Semaglutide Dosage Calculator
Semaglutide is supplied lyophilized in milligram vials, but research amounts are often small enough to be expressed in either milligrams or micrograms. Switch the dose unit below to whichever scale your documentation uses.

Small amounts favour more diluent
A 5 mg Semaglutide vial in 2 mL gives 2,500 mcg/mL, so a 250 mcg draw is 0.1 mL — 10 units. That is a workable but tight reading. Reconstituting the same vial in 5 mL gives 1,000 mcg/mL and moves the same 250 mcg to 25 units, where a half-graduation error is a much smaller share of the draw.
Micrograms versus milligrams
Documentation for GLP-1 class compounds mixes the two scales freely: 0.25 mg and 250 mcg are the same amount. This calculator accepts either — set the dose unit and the arithmetic adjusts. Always confirm which unit a figure is quoted in before entering it, since a factor-of-1,000 misread is the single most common calculation error in this category.
Handling notes
Introduce bacteriostatic water slowly down the vial wall, swirl until fully dissolved, and refrigerate. Do not shake. Ares Research publishes a batch-matched third-party certificate of analysis for every lot with HPLC purity and mass-spectrometry identity confirmation.
Frequently asked questions
How many units is 0.25 mg of Semaglutide?
+
0.25 mg is 250 mcg. With a 5 mg vial reconstituted in 2 mL, the concentration is 2,500 mcg/mL, so 250 mcg is 0.1 mL — 10 units on a U-100 insulin syringe. In 5 mL of diluent the same amount is 25 units.
How much bacteriostatic water for a 5 mg Semaglutide vial?
+
2 mL to 5 mL are all common. Because target amounts in this category are often in the low hundreds of micrograms, more diluent generally improves measurement accuracy by pushing the reading further along the barrel. The total peptide in the vial is unchanged either way.
How many doses are in a 5 mg Semaglutide vial?
+
A 5 mg vial contains 5,000 mcg, so it holds 20 draws at 250 mcg, 10 at 500 mcg, or 5 at 1 mg. Diluent volume does not change this count.
How should reconstituted material be stored?
+
Once reconstituted, most research peptides are held refrigerated at roughly 2–8°C, protected from light, in the original sealed vial. Bacteriostatic water contains 0.9% benzyl alcohol, which suppresses microbial growth in the diluent. Temperature, light exposure, and repeated freeze-thaw cycles all affect stability, so consult the compound-specific certificate of analysis and published stability data.
How do I read a U-100 insulin syringe?
+
A U-100 barrel is graduated in units where 100 units equal 1 mL, so each single-unit mark is 0.01 mL. To convert a volume in mL to units, multiply by 100 — 0.25 mL is 25 units. This calculator reports both figures so you can cross-check the mark against the volume.
