Quick answer · Community-reported standard
A 10 mg vial of BPC-157 reconstituted with 2 mL of bacteriostatic water yields a concentration of 5.00 mg/mL. At that concentration, a 250 mcg dose of BPC-157 equals 5 units on a U-100 insulin syringe (0.050 mL). BPC-157 is typically administered once daily via subcutaneous.
BPC-157 10 mg reconstitution and dosage: 1 mL vs 2 mL bac water
For a 10 mg vial of BPC-157, bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 10 mg vial.
| BAC water added | Concentration | Volume per 250 mcg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 10.00 mg/mL | 0.025 mL | 2.5 units |
| 2 mL | 5.00 mg/mL | 0.050 mL | 5 units |
BPC-157 dosage chart: per-injection to weekly total
Common BPC-157 protocol doses centered on the 250 mcg baseline (research range 250 mcg–500 mcg), with weekly totals at once daily frequency.
| Dose level | Per injection | Frequency | Weekly total |
|---|---|---|---|
| Lower | 0.13 mg | Once daily | 0.88 mg |
| Baseline | 0.25 mg | Once daily | 1.75 mg |
| Higher | 0.38 mg | Once daily | 2.63 mg |
| Upper range | 0.5 mg | Once daily | 3.5 mg |
Weekly totals assume consistent once daily dosing. Adjust the calculator below for your specific vial size and dose.

BPC-157 reconstitution & storage
Reconstitute with bacteriostatic water. Add water slowly to the side of the vial, allowing it to gently mix with the lyophilized powder. Do not shake vigorously. Typical reconstitution uses 1-2mL of bacteriostatic water per 5mg vial.
Lyophilized powder: Store at -20°C. Reconstituted solution: Store at 2-8°C (refrigerated) and use within 4 weeks. Protect from light.
BPC-157 dosing FAQ
How much bacteriostatic water should I add to a 10 mg vial of BPC-157?
The community standard is 2 mL of bacteriostatic water for a 10 mg BPC-157 vial. That gives a concentration of 5.00 mg/mL, so a 250 mcg dose is 5 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 10.00 mg/mL and halves the draw to 2.5 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 250 mcg dose of BPC-157?
On a standard U-100 insulin syringe, a 250 mcg dose of BPC-157 is 5 units when the 10 mg vial is reconstituted with 2 mL of bacteriostatic water (5.00 mg/mL). If you use 1 mL of bac water instead, draw 2.5 units (10.00 mg/mL).
What is the standard BPC-157 dose?
Community-reported protocols for BPC-157 typically use 250 mcg–500 mcg once daily via Subcutaneous. 250 mcg is a common starting dose. Most commonly reported protocol; injected near injury site when possible
How long does a vial of BPC-157 last at 250 mcg once daily?
A 10 mg vial of BPC-157 contains roughly 40 doses at 250 mcg per injection. At once daily dosing, that is approximately 40 days (about 6 weeks) of supply per vial. Reconstituted BPC-157 should generally be used within 28 days when refrigerated.
Where do you inject BPC-157?
BPC-157 is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdomen), Subcutaneous (thigh), Subcutaneous near injury site, Intramuscular (research settings). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for BPC-157?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like BPC-157 because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
