BPC-157 Dosage: Complete Protocol Guide (Oral vs Injection)
BPC-157 is one of the most widely researched recovery peptides available, with an extensive body of animal studies supporting its effects on tendon, muscle, gut, and nerve healing. This guide covers the two main administration routes — subcutaneous injection and oral — the dose ranges used in research, cycle structures, and how to choose the right approach for your specific application.
Research use only. BPC-157 has no FDA approval for human therapeutic use. All dosing information below is derived from animal studies and practitioner reports — not human clinical trials. Consult a medical professional before any self-administration decision.
The route you choose should be determined by your target application. BPC-157 is unusual among research peptides in that oral administration has genuine, documented utility — but only for gut-related applications. For any systemic or musculoskeletal application, injection is required.
| Aspect | Oral | Injection (SubQ) |
|---|---|---|
| Bioavailability | Partial — peptide partially survives gastric acid | Near-complete — bypasses digestive breakdown |
| Best application | Gut mucosal repair, IBD, leaky gut, ulcers | Tendon, muscle, ligament, bone, systemic, nerve |
| Dose required | 1,000–2,000 mcg/day | 200–500 mcg/injection |
| Ease of use | Simpler — dissolve in water and drink | Requires sterile technique and reconstitution |
| Pain/discomfort | None | Minimal with insulin syringe |
| Onset | Slower for gut effects (days to weeks) | May be faster for systemic tissue effects |
Dosage Protocols
The following protocols are based on doses used in animal model research, scaled to human weight equivalents, and informed by practitioner reports from the research community.
Injury Recovery (SubQ Injection)
Dose
200–500 mcg per injection
Frequency
Once or twice daily
Cycle length
4–12 weeks depending on injury severity
Timing
No strong timing requirement; some researchers dose morning and evening
Inject near the injury site when possible. Use the lower end of the range for minor injuries; higher end for chronic or severe tissue damage.
Gut Health / IBD (Oral)
Dose
1,000–2,000 mcg per day (1–2 mg)
Frequency
Once daily, split into two doses if desired
Cycle length
4–8 weeks
Timing
On an empty stomach for gut mucosal contact
Oral BPC-157 is primarily for gastrointestinal applications — it does not survive digestion well enough to produce systemic effects. For gut repair, this is the correct route; for tendon/muscle/systemic effects, injection is required.
Systemic Maintenance (SubQ)
Dose
200–250 mcg per injection
Frequency
Once daily
Cycle length
8 weeks on, 4 weeks off
Timing
Morning or pre-workout
Lower dose for ongoing maintenance and general tissue resilience rather than acute injury. A common approach for researchers who have completed a loading phase.
Some researchers use a two-phase approach, though this is based on practitioner convention rather than formal study design:
Loading Phase (Weeks 1–4)
Higher dose twice daily (400–500 mcg per injection) to establish tissue saturation during the most active healing window. Used when addressing an acute injury.
Maintenance Phase (Weeks 5–12)
Drop to 200–250 mcg once daily. Continue to support ongoing tissue remodelling without maintaining unnecessarily high plasma levels.
Off Cycle (4+ weeks)
Most researchers cycle off after 8–12 weeks. There is no published evidence of receptor downregulation or tolerance, but cycling is the standard conservative practice in the research community.
- BPC-157 lyophilised powder (typically 5mg vials) — source from a verified supplier with CoA
- Bacteriostatic water for reconstitution — not plain sterile water
- U-100 insulin syringes (1ml, 0.5" or 5/16" needle)
- Alcohol swabs for vial tops and injection site
