Formula explained

What the calculator actually computes

1

Concentration

vial amount (mg) ÷ liquid volume (mL)

A 5 mg quantity in 2 mL is a mathematical concentration of 2.5 mg/mL.

2

Volume for an entered amount

entered amount (mg) ÷ concentration (mg/mL)

An entered amount of 0.25 mg at 2.5 mg/mL corresponds mathematically to 0.1 mL.

3

U-100 syringe conversion

volume (mL) × 100

On a correctly identified U-100 syringe, 0.1 mL corresponds to 10 unit markings. Other syringe types may use different markings.

Safety and regulatory context

What FDA says about BPC-157

BPC-157 is not a component of an FDA-approved drug. FDA states that compounded drugs containing BPC-157 may pose immunogenicity risks for certain routes and may involve peptide-related impurities and challenges characterizing the active ingredient.

FDA also says it has identified no or only limited safety information for proposed routes of administration and therefore lacks sufficient information to know whether BPC-157 would cause harm in humans.
