How much bacteriostatic water do I add to 10mg of Tirzepatide?

The standard preset is to add 2 ml of bacteriostatic water to a 10 mg vial of Tirzepatide. This produces a concentration of 5.00 mg/ml (5000 mcg/ml). Adjust the water volume down if you want a more concentrated solution for smaller syringe volumes, or up if you prefer easier-to-read markings.

How do I convert a Tirzepatide amount to syringe units after reconstitution?

At a concentration of 5.00 mg/ml, a 2.5 mg amount of Tirzepatide measures about 50.0 IU (0.500 ml) on a U-100 syringe scale. Divide the amount by the concentration to get the volume in ml, then multiply by 100 to get units. These are reconstitution reference points only, not usage guidance.

How long does reconstituted Tirzepatide last in the fridge?

Reconstituted Tirzepatide in bacteriostatic water typically remains stable for 56 days refrigerated at 2–8°C (36–46°F). BAC water contains 0.9% benzyl alcohol as a preservative. Never freeze, never leave at room temperature, and discard if the solution becomes cloudy or discolored.

What concentration does 10mg Tirzepatide in 2ml water give?

10 mg of Tirzepatide reconstituted in 2 ml of BAC water produces a concentration of 5.00 mg/ml, which equals 5000 mcg/ml. At 2500 mcg per draw, this vial yields roughly 4 full draws.

Can I use sterile water instead of BAC water for Tirzepatide?

You can, but it is not recommended for vials drawn across multiple sessions. Sterile water has no benzyl alcohol preservative, so reconstituted Tirzepatide must be used within 24 hours. BAC water allows the vial to last 56 days refrigerated. Use sterile water only if you plan to finish the entire vial in a single session.

Is this a dosage calculator?

It calculates reconstitution and syringe-unit conversion for laboratory research. It does not recommend how much of any compound to use.

How do I read units on a U-100 syringe scale?

A U-100 syringe scale has 100 units per 1 ml, so each unit equals 0.01 ml. For example, at 5 mg/mL, 0.05 ml lines up with 5 units. Multiply any volume in ml by 100 to get units on a U-100 scale.

How to Reconstitute Tirzepatide

Pre-filled calculator with standard defaults for Tirzepatide: 10 mg vial in 2 ml BAC water.

Standard Tirzepatide Reconstitution Protocol

Add 2 ml of bacteriostatic water to a 10 mg vial of Tirzepatide. This gives a concentration of 5.00 mg/ml. A 2500 mcg amount measures about 50.0 IU on a U-100 syringe scale. Store refrigerated at 2–8°C and use within 56 days.

Tirzepatide Reconstitution Chart

Common syringe draws at the standard Tirzepatide preset (10 mg in 2 mL BAC water = 5.00 mg/mL). Units are on a U-100 syringe scale (100 units = 1 mL). For laboratory research reference only.

Syringe units (U-100)	Volume	Amount (Tirzepatide)
5 units	0.05 mL	250 mcg
10 units	0.10 mL	500 mcg
15 units	0.15 mL	750 mcg
20 units	0.20 mL	1.00 mg
25 units	0.25 mL	1.25 mg
30 units	0.30 mL	1.50 mg
40 units	0.40 mL	2.00 mg
50 units	0.50 mL	2.50 mg

Step-by-Step: How to Reconstitute Tirzepatide

1

Gather your supplies

A sealed 10 mg vial of Tirzepatide, a vial of bacteriostatic water, a 1 ml U-100 syringe, and an alcohol swab.
2

Add the water

Wipe both vial stoppers with alcohol. Draw 2 ml of BAC water into the syringe and release it slowly down the inside wall of the Tirzepatide vial. Never spray directly onto the powder — the force can damage the peptide.
3

Swirl gently

Gently swirl the vial in a circular motion until the Tirzepatide fully dissolves. Do not shake. The solution should become clear.
4

Calculate the amount

At a concentration of 5.00 mg/ml, a 2500 mcg (2.500 mg) amount equals about 50.0 IU on a U-100 syringe scale.
5

Draw and store

Draw the amount you need, then immediately return the vial to the refrigerator at 2–8°C. Use the reconstituted vial within 56 days.
