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

The standard protocol 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.

What is the standard dose of Retatrutide after reconstitution?

A common Retatrutide research dose is 2.0 mg per administration. At a concentration of 5.00 mg/ml, this equals approximately 40.0 IU on a 100-unit insulin syringe (0.400 ml per dose). Always confirm your dose against your protocol — this is a starting reference only.

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. This vial yields roughly 5 full doses at 2000 mcg per administration.

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

You can, but it is not recommended for multi-dose vials. 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.

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 standard 2000 mcg dose equals about 40.0 IU on a 100-unit insulin syringe. Store refrigerated at 2–8°C and use within 28 days.

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 (100-unit) insulin syringe, and an alcohol swab.
2

Inject the water

Wipe both vial stoppers with alcohol. Draw 2 ml of BAC water into the syringe and inject 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 your dose

At a concentration of 5.00 mg/ml, a 2000 mcg (2.000 mg) dose equals about 40.0 IU on a 100-unit insulin syringe.
5

Draw and store

Draw your dose, perform the injection, and immediately return the vial to the refrigerator at 2–8°C. Use the reconstituted vial within 28 days.

These defaults reflect the most common community protocols for Retatrutide. Individual research protocols may differ. Always verify against your source and consult a qualified practitioner before any injection. BodyHackGuide publishes for research and educational purposes only.
