How to reconstitute retatrutide
See how to mix a Retatrutide vial with bacteriostatic water, one step at a time, and find the units in each dose after mixing.
- Available vial sizes
- 10 mg, 15 mg, 20 mg, 30 mg, 48 mg, 60 mg
- Adding water to 10 mg yields 5 mg/mL
- 2 mL
- Bac water once opened
- 28 days
Mixing Retatrutide step by step
- Wash your hands, then use an alcohol swab to wipe the rubber stopper on the peptide vial and the one on the bacteriostatic water.
- Put the water you chose into the syringe. With 2 mL of water, a 10 mg vial gives 5 mg per mL.
- Slide the needle through the stopper, holding it at a slight angle; let the water run slowly along the vial's inside wall.
- Gently roll the vial between your hands until the powder dissolves. Don't shake it.
- Label the vial with the mix date, then store it as your product or prescription directs.
- Figure out your dose in units, then draw to that line.

Your Retatrutide dose in units
What the label tells you
It isn't FDA-approved for use in people; it's sold as a research chemical. No FDA label means there are no official mixing instructions; follow what came with the product.
Questions people often ask
How much bacteriostatic water do I need for 10 mg of Retatrutide?
There's no one amount that's always right. Adding 2 mL gives 5 mg per mL; extra water makes each unit weaker and small doses easier to draw.
Can I mix Retatrutide with sterile water?
Because sterile water has no preservative and is for single use, a mixed vial drawn from over days usually has bacteriostatic water. See bacteriostatic vs sterile water.
What's the way to mix reta?
Reta is short for retatrutide, and the steps don't change. Let the water flow slowly along the side, then roll it; don't shake.
