Peptide Reconstitution Calculator

Concentration

conc = vial dose ÷ water volume

Example: 5 mg BPC-157 dissolved in 2 mL bacteriostatic water gives 5 mg / 2 mL = 2.5 mg/mL = 2,500 µg/mL.

Syringe units

1 unit = 0.01 mL on a U-100 insulin syringe

A U-100 syringe holds 100 units per mL. To deliver 250 µg from a 2,500 µg/mL solution: 250 ÷ (2,500 × 0.01) = 10 units.

Vial yield

aliquots per vial = recovered volume ÷ aliquot size

A 5 mg (5,000 µg) vial in 2 mL yields 40 × 50 µL aliquots of 125 µg each. \t\t\t\t\t\t\tOne vial, one dilution log, one documented batch — that is the traceability the COA chain expects.
