Tirzepatide Reconstitution by Vial Size
Compound tirzepatide ships in lyophilized vials from 5 mg to 60 mg. The reconstitution math is identical across sizes, but the resulting concentration and syringe-unit math change dramatically. Here's the complete reference for every common vial size:
How to Reconstitute Tirzepatide 10mg
Most common vial size for new compound users. Standard recipe: 10 mg vial + 2 mL BAC water = 5 mg/mL.
- 2.5 mg dose = 0.5 mL = 50 units on U100 syringe
- 5 mg dose = 1.0 mL = 100 units (full 1 mL syringe)
- Doses per vial: 4 (at 2.5 mg) or 2 (at 5 mg)
How to Reconstitute Tirzepatide 15mg
Standard recipe: 15 mg vial + 3 mL BAC water = 5 mg/mL (clean math, identical concentration to a 10 mg/2 mL setup).
- 2.5 mg = 50 units · 5 mg = 100 units · 7.5 mg = 150 units (use 1.5 mL or split)
- Doses per vial: 6 (at 2.5 mg) or 3 (at 5 mg) or 2 (at 7.5 mg)
- Alternative: 15 mg + 1.5 mL = 10 mg/mL (more concentrated, smaller draws)
How to Reconstitute Tirzepatide 20mg
Standard recipe: 20 mg vial + 2 mL BAC water = 10 mg/mL (high concentration for users on ≥7.5 mg doses).
- 5 mg = 50 units · 7.5 mg = 75 units · 10 mg = 100 units
- Doses per vial: 4 (at 5 mg) or 2 (at 10 mg)
- Lower-dose users (2.5 mg) should use 4 mL BAC instead = 5 mg/mL for cleaner unit math
How to Reconstitute Tirzepatide 30mg
Common compound size. Standard recipe: 30 mg vial + 3 mL BAC water = 10 mg/mL.
- 5 mg = 50 units · 7.5 mg = 75 units · 10 mg = 100 units · 15 mg = 150 units (split needed)
- Doses per vial: 6 (at 5 mg) or 4 (at 7.5 mg) or 3 (at 10 mg) or 2 (at 15 mg)
- For 30 mg vials at maintenance dose (≤5 mg), increase BAC to 6 mL → 5 mg/mL for forgiving unit math
How to Reconstitute Tirzepatide 60mg
Largest common compound vial. Standard recipe: 60 mg vial + 3 mL BAC water = 20 mg/mL (very concentrated).
- 5 mg = 25 units · 10 mg = 50 units · 15 mg = 75 units
- Doses per vial: 12 (at 5 mg) or 6 (at 10 mg) or 4 (at 15 mg)
- At 20 mg/mL, every unit is 0.2 mg — small draw errors have outsized dose effects. Consider 6 mL BAC → 10 mg/mL for finer control.

All values are units on a 1 mL U100 insulin syringe (each unit = 0.01 mL). "—" means dose exceeds 100 units (split injection or use larger syringe).
Mixing Tirzepatide Powder: Common Mistakes
- Shooting BAC water directly onto powder. Aim the needle at the inside glass wall — let water trickle down. Direct impact denatures the peptide.
- Shaking instead of swirling. Tirzepatide foams aggressively when shaken; foam reduces potency by up to 50%. Swirl gently in slow circles for 30–60 seconds until clear.
- Reconstituting cold. Let the vial reach room temp first (15–30 min from fridge). Cold powder dissolves slowly and can leave undissolved particles.
- Wrong syringe for the dose. If the calculator shows units >100 (full 1 mL syringe), either dilute the vial more (more BAC water) or split the injection.
- Mixing two vials together. Never. Each vial reconstitutes independently to maintain sterility.
Frequently Asked Questions
How do I reconstitute a 10mg tirzepatide vial?
Standard recipe is 10mg vial plus 2 mL BAC water, producing 5 mg/mL. On a U100 syringe, 2.5 mg equals 50 units (0.5 mL) and 5 mg equals 100 units (full 1 mL syringe). One 10mg vial yields four 2.5 mg starter doses or two 5 mg maintenance doses.
How much BAC water do I add to a 30mg tirzepatide vial?
Standard mix is 30mg plus 3 mL BAC for 10 mg/mL, giving 50 units at 5 mg, 75 at 7.5 mg, and 100 at 10 mg. For maintenance users at or below 5 mg, doubling to 6 mL BAC produces a more forgiving 5 mg/mL with larger, easier-to-measure unit draws.
Why does my tirzepatide vial foam during reconstitution?
Tirzepatide foams aggressively when shaken or when BAC water is shot directly onto the powder. Foam can reduce potency by up to 50 percent. Aim the needle at the inside glass wall, let water trickle down, and swirl gently in slow circles for 30 to 60 seconds instead of shaking.
Should I let tirzepatide sit before injecting after mixing?
Yes. Allow the reconstituted vial to sit for 5 to 10 minutes before the first draw so any micro-foam settles and dissolution finishes. Cold powder also dissolves slowly, so let refrigerated vials warm to room temperature for 15 to 30 minutes before adding BAC water.
Can I mix two tirzepatide vials into one larger vial?
No. Never combine vials. Each vial reconstitutes independently to maintain sterility. Mixing creates additional puncture events on stoppers and introduces compounding contamination risk. If you need a larger working volume, increase the BAC water added to a single, larger lyophilized vial.
