Semaglutide example

A 5 mg vial with 2 mL of water is 2.50 mg/mL. A 0.25 mg dose is 0.10 mL, which reads as 10 units on a U-100 syringe, and the vial holds 20 doses. These are example numbers, change them to yours.

Questions

Semaglutide, frequently asked

How do I calculate a Semaglutide dose?

Divide the Semaglutide in the vial (mg) by the bacteriostatic water you added (mL) to get the strength in mg/mL. Divide your target dose by that strength to get the mL to draw, then multiply by 100 for the units on a U-100 syringe. For example, a 5 mg vial with 2 mL of water is 2.50 mg/mL, so a 0.25 mg dose is 0.10 mL, which is 10 units.

How much bacteriostatic water do I add to a Semaglutide vial?

That is your choice, and it only changes the strength, not how much Semaglutide you have. More water makes it weaker (more units per dose); less water makes it stronger. This tool shows the units for whatever amount you enter.

How many units of Semaglutide do I draw?

It depends on your vial strength and your dose. With the example above (5 mg in 2 mL, 0.25 mg dose) you would draw 10 units on a U-100 syringe. Enter your own numbers to see yours.

Is Semaglutide FDA approved?

It depends on the exact product. Some peptides and GLP-1 medicines are FDA approved and some are not. See our plain guide on what peptides are FDA approved.
