What is BPC-157?

BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a naturally occurring protein fragment found in gastric juice. It has been widely discussed in research settings for its potential role in tissue repair, recovery, and cellular signaling processes.

In research literature and online discussions, BPC-157 is commonly associated with topics such as soft-tissue recovery, tendon and ligament support, gut health, and inflammation response. Because peptides like BPC-157 are typically supplied as a lyophilized (freeze-dried) powder, they must be reconstituted with bacteriostatic water before being measured in a syringe.

After reconstitution, doses are often discussed in micrograms (mcg), which means users need to convert their desired mcg amount into the correct number of U-100 insulin syringe units. That conversion depends on three variables:

  • The total peptide amount in the vial (mg)
  • The amount of bacteriostatic water added (mL)
  • The desired dose per injection (mcg or mg)

The BPC-157 calculator on this page performs those conversions automatically, allowing you to determine the correct syringe draw amount in units and mL based on your inputs.

How to Use the BPC-157 Calculator

Use this BPC-157 reconstitution calculator to determine concentration and convert your desired dose into the exact number of U-100 insulin syringe units to draw.

Step 1: Choose Syringe Size

Select your U-100 syringe size (30, 50, or 100 units). U-100 means 100 units = 1 mL.

Step 2: Select Vial Amount

Choose the amount of BPC-157 in your vial (for example 5 mg or 10 mg). Use Other for custom values.

Step 3: Enter Water Added

Enter how many mL of bacteriostatic water you added. This determines concentration and changes the units needed per dose.

Step 4: Select Dose (mcg)

Choose your desired dose in mcg (or switch to mg). The calculator shows concentration, mcg per unit, and the exact syringe draw in units and mL.

Tip: If your calculated draw is under ~1 unit, it can be hard to measure accurately on a U-100 syringe.

BPC-157 Calculator FAQs

How do you reconstitute BPC-157?
Reconstitution typically means adding bacteriostatic water to a lyophilized vial to create a liquid solution. The amount of water you add determines the final concentration.
Why does the amount of bacteriostatic water change the number of units to draw?
Adding more water lowers the concentration (mcg per mL). Lower concentration means you’ll need to draw more syringe units to reach the same mcg dose.
What does U-100 mean on an insulin syringe?
U-100 means the syringe is marked so that 100 units equals 1 mL. For example, 10 units = 0.1 mL and 25 units = 0.25 mL.
Can this calculator convert mcg to units for BPC-157?
Yes. Enter your vial amount (mg), water added (mL), and desired dose (mcg). The calculator will show mcg per unit and the exact number of units to draw on a U-100 syringe.
Is this BPC-157 calculator medical advice?
No. This is a math and unit-conversion tool only and does not provide medical advice or dosing recommendations.
