BPC-157: Reconstitution Math & Reference
Last updated
How do you reconstitute BPC-157?
BPC-157 reconstitution is arithmetic: divide the vial mass (mg) by the volume of bacteriostatic water added (ml) to get the concentration in mg/ml. A 5 mg vial with 2 ml BAC water yields 2.5 mg/ml. Drawing 10 units on a U-100 insulin syringe (0.1 ml) then delivers 250 mcg. Peptly computes this instantly with a visual draw indicator.
What is BPC-157?
BPC-157 is a synthetic pentadecapeptide — a 15-amino-acid fragment derived from a protective protein originally isolated from human gastric juice.
BPC-157 (Body Protection Compound-157) is studied in the peer-reviewed literature primarily in animal models exploring tissue healing, angiogenesis, and gastrointestinal mucosa protection. It has not been approved by the FDA for human use.
Common research storage formats are 5 mg or 10 mg lyophilized powder. Once reconstituted, most research protocols keep the solution refrigerated and use within 2-4 weeks.
Peptly stores this profile so users do not re-enter the vial size, BAC water, and target mass each time. Switching peptide cards never overwrites the saved reconstitution mix.
Reconstitution math — reference table
| Vial | BAC water | Concentration | Example dose | U-100 units |
|---|---|---|---|---|
| 5 mg | 1 ml | 5 mg/ml | 250 mcg | 5 units |
| 5 mg | 2 ml | 2.5 mg/ml | 250 mcg | 10 units |
| 5 mg | 3 ml | 1.67 mg/ml | 250 mcg | 15 units |
| 10 mg | 2 ml | 5 mg/ml | 500 mcg | 10 units |
| 10 mg | 3 ml | 3.33 mg/ml | 500 mcg | 15 units |
Storage and shelf-life
Most research protocols refrigerate reconstituted BPC-157 at 2–8 °C and use within 2–4 weeks. Lyophilized powder typically stores at −20 °C until reconstitution.

Frequently asked questions
What volume of bacteriostatic water should I add to a BPC-157 vial? +
There is no single correct volume — it depends on the dose you intend to draw and how many units you want per draw. Peptly lets you set a target dose and the app shows the unit count for any vial × water combination instantly.
Does the reconstitution math change between 5 mg and 10 mg BPC-157 vials? +
The math is identical — concentration equals vial mass divided by BAC water volume. A 10 mg vial in 2 ml gives 5 mg/ml; the same concentration as a 5 mg vial in 1 ml. Peptly tracks each vial separately so you do not mix them up.
Why does Peptly use U-100 syringes for unit counts? +
U-100 insulin syringes are the most common in research settings. 100 units = 1 ml, so each "unit" mark is 0.01 ml. Peptly also supports U-40 if you select it in Settings.
Can I save my reconstitution mix to reload later? +
Yes. In Peptly Pro, every reconstitution mix can be saved with a custom name and reloaded in one tap. The injection log tracks each shot against that saved mix.
Is BPC-157 approved for human use? +
No. BPC-157 is not FDA-approved for human use. It is studied primarily in animal models in peer-reviewed research. Peptly is a calculator and reference tool, not medical advice. Consult a licensed clinician for any health decision.
