How Reconstitution Works
Reconstitution is the process of mixing a lyophilized (freeze-dried) peptide powder with bacteriostatic water to create an injectable solution. The concentration depends on how much BAC water you add to the vial.
For a 25 mg vial of Retatrutide, the calculator works out the mg/ml concentration based on your BAC water volume, then converts your target dose (4 mg) into the exact number of units to draw on an insulin syringe.
