BPC-157 Dosage Calculator
Calculate reconstitution volumes and syringe units for BPC-157 research peptides
What does this BPC-157 dosage calculator calculate?
This BPC-157 dosage calculator converts the vial amount, liquid volume and an amount entered by the user into concentration and the corresponding volume. It performs unit-conversion arithmetic; it does not determine a safe or effective dose, administration schedule or suitability for human use.
Worked arithmetic example: 5 mg in 2 mL gives 2.5 mg/mL. An entered amount of 0.25 mg (250 mcg) therefore corresponds to 0.1 mL, or 10 units on a U-100 scale, where 100 units equals 1 mL. These are hypothetical calculation inputs, not a dosing recommendation. The calculator is for laboratory reference only, not human or veterinary use.

BPC-157 Dosage Questions
What is a common BPC-157 research dose?
Published research typically references 1-10 mcg per kilogram of body weight. The most commonly discussed research dose is 250mcg (0.25mg) to 500mcg (0.5mg) per administration. BPC-157 vials are most commonly available in 5mg and 10mg sizes. If you are shopping a 10mg vial, the current secra labs coupon code takes a verified 10% off — we saw $65.00 drop to $58.50 on August 16, 2026.
How much bacteriostatic water should I add to BPC-157?
For a 5mg BPC-157 vial, 2mL of bacteriostatic water is standard, giving a concentration of 2.5mg/mL (250mcg per 10 units). For a 10mg vial, 2-3mL is common. Use our Bac Water Calculator if you need help with reconstitution volumes.
What is BPC-157?
BPC-157 (Body Protection Compound-157) is a synthetic 15-amino acid peptide derived from a protective protein found in human gastric juice. It is available as a research compound and has been the subject of numerous preclinical studies. For a paired option, see our BPC-157 + TB-500 combo.
How do I read insulin syringe units?
Insulin syringes (100-unit, 1mL) are marked in units where 100 units = 1mL. Each unit equals 0.01mL. When the calculator says "draw to 10 units," fill the syringe to the 10-unit mark.
