Semaglutide FAQ

How do you reconstitute Semaglutide?

Add 1 mL of bacteriostatic water to a 2 mg vial of Semaglutide, which gives a concentration of 2 mg/mL. Inject the water slowly down the vial wall and swirl gently — never shake.

What is a typical Semaglutide dose?

A typical research dose of Semaglutide is 0.25–2.5 mg, 1x per week, increasing every 4 weeks. This is educational information, not medical advice.

How many units of Semaglutide do I draw?

From a 2 mg vial reconstituted with 1 mL of bacteriostatic water, draw 12.5–125 units on a U-100 insulin syringe for a 0.25–2.5 mg dose.
