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

The standard preset is to add 2 ml of bacteriostatic water to a 10 mg vial of Retatrutide. 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 Retatrutide amount to syringe units after reconstitution?

At a concentration of 5.00 mg/ml, a 2.0 mg amount of Retatrutide measures about 40.0 IU (0.400 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 Retatrutide last in the fridge?

Reconstituted Retatrutide in bacteriostatic water typically remains stable for 28 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 Retatrutide in 2ml water give?

10 mg of Retatrutide reconstituted in 2 ml of BAC water produces a concentration of 5.00 mg/ml, which equals 5000 mcg/ml. At 2000 mcg per draw, this vial yields roughly 5 full draws.

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

You can, but it is not recommended for vials drawn across multiple sessions. Sterile water has no benzyl alcohol preservative, so reconstituted Retatrutide must be used within 24 hours. BAC water allows the vial to last 28 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 Retatrutide

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

Standard Retatrutide Reconstitution Protocol

Add 2 ml of bacteriostatic water to a 10 mg vial of Retatrutide. This gives a concentration of 5.00 mg/ml. A 2000 mcg amount measures about 40.0 IU on a U-100 syringe scale. Store refrigerated at 2–8°C and use within 28 days.

Retatrutide Reconstitution Chart

Common syringe draws at the standard Retatrutide 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 (Retatrutide)
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 Retatrutide

1

Gather your supplies

A sealed 10 mg vial of Retatrutide, 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 Retatrutide 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 Retatrutide fully dissolves. Do not shake. The solution should become clear.
4

Calculate the amount

At a concentration of 5.00 mg/ml, a 2000 mcg (2.000 mg) amount equals about 40.0 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 28 days.
