Ozempic vs Wegovy: same semaglutide, different labels
You'll get: Ozempic and Wegovy hold the same drug, semaglutide, but each has its own label, top dose and pen.
How Ozempic and Wegovy differ: approved uses, top dose, missed-dose rules, pen design, side effect rates and self-pay price, all taken from the two labels.

Wegovy vs compounded semaglutide: what is actually different
You'll get: Wegovy is FDA approved; compounded semaglutide is not, and you cannot treat one as a swap for the other.
An honest side-by-side from a site whose parent company dispenses compounded semaglutide: regulatory status, what was tested, how the dose is measured, what the label guarantees and a compounded vial does not, and where price fits.

Semaglutide titration planner: Ozempic, Wegovy and tablet schedules by date
You'll get: Titration, the planned step-up in dose every four weeks, is slow on purpose to limit gut side effects.
How the planner turns the label dose schedules for Ozempic, Wegovy and the pills into dated steps, what it refuses to do, and what your prescriber decides.
Guides
Compounded semaglutide units to mg: how the converter works
You'll get: A brand pen gives a fixed dose; a compounded vial makes you measure with a syringe, and that is where errors happen.
Why a compounded semaglutide vial needs arithmetic that a brand pen does not, how the converter turns a concentration and a prescribed dose into syringe units and the nearest mark, and the errors it is built to catch.
Guides
Missed a semaglutide dose? The label rules for Ozempic, Wegovy and the tablets
You'll get: Ozempic's rule is to take a missed dose within 5 days of the missed day, and after that to skip it.
The exact missed-dose text from the Ozempic, Wegovy injection and semaglutide tablet labels, why the two injection rules give different answers, and how the helper applies them to your clock.

Four products, one molecule, different rules
Ozempic and Wegovy are the same semaglutide in different pens with different label schedules, maximum doses and missed-dose rules. The tablets (Rybelsus, Ozempic tablets and Wegovy tablets) add a daily routine with a 30-minute fasting window. Compounded semaglutide is none of these: it is not FDA approved, not interchangeable with them, and comes in vials whose concentration changes from fill to fill. Every page on this site says which product it is talking about.
How the numbers are sourced
Label facts cite the FDA prescribing information by revision date and DailyMed set id. Trial results cite the PubMed id of the primary publication. Prices cite Novo Nordisk's own price sheet with the date we read it. If a number is not on this site, we could not verify it. Pages carry an updated date and change when the label, the price or the evidence does.
