Route

Subcutaneous injection

Half-Life

~7 days

Common Vials

5 mg

Reconstituted Stability

Up to 28 days refrigerated

Note: Always start at the lowest dose (0.25 mg/week) and titrate up slowly over 16+ weeks. Rapid dose increases significantly increase nausea and GI side effects. Do not skip titration steps.

Semaglutide Storage

Lyophilized: 2-8 C. Reconstituted: 2-8 C

Stability after reconstitution: Up to 28 days refrigerated. Always use bacteriostatic water for multi-use reconstitution. Label the vial with the reconstitution date and discard after the stability period. Use our peptide calculator above to determine the right amount of water to add.

Semaglutide Frequently Asked Questions

Standard titration: 0.25 mg/week for 4 weeks, 0.5 mg for 4 weeks, 1.0 mg for 4 weeks, 1.7 mg for 4 weeks, then 2.4 mg maintenance. Each step should last at least 4 weeks.

Adding 2 mL gives 2.5 mg/mL. For a 0.25 mg starting dose, draw 0.1 mL (10 units). For 0.5 mg, draw 0.2 mL (20 units). This makes the entire titration easy to calculate.

At the starting dose of 0.25 mg/week, a 5mg vial lasts 20 weeks. At 1 mg/week, it lasts 5 weeks. At 2.4 mg/week, it lasts about 2 weeks.

Nausea is the most common side effect and typically occurs when starting or increasing the dose. It usually improves within 1-2 weeks at each dose level. Eating smaller meals and avoiding high-fat foods helps.

Inject once weekly on the same day each week. There is no specific time of day requirement. If you miss a dose within 5 days of the scheduled day, take it as soon as possible. If more than 5 days late, skip that dose.

Yes, rotate injection sites between the abdomen, thigh, and upper arm. The abdomen typically provides the most consistent absorption. Always inject subcutaneously, not intramuscularly.
