BPC-157 dosage calculator

The BPC-157 dosage calculator above converts a target dose into exact syringe units based on your vial size and how much bacteriostatic water you used to reconstitute it. BPC-157 is commonly sold in 2 mg, 5 mg, 10 mg vials. The calculator supports both U-100 and U-40 insulin syringes and flags draws that are too large for the syringe barrel or too small to measure accurately. A synthetic pentadecapeptide derived from a sequence found in human gastric juice, studied for tissue repair signaling mechanisms. Enter your target dose in the calculator above to see the exact number of units to draw.

BPC-157 and BPC peptides

BPC-157 is a Body Protection Compound (synthetic pentadecapeptide). A synthetic pentadecapeptide derived from a sequence found in human gastric juice, studied for tissue repair signaling mechanisms.

BPC-157 (Body Protection Compound) is a synthetic 15-amino-acid peptide derived from a partial sequence of a protein identified in human gastric juice. It has been studied in preclinical animal research for its effects on tissue repair, angiogenesis, and gastrointestinal healing, with published work exploring tendon, ligament, muscle, and gut injury models. Most of the existing research is from rodent studies; human clinical data remains limited. BPC-157 is not approved by the FDA for human use and has been flagged by the World Anti-Doping Agency (WADA) as a prohibited substance in sport. Research-grade BPC-157 sold by chemical supply companies is labeled for laboratory research purposes only.

How to reconstitute BPC-157

Research vendors commonly offer BPC-157 in 2 mg, 5 mg, and 10 mg lyophilized vials. A 5 mg vial reconstituted with 3 mL of bacteriostatic water yields approximately 1,667 mcg/mL.

Reconstituting BPC-157 is the same unit-conversion process used for any lyophilized peptide:

  1. Draw your chosen volume of bacteriostatic water into a syringe.
  2. Inject the bacteriostatic water slowly down the side of the BPC-157 vial — do not shoot it directly onto the powder.
  3. Swirl gently until the powder fully dissolves. Do not shake.
  4. Store the reconstituted vial refrigerated.
  5. To dose, calculate your draw volume: divide your target dose by the concentration (vial mg ÷ water mL = mg/mL). The calculator above does this automatically.

For BPC-157 specifically, 2 mg, 5 mg, 10 mg vials are common. A typical reconstitution adds 2 mL of bacteriostatic water, producing a concentration of 2.5 mg/mL for the 5 mg vial size.

BPC-157 half-life and storage

Published preclinical pharmacokinetic work reports a short plasma half-life on the order of a few hours, though effects measured in tissue-healing models often extend beyond the circulating half-life.

Lyophilized BPC-157 is generally stored refrigerated at 2–8 °C or frozen for longer-term storage. Published laboratory handling notes report that reconstituted solutions are typically kept refrigerated and protected from light.

Common BPC-157 dosing mistakes

Most BPC-157 draw errors are unit errors, not arithmetic errors: confusing mg with mcg (1 mg = 1,000 mcg), or reading a U-40 syringe with U-100 math — the same printed mark holds 2.5× the volume. Two more worth avoiding: leaving the vial unlabeled, so the concentration and reconstitution date are lost, and under-diluting to the point where the draw is under about one unit and can no longer be read accurately.

Each of these is covered in full in the guides: reconstitution math from first principles, U-100 vs U-40 syringes, storage and shelf life, and how to reconstitute peptides.
