BPC-157 (5 mg Vial) Dosage Protocol

BPC-157 (Body Protection Compound 157) is a 15-amino-acid peptide derived from a protective sequence in human gastric juice. Preclinical research demonstrates wide-ranging effects on tendon, ligament, gut, and vascular healing. This page covers the 5 mg vial.

Dosing & Reconstitution Guide

Route: Subcutaneous  |  Frequency: Once or twice daily  |  Half-life: ~30 minutes (extended local effect)

Standard Approach (3 mL = 1.67 mg/mL)

Reconstituting with 3 mL bacteriostatic water produces a concentration of 1.67 mg/mL. Volume per dose changes with concentration; mg dose itself does not change between vial sizes.

Reconstitution Steps

  1. Wipe the vial stopper and BAC water vial with alcohol; let dry.
  2. Draw 3 mL of bacteriostatic water into a sterile syringe.
  3. Inject slowly down the inside glass wall of the peptide vial. Do not aim at the powder.
  4. Gently swirl until fully dissolved. Do not shake.
  5. Label with reconstitution date. Refrigerate at 2–8°C; use within 30 days.

Supplies Needed

Estimates for an 8-week and 12-week cycle at 600 mcg per dose, once or twice daily (14 doses/week).

Protocol Overview

BPC-157 is one of the few research-grade peptides with broad consensus protocols across the recovery community. The standard pattern is twice-daily dosing during an active healing window (4–8 weeks), tapering to once-daily maintenance if continued use is desired.

Most users see results within 2–4 weeks for soft-tissue injuries (tendinopathies, partial tears, post-surgical recovery). Gut-protection protocols (IBD, ulcer healing) often show effects faster — within 7–14 days.

Cycle length: 4–8 week loading cycles are standard. Some users run continuous low-dose maintenance for chronic conditions; others cycle 4-on, 4-off. There is no established long-term safety data, so cycling is the conservative default.

Local vs systemic: Subcutaneous injection close to the affected area is favored when feasible. For systemic protocols (gut, vascular), abdomen or thigh injection works fine.

Dosing Protocol

Three common protocol intensities:

Cycle structure: 4-week loading at standard dose for active injury → 4-week maintenance at light dose → 2-week break before re-loading if needed.

Timing: Morning and evening doses, ~12 hours apart. Pre-workout dosing for performance-related protocols. Local injection near injury when feasible.

Stacking: Commonly paired with TB-500 (Wolverine Blend) for connective-tissue protocols — each addresses different aspects of repair.

Oral protocol: BPC-157 is unusually stable in gastric acid; some research uses oral capsule for gut-specific protocols at 500 mcg twice daily.

Important Notes

⚠ Research Use Only: BPC-157 is investigational. Most evidence from rodent models. Use is research-grade only.

How This Works

BPC-157 is a synthetic 15-amino-acid sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) derived from a fragment of body-protection compound found in gastric juice. It survives gastric acid that would destroy most peptides.

Animal models show: VEGFR2 upregulation accelerating angiogenesis at injury sites; modulation of nitric-oxide signaling; promotion of fibroblast migration and tendon-cell outgrowth; anti-inflammatory effects via downregulation of pro-inflammatory cytokines. The compound also stabilizes the gut-brain axis through serotonergic and dopaminergic modulation.
