Frequently asked questions
How do I reconstitute tirzepatide?
Inject bacteriostatic water slowly into the lyophilized tirzepatide vial, directing the stream against the glass wall. Gently swirl — never shake — until fully dissolved. Typical reconstitution volumes range from 1 to 3 mL.
What is the standard tirzepatide dosing schedule?
Research protocols commonly start at 2.5 mg once weekly for four weeks, then increase to 5 mg weekly. Further escalation to 7.5 mg, 10 mg, 12.5 mg, or 15 mg may follow at four-week intervals based on response and tolerability.
How should reconstituted tirzepatide be stored?
Store reconstituted tirzepatide refrigerated at 2-8°C (36-46°F). It is generally stable for up to 28 days when stored properly. Do not freeze reconstituted solution.
