How do you calculate peptide concentration after reconstitution?

The concentration formula is: Peptide Mass (mg) divided by Volume of Solvent (mL) equals Concentration (mg/mL). For example, reconstituting a 5mg peptide vial with 2mL of bacteriostatic water produces a concentration of 2.5 mg/mL or 2,500 mcg/mL. To determine the volume needed for a specific dose, divide your desired dose by the concentration. Remember that 1mg equals 1,000mcg when converting between units for accurate dosing calculations.
