How to Mix Tirzepatide: Step-by-Step Guide: A Microdosing Perspective
Microdose Take
This guide originally addresses GLP-1 medication users on standard weekly protocols. The same underlying biology applies to microdosing, but the practical specifics differ. We've preserved the original guidance below; throughout, microdose-specific notes appear where the standard recommendations diverge.
⚠️ Educational only: GLP-1s are prescription medications. Microdose protocols are user-developed and not FDA-approved. Consult your prescribing healthcare provider before adjusting any dosing schedule.
What You'll Need
- Tirzepatide vial — typically 5mg, 10mg, or 15mg
- Bacteriostatic water (BAC water) — never plain sterile water
- 3 mL reconstitution syringe with 21-23g, 1" needle
- 1 mL U100 insulin syringe (29-31g, 5/16" or 8mm needle) for daily injections
- Alcohol swabs
- Sharps container for safe needle disposal
How Much BAC Water for Tirzepatide?
For most users, 2 mL of bacteriostatic water works best because it produces clean unit math. Here's a quick reference for common tirzepatide vial sizes:
| Vial Size | BAC Water | Concentration | 2.5mg dose | 5mg dose |
|---|---|---|---|---|
| 5 mg | 2 mL | 2.5 mg/mL | 100 units | — |
| 10 mg | 2 mL | 5.0 mg/mL | 50 units | 100 units |
| 15 mg | 2 mL | 7.5 mg/mL | 33 units | 67 units |
| 10 mg | 1 mL | 10.0 mg/mL | 25 units | 50 units |
