Peptide reconstitution calculator

This calculator converts a vial strength and a volume of bacteriostatic water into a concentration in mg per ml, then shows the matching volume on a standard research syringe. It is laboratory arithmetic for handling research compounds, nothing more: it provides no protocol or instructions for human use.

Reconstitution examples

Example 1: 10 mg vial

Scenario: 10 mg lyophilised peptide, 250 mcg measurement
Reconstitution: Add 2 mL bacteriostatic water, 5 mg/mL
Measurement: 0.05 mL = 5 IU on a U-100 syringe

Example 2: 5 mg vial

Scenario: 5 mg lyophilised peptide, 500 mcg measurement
Reconstitution: Add 1 mL bacteriostatic water, 5 mg/mL
Measurement: 0.1 mL = 10 IU on a U-100 syringe
