Calculation report

Peptide Purity Calculator

Adjust a dose for the actual HPLC purity on a certificate of analysis, instead of assuming 100% active compound.

Inputs

Result

Formula used

Actual pure peptide (mg) = Labeled amount (mg) × (Purity % ÷ 100)
Adjusted dose (mcg) = Desired effective dose (mcg) ÷ (Purity % ÷ 100)
Filler / impurity (%) = 100 − Purity %

Reference

Peptide Purity & Effective Dose Calculator

Account for purity % when calculating real, effective dose.

Inputs

Labeled amount (mg)

Purity (%)

Desired effective dose (mcg)

Result

Actual pure peptide — mg

Adjusted dose to inject — mcg

Filler / impurity — %
