the working
- 10 mg ÷ 2 mL = 5 mg/mL
- 0.25 mg ÷ 5 mg/mL = 0.05 mL
- 0.05 mL × 100 = 5 units on a 0.3 mL U-100 syringe
- 10 mg ÷ 0.25 mg = 40 → 40 full draws
- $79.99 × 0.25 mg ÷ 10 mg = $2.00 per draw
If this is a prescription, the dose and volume on your pharmacy label take priority. Ask your pharmacist about any mismatch.

doses of Semaglutide used in research
FDA-approved as Wegovy (weight reduction, CV risk reduction, MASH) and Ozempic (type 2 diabetes); the Wegovy injection label titrates 0.25 mg to 2.4 mg once weekly over 16 weeks and allows up to 7.2 mg weekly for adult weight reduction. These are the amounts specific labels and studies used, linked to each source. They are references, not recommendations; a prescription label takes priority.

what the numbers mean · where they come from
terms and sources
- Label amount or measured amount. The calculator starts from the amount printed on the vial. A lot certificate’s measured content (net peptide content, in mg) can replace it for the vial that was tested. HPLC purity is a share of peak area, not a mass, so a purity-only correction is shown as an estimate. See HPLC, certificate of analysis and how to read a peptide COA.
- Concentration. Amount in the vial ÷ water added. Terms: reconstitution, bacteriostatic water, lyophilized.
- Syringe units. A volume: 0.01 mL per unit on a U-100 syringe, 0.025 mL on U-40. Units say nothing about the compound until the concentration is known.
- Cost per draw. Vial price × amount per draw ÷ vial amount, from the price per mg of a current offer. Offers come from the Semaglutide price comparison; certificates from the COA library.
Arithmetic only, on the numbers entered. Amounts from labels or trials are cited references, not recommendations; PeptideTech does not give personal use instructions and does not test products.
short answers
Semaglutide calculator questions
How much bacteriostatic water do I add to Semaglutide 10mg?
Any volume the vial holds; 2 mL gives 5 mg/mL, so 10 units on a U-100 syringe holds 500 mcg. More water makes each draw read more units. The table below shows 1–5 mL for every Semaglutide vial size on sale.
What changes the calculated concentration?
Only two inputs: the amount of Semaglutide in the vial and the water added. 10mg in 2 mL is 5 mg/mL; twice the water halves it, and the amount per draw then reads twice the units. A lot certificate's measured content replaces the label: LA Peptides's 5mg lot 1818 measured 5.82 mg, which in 2 mL is 2.91 mg/mL. HPLC purity is a share of peak area, not a measured mass, so it is shown only as an estimate.
How many units is 0.25 mg of Semaglutide?
With 10mg in 2 mL (5 mg/mL) it is 0.05 mL, or 5 units on a U-100 syringe; the vial holds 40 full draws.
What doses of Semaglutide were used in research?
FDA-approved as Wegovy (weight reduction, CV risk reduction, MASH) and Ozempic (type 2 diabetes); the Wegovy injection label titrates 0.25 mg to 2.4 mg once weekly over 16 weeks and allows up to 7.2 mg weekly for adult weight reduction. The table on this page lists 3 sources with amounts, schedules and links.
What does Semaglutide cost per mg?
The lowest current US price is $300.00 for 50mg at American Peptides (about $6.00 per mg, checked 2026-11-06). The calculator turns any vial price into cost per draw.
How much Semaglutide is really in the vial?
Lot certificates on file report measured content: for example LA Peptides's 5mg lot 1818 measured 5.82 mg at 99.85% purity. Use the certificate correction to calculate from the measured amount.
