BPC-157 Dosage & Reconstitution Calculator
This BPC-157 reconstitution calculator converts vial mg + BAC water mL into concentration (mg/mL), draw amount (mL), and U‑100 units. Use it to double‑check mixing math, avoid mg vs mL mistakes, and keep measurements consistent across weeks. Enter your vial strength, how much BAC water you added, and your target dose in mg—then read the exact volume and syringe units to draw.

How to Use the BPC-157 Calculator
- Select vial strength: choose how many mg are in the vial (for example 5 mg).
- Select BAC water volume: choose how many mL you added.
- Select target dose: pick your desired dose in mg.
- Read the result: the calculator shows concentration (mg/mL) plus the draw amount in mL and U‑100 units.
U‑100 clarification: 100 units = 1.0 mL (so 10 units = 0.1 mL, 20 units = 0.2 mL).
How the reconstitution math works
The calculator uses simple unit conversions based on your vial strength (mg) and BAC water volume (mL):
- Concentration (mg/mL) = vial mg ÷ BAC water mL
- mL draw amount = dose (mg) ÷ concentration (mg/mL)
- U‑100 units = mL draw amount × 100
U‑100 tip: 100 units = 1.0 mL (so 10 units = 0.1 mL, 40 units = 0.4 mL).
Example BPC-157 calculation
Example inputs: 5 mg vial + 2 mL BAC + 0.25 mg target dose.
- Concentration: 5 mg ÷ 2 mL = 2.5 mg/mL
- Draw amount: 0.25 mg ÷ 2.5 mg/mL = 0.1 mL
- U‑100 units: 0.1 mL = 10 units
Example inputs are for demonstrating the math only. Always verify your vial label and your mix inputs.

Why Accurate BPC-157 Dosing Matters
After reconstitution, dosing becomes a conversion problem: you choose an amount in mg, but you inject a volume in mL (and often measure on a U‑100
syringe). Most errors come from mixing up mg vs mL, assuming the wrong concentration, or copying “units” from a different mix.
Converting the same way every time helps you stay consistent across days and weeks—especially when you’re planning protocols or tracking schedules.

Common BPC-157 Dosing Mistakes
- Mixing up mg and mL (they measure different things).
- Changing BAC water volume without recalculating the dose.
- Using the wrong syringe scale (U‑100 vs other syringes).
- Rounding too aggressively and drawing inconsistent volumes over time.
- Copying “units” from a different concentration/mix.

Frequently Asked Questions
What are U‑100 syringe units?
For U‑100 syringes, 100 units = 1.0 mL. That means 10 units is 0.1 mL, and 20 units is 0.2 mL.
Do I need to recalculate if I change the amount of water?
Yes. Changing BAC water changes the concentration (mg/mL), which changes the volume (mL) and units you draw for the same target mg dose.
What is BPC-157?
BPC‑157 is commonly discussed as a research peptide in recovery and tissue‑signaling conversations. This page does not provide dosing recommendations—only the mg ↔ mL ↔ units conversion math based on your mix.
Is BPC-157 sometimes listed in mcg instead of mg?
Yes—labels and protocols may use either unit. Convert carefully: 1000 mcg = 1 mg. This calculator expects the target dose in mg.
