What You Need
- Tirzepatide vial (common strengths: 5 mg, 10 mg, 15 mg)
- Bacteriostatic water (BAC water)
- Insulin syringe (0.5 mL or 1 mL)
- Alcohol prep pads
Step-by-Step Instructions
Step 1: Swab vial tops. Clean both the tirzepatide vial and BAC water vial rubber stoppers with separate alcohol pads.
Step 2: Draw BAC water. The amount depends on your vial strength and desired dose. For a 10 mg vial, adding 1 mL of BAC water creates a 10 mg/mL concentration. Use our BAC water calculator for the exact amount based on your dose.
Step 3: Add to the vial. Inject the BAC water slowly down the side of the vial. Avoid direct contact with the powder.
Step 4: Dissolve gently. Roll the vial between your palms. Tirzepatide typically dissolves quickly. The solution should be clear and colorless.
Amounts Seen in Research
Tirzepatide research references often describe amounts near 2.5 mg per week, with some moving toward 5 mg in later weeks. These figures are reported for reference only and are not a recommendation. Always calculate your syringe units based on the concentration you created.
Storage
Refrigerate after reconstitution. Reconstituted tirzepatide is generally stable for approximately 21 days at 2 to 8 °C. Protect from light.
