer WEGOVY injection once weekly, on the same day each week, at any time of day, with or without meals.
FDA label, via DailyMed
It is also now sold as a daily tablet as well as a weekly injection, and the tablet self-pays cheaper than the pen.
Ozempic is the same molecule, approved for something else
Novo's own words:2
For adults with type 2 diabetes, along with diet and exercise, to improve blood sugar.
Novo Nordisk
Taking it for weight is off-label. That is legal and extremely common, and it is a prescriber's call rather than a shopper's. The practical catch is that Ozempic's dose range tops out lower than Wegovy's, so the two are not interchangeable at the top of the ladder even though the molecule is identical.
Compounded is what most cash buyers actually take
This is the honest centre of the question, because it is where nearly everyone paying out of pocket ends up.
Compounded semaglutide is the same molecule prepared by a compounding pharmacy. It is not FDA-approved, meaning the finished product has not been reviewed for safety, effectiveness or manufacturing quality. The regulatory position has also moved recently, in the FDA's own words:3
For a state-licensed pharmacy or physician compounding, dispensing or distributing semaglutide injection products under section 503A of the FD&C Act, the period of enforcement discretion has ended.
FDA
The side effects are identical, because they belong to the molecule. What you are actually trading is regulatory oversight for price, and it is worth knowing that is the trade rather than believing the products are simply the same thing at two prices.
What each actually costs
The gap is the whole decision, so here it is live rather than typed into a sentence that would be wrong next month:
Against that, the manufacturer's own published self-pay ladder:
Injection or tablet, and what dose
Semaglutide for weight is usually a weekly injection. It goes into the abdomen, thigh or upper arm, and you rotate the site each dose. Wegovy is now sold as a daily tablet too, and the tablet self-pays cheaper than the pen.
Either way you climb to it. You do not start at the dose that does the work. The pen ladder runs 0.25, 0.5, 1, 1.7 and 2.4 mg, with a 7.2 mg strength above that.
On the brand, every one of those doses costs the same. Going up does not put your bill up. We set the ladder out step by step with what each rung costs.
Semaglutide against tirzepatide
There is a second molecule, tirzepatide, sold as Mounjaro and Zepbound. It beat semaglutide in the only trial that put them head to head: 20.2% mean body-weight loss at 72 weeks, against 13.7%.
That is a real result. It is also one input among several. The drug that works for you is the one you can tolerate and keep paying for.
How to choose, honestly
We rank on price. That does not make price the only thing that matters, and on this drug it is not:
- If you want the approved product, that is Wegovy, and the tablet is the cheaper form of it.
- If your insurance covers something, coverage beats every cash price on this page. What your insurer publishes is worth ten minutes.
- If you are paying cash and choosing compounded, the questions that matter before price are which pharmacy makes it and whether you can reach a clinician. We wrote those checks out in full.
- If a program is cheap because it is a long prepaid commitment, that is the trade, and it should be a knowing one.
