Semaglutide is a GLP-1 receptor agonist and the most clinically validated compound this calculator covers — large randomised trials, prescription products, the works. That cuts both ways: prescription labels titrate from 0.25 mg up to 2.4 mg weekly over months under medical supervision, and miscalculated doses of compounded GLP-1s have caused documented harm. Community protocols commonly report 250 mcg – 1 mg weekly, deliberately below the label's maintenance range — a reported figure, not a protocol. A 5 mg research vial arrives freeze-dried and must be reconstituted in bacteriostatic water before a syringe mark means anything. The table below shows each water volume's concentration; the calculator does the conversion.
Open the Semaglutide calculator →| Concentration | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 5 mg vial | 5,000 mcg/mL | 2,500 mcg/mL | 1,667 mcg/mL | 1,000 mcg/mL |
Concentration = vial contents ÷ water added. It is the same compound at every volume — more water only means a weaker solution, larger syringe marks that are easier to read, and a larger injection volume. On a standard U-100 insulin syringe, one unit is 0.01 mL at any barrel size.
