Semaglutide calculator FAQ

How do I use the Semaglutide calculator?+

Confirm your vial size in mg (default 5), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Semaglutide reconstitution?+

Most Semaglutide research protocols reconstitute a 5 mg vial with 2 mL of bacteriostatic water, yielding 2500 mcg/mL.

What syringe should I use for Semaglutide?+

U-100 insulin syringes are standard for Semaglutide subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Semaglutide calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
