Quick Pro-Tip

Using more water (3mL vs 1mL) makes it easier to measure smaller doses accurately because there are more units of liquid per dose.

How to use this calculator

Most peptides like BPC-157, TB-500, or Semaglutide come in "lyophilized" (freeze-dried) powder form. To use them, you must add a diluent, usually Bacteriostatic Water.

This engine performs the complex unit conversion from mass (mg) to micro-dosage (mcg), accounting for the mechanical calibration of your specific syringe.

BPC-157 5mg
TB-500 5mg / 10mg
Ipamorelin 2mg
CJC-1295 2mg / 5mg

Reconstitution FAQs

1 milligram (mg) is equal to 1,000 micrograms (mcg). Most peptides are purchased in mg (vial size) but dosed in mcg. Our calculator handles this conversion automatically to ensure your math is precise.
A standard U-100 insulin syringe contains 100 units per 1 milliliter (mL). A U-40 syringe contains 40 units per 1mL. It is critical to select the correct syringe type in the calculator above as it changes the physical "unit" mark you draw to.
The total amount of peptide (mg) in the vial stays the same, but the concentration (potency per mL) changes. If you add more water, you must inject a larger volume (more units) to get the same dosage.
