Some compounded 'semaglutide' is a salt form (semaglutide sodium or acetate) rather than the approved base. The FDA has flagged this because a salt form is not established as the same active ingredient. From a safety view, it means you may not be getting what the label word implies — verify the exact ingredient.
What you need to know
The safety concern with salt forms isn't only chemistry trivia. If the product isn't the approved base, then its identity, dosing equivalence, and behavior aren't guaranteed to match the semaglutide studied in trials or sold as Wegovy and Ozempic.
This compounds the units/concentration problem: a 'unit' of a salt-form solution may not represent the same amount of active drug as you'd expect, so both the ingredient and the concentration need confirming before any dose makes sense.
The action is direct: ask the dispensing pharmacy, in writing, whether the product is semaglutide base or a salt form, and treat evasiveness as a reason to walk away. Ingredient identity is not a detail — it's the whole product.
| Question | Why it matters |
|---|---|
| Base or salt form? | Salt forms aren't established as equivalent to the approved base |
| Concentration (mg/mL)? | Needed to compute any dose safely |
| Which pharmacy dispenses it? | Controls ingredient sourcing and quality |
| Is there a BUD on the label? | Bounds safe-use window |
- Whether it's semaglutide base or a sodium/acetate salt
- The concentration in mg/mL
- The dispensing pharmacy and its license
- That the label matches what you were told
