How do you calculate peptide reconstitution concentration?

Divide the milligrams of lyophilized material in the vial by the milliliters of bacteriostatic water added. For example, 10 mg reconstituted with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL (5,000 mcg/mL). For laboratory research reference only.
