HEAD-TO-HEAD COMPARISON
Compound Semaglutide vs WegovySemaglutide vs Semaglutide
Verdict: Same active molecule (semaglutide). Wegovy is an FDA-approved finished drug product with consistent quality control. Compound Semaglutide is a compounded preparation; price is historically much lower, but 503A compounding has been restricted since the FDA declared the shortage resolved. Verify the compounding pharmacy's Certificate of Analysis if pursuing the compound route.

Who should pick which
- Pick Wegovy if the primary goal is weight management with an obesity-indicated label. Higher maintenance dose and stronger trial weight-loss data.
- Consider Compound Semaglutide only with a clinician's prescription and a verified Certificate of Analysis from the supplying pharmacy. Cost is meaningfully lower than Wegovy but supply has narrowed since FDA shortage resolution.
- Consider Compound Semaglutide for research / off-label use cases; titration completes in roughly 17 weeks.
- Consider Wegovy for chronic weight management use cases; titration completes in roughly 17 weeks.
Switching between the two
Because Compound Semaglutide and Wegovy share the same active molecule, transitioning between them is straightforward: align the new product's dose to your existing maintenance level, or step into it at the closest available pen strength. No washout is typically needed.
