The real difference is that brand-name Wegovy is an FDA-approved, rigorously tested medication, while compounded semaglutide is an unapproved, custom-made product with no guarantee of safety, quality, or bioequivalence.
Although both contain semaglutide, they are not the same due to five critical distinctions:
| Difference | Brand-name Wegovy | Compounded Semaglutide |
|---|---|---|
| FDA Approval | ✅ Yes: Fully approved for chronic weight management [1][2] | ❌ No: Not FDA-approved; bypasses review for safety and efficacy [1][2] |
| Active Ingredient Form | Semaglutide base (the exact form approved by FDA) [1] | Often uses unapproved salt forms (e.g., semaglutide acetate or sodium) [1] |
| Ingredients & Formulation | Standardized formulation with tested inactive ingredients for stability [2] | May include added ingredients (e.g., vitamin B-6, B-12, L-carnitine) [1] |
| Manufacturing & Quality | Made in FDA-registered Novo Nordisk facilities with strict quality control [2] | Made by state-regulated pharmacies; quality varies by facility [1][2] |
| Clinical Testing | Extensively tested in clinical trials (up to 15%+ weight loss proven) [3] | Not tested in clinical trials; no evidence of safety or effectiveness [1][2] |
| Dosage Forms | Approved injectables (0.25–2.4 mg); oral Wegovy pending FDA approval [2][4] | Varies widely: injections, oral drops, pills, nasal sprays [1][4] |
Additional critical points:
- There are no FDA-approved generics of Wegovy yet; compounded versions are not "generic Wegovy" [4].
- Compounded semaglutide has not been tested for safety, effectiveness, or quality control, exposing patients to serious risks [1][7].
- Cost difference: Wegovy can cost $1,300+/month without insurance, while compounded versions range $150–$400/month [8].
Recommendation: For safe and effective weight loss, choose brand-name Wegovy (by Novo Nordisk) if accessible. If cost is a barrier, consult your doctor about insurance coverage, patient assistance programs, or approved alternatives like Ozempic (though dosed lower). Avoid compounded semaglutide unless you have no other option and understand the risks of unverified quality and safety.
