About Tirzepatide
Tirzepatide (research code LY3298176) is a synthetic 39-amino-acid peptide that acts at the GIP and GLP-1 receptors. Biogenesis Labs supplies tirzepatide as lyophilized powder in 30 mg vials, for laboratory research use only.
Research-grade vials: Tirzepatide 30 mg. Every batch is independently tested — see the Certificates of Analysis.
How to calculate Tirzepatide concentration
concentration (mg/mL) = tirzepatide in vial (mg) ÷ diluent volume (mL)
- A 30 mg Tirzepatide vial with 2 mL of bacteriostatic water is 15.00 mg/mL (15,000 mcg/mL).
- On a U-100 syringe, 100 units = 1 mL, so each unit holds 150.0 mcg.
- Use 3 mL instead and the same vial reads 10.00 mg/mL, or 100.0 mcg per unit. More diluent lowers the concentration; the tirzepatide in the vial does not change.
For U-40 syringes (40 units = 1 mL), divide mcg/mL by 40 instead of 100. The calculator above switches between both scales.

Tirzepatide 30 mg vial
| Diluent | Concentration | mcg / mL | Per U-100 unit | In 10 units | U-100 units per 1 mg |
|---|---|---|---|---|---|
| 1 mL | 30.00 mg/mL | 30,000 | 300.0 mcg | 3.00 mg | 3.33 |
| 1.5 mL | 20.00 mg/mL | 20,000 | 200.0 mcg | 2.00 mg | 5.00 |
| 2 mL | 15.00 mg/mL | 15,000 | 150.0 mcg | 1.50 mg | 6.67 |
| 2.5 mL | 12.00 mg/mL | 12,000 | 120.0 mcg | 1.20 mg | 8.33 |
| 3 mL | 10.00 mg/mL | 10,000 | 100.0 mcg | 1.00 mg | 10.00 |
| 4 mL | 7.50 mg/mL | 7,500 | 75.0 mcg | 0.75 mg | 13.33 |
| 5 mL | 6.00 mg/mL | 6,000 | 60.0 mcg | 0.60 mg | 16.67 |

Reconstituting and storing a Tirzepatide vial
Let the sealed vial reach room temperature, swab both stoppers, and run the diluent slowly down the inside wall of the vial rather than onto the powder. Swirl gently until dissolved — don't shake — and label the vial with the concentration and date. Reconstituted solutions are commonly kept refrigerated at 2–8 °C and protected from light.

Tirzepatide calculator FAQ
What concentration does a 30 mg Tirzepatide vial with 3 mL of bacteriostatic water give?
10.00 mg/mL (10,000 mcg/mL). On a U-100 syringe that is 100.0 mcg per unit, and 10 units hold 1.00 mg.
What concentration does a 30 mg Tirzepatide vial with 2 mL give?
15.00 mg/mL, or 150.0 mcg per unit on a U-100 syringe.
How many U-100 units contain 1 mg of Tirzepatide?
It depends on the concentration: units per mg = 100 ÷ concentration in mg/mL. At 10.00 mg/mL (30 mg in 3 mL) 1 mg is in 10.00 units; at 15.00 mg/mL (30 mg in 2 mL) it is in 6.67 units.
How much bacteriostatic water should be added to a Tirzepatide vial?
There is no single correct volume. The volume comes from your own research protocol; the calculator and chart show the concentration each volume produces. Only add a volume your vial can hold.
Does this work for 10 mg, 15 mg, 20 mg or 60 mg tirzepatide vials?
Yes. Tap the vial size or type any amount in the custom field. The concentration is always the vial mg divided by the mL of diluent, so a 60 mg vial with 3 mL reads 20 mg/mL.
Does this Tirzepatide calculator provide dosing guidance?
No. It performs concentration and unit-conversion math only. All Biogenesis Labs products are supplied for laboratory research use only and are not for human consumption.
