Peptide Reconstitution Concentration Calculator

This laboratory calculator converts the mass of lyophilized peptide in a vial and the volume of diluent added into a concentration in mg/mL and mcg/mL, and shows the volume of solution that contains a chosen target mass. It performs arithmetic only. For laboratory research use only. Not for human or veterinary use.

How the calculation works

  1. Concentration in mcg/mL: peptide mass in the vial (mg) multiplied by 1,000, then divided by diluent volume (mL).
  2. Concentration in mg/mL: that result divided by 1,000, or peptide mass (mg) divided by diluent volume (mL).
  3. Volume containing the target mass: target mass (mcg) divided by concentration (mcg/mL) equals mL of solution.

Worked example: a 5 mg vial reconstituted with 2 mL of diluent has a concentration of 2.5 mg/mL, or 2,500 mcg/mL. A target mass of 250 mcg is contained in 0.1 mL of that solution.

Frequently asked questions

How do I convert mg to mcg?

Multiply by 1,000. For example, 5 mg is 5,000 mcg and 0.25 mg is 250 mcg.

Does adding more diluent change the amount of peptide?

No. The total peptide mass in the vial stays the same. More diluent lowers the concentration, so the same target mass is contained in a larger volume of solution.

Is this calculator dosing advice?

No. It only does unit arithmetic for laboratory reconstitution. Explicit SARMs products are sold as reference material for research use only and are not for human or veterinary use.
