Reconstitution

Reconstitution is the process of dissolving a lyophilized (freeze-dried) peptide back into a liquid so it can be used. The diluent is commonly bacteriostatic water, added slowly down the side of the vial.

The amount of liquid added sets the concentration of the resulting solution — which is why a reconstitution calculator is used to work out the math before pulling a draw. This is general laboratory-handling information, not dosing guidance.
