GLP-1 comparison
Compounded vs Brand Semaglutide
The same molecule, prepared two very different ways. Compounded is a fraction of the cost. Brand — Wegovy and Ozempic — is FDA-approved, batch-tested, and backed by pivotal trials. Here is the honest trade-off.
Compounded
Lower cost, less oversight
~$150–$400/month. Same active molecule; often includes B12 or glycine. Multi-dose vial with an insulin syringe. Only legal while the FDA lists semaglutide as being in shortage.
Brand (Wegovy / Ozempic)
FDA-approved, trial-backed
~$1,000–$1,350/month list. Pre-filled pens with fixed dose steps. GMP manufacturing and full batch testing. Sometimes covered by insurance; savings cards available.
A note on safety.
The FDA has warned about serious dosing errors and adverse events with compounded GLP-1 products. If you use compounded semaglutide, source it from a licensed US 503A/503B pharmacy that publishes third-party lab testing, verify the vial concentration before every dose, and use the calculator on this hub to convert mg to insulin-syringe units precisely.

Draw the right units, every time
Compounded vials are drawn with an insulin syringe. One decimal place difference is a double or half dose. The GLP-1 Dose Calculator does the mg-to-units math from your prescribed dose and vial concentration.
Which one is right for you?
Cost is the deciding factor and you have no coverage
Compounded semaglutide from a reputable 503A pharmacy can be a fraction of the brand's list price. If insurance won't cover Wegovy and you cannot afford the out-of-pocket cost, compounded is the practical route — with informed consent on the trade-offs.
You want FDA oversight and trial-verified potency
Brand semaglutide is what STEP, SUSTAIN, and SELECT actually studied. Every batch is manufactured to GMP standards and released against FDA specifications. If regulatory rigor matters to you, take the brand.
You have partial insurance coverage
Coverage plus a manufacturer savings card can put the brand within striking distance of compounded pricing. Always check current copays before assuming the brand is out of reach.
You have cardiovascular disease
The SELECT trial evidence for reducing major cardiovascular events was on brand Wegovy specifically. That indication does not automatically transfer to compounded formulations. If CV benefit is the reason you are on semaglutide, the brand is the right choice.
