How reconstitution works
Reconstitution is the process of adding bacteriostatic water (BAC water) to a lyophilized (freeze-dried) peptide vial to create an injectable solution.
The amount of BAC water you add determines the concentration of your solution, which determines how many units you need to draw on your syringe for a given dose.
More water = lower concentration = more units per dose (easier to measure small doses accurately). Less water = higher concentration = fewer units per dose (fewer injections to use the vial).
