Semaglutide reconstitution calculator

Semaglutide is assayed as a lyophilized solid in five and ten milligram vials for research use. The documented schedule begins at 250 micrograms once weekly and escalates on a four-week cadence — 500 at week five, 1000 at week nine, 1700 at week seventeen, and 2400 micrograms from week twenty-one.

Because the opening doses are small, diluent volume deserves attention before the first draw: a five milligram vial with two millilitres of bacteriostatic water yields 2500 micrograms per millilitre, so the week-one amount reads ten units on a U-100 syringe. The tool recomputes concentration, draw and reading error for whatever vial and diluent combination you enter, and marks any figure that sits outside the published range.
