BPC-157 (Body Protection Compound-157)

Category: Healing & Recovery. Status: Research compound.

A pentadecapeptide derived from human gastric juice that promotes wound healing and tissue repair. Demonstrates remarkable regenerative properties across multiple tissue types including tendon, muscle, and nervous system.

How it works

Upregulates growth factor expression including VEGF and promotes angiogenesis, modulates nitric oxide system, and interacts with the dopaminergic system.

Key facts

  • Molecular weight: 1419.53 Da
  • Half-life: ~4 hours
  • Bioavailability: Variable; oral and injectable forms available
  • Storage: Lyophilized: room temperature. Reconstituted: 2-8°C for up to 30 days.

Dosing overview

  • Typical dose: 250-500 mcg per dose
  • Frequency: 1-2x daily
  • Duration: 4-12 weeks
  • Route: Subcutaneous injection (or oral capsules)

Protocol notes

  • Most run 250-500 mcg once or twice daily, splitting AM/PM doses.
  • For a local injury, inject subcutaneously as close to the injury site as practical.
  • Systemic/gut issues are typically dosed oral or away from the site; healing protocols often run 2-4 weeks then reassess.
  • Many cycle 4-6 weeks on, then a break once the target tissue has recovered.

Reported benefits

  • Accelerated tendon and ligament healing
  • Gut lining protection and repair
  • Neuroprotective effects
  • Anti-inflammatory properties
  • Muscle tear recovery

Possible side effects

  • Mild nausea (oral)
  • Injection site irritation
  • Dizziness (rare)
  • Fatigue (rare)

Research

  • BPC 157 and its role in accelerating wound healing (2021): Demonstrated significant acceleration of cutaneous wound healing in rat models with enhanced angiogenesis.
  • Stable gastric pentadecapeptide BPC 157 in tendon healing (2019): Showed improved biomechanical properties of healing tendons compared to controls.

  • deep_science_dee rated it 5/5 - Injury recovery was noticeably faster: Started BPC-157 for a nagging tendon issue that was not responding to rest alone. Within about 2-3 weeks I noticed reduced pain during movement and better range of motion. By week 5-6 I was back to normal activity. No dramatic side effects. Some mild redness at the injection site occasionally and one day of fatigue early on. Otherwise very clean compound in my experience. My physical therapist commented that my progress seemed faster than expected for this type of injury. Cannot prove causation but the timeline matched up. I keep a vial on hand now for future recovery needs.
  • maintenance_matt rated it 5/5 - Chronic issue finally improving after 3 months: Ran BPC-157 through a recovery phase after pushing too hard in training. The difference versus my last recovery attempt without it was clear. Less downtime, less residual stiffness, and I bounced back to full training about 2 weeks sooner than I expected. Protocol was straightforward, daily injections in the AM. Mild injection site reactions a couple times, nothing major. No systemic side effects that I could identify. I am convinced this shortened my recovery meaningfully. The caveat is always sourcing and the fact that this is still a gray area legally and medically. Do your research and m
  • benchpr_evan rated it 5/5 - Tennis elbow better by week 4: Ran oral for the gut and subQ near a nagging tennis elbow. Elbow started easing around week 4 and recovery between training sessions is clearly faster. Injection is a little stingy but no real side effects. Quality matters a lot with this one, I only use tested vials.
  • swims_andre rated it 5/5 - Rotator cuff finally quieted down: Nagging rotator cuff that lingered for months. SubQ near the site, meaningful improvement by week 5-6 and I could sleep on that shoulder again. No side effects beyond mild site redness. It is not instant, treat it like a slow-build recovery tool and it delivers.
  • mobility_sean rated it 4/5 - Helped my Achilles but not side-effect free: It clearly helped my Achilles tendonitis over about eight weeks. But I also got hit with weird fatigue and some low mood a few days in that I did not expect from a healing peptide. Dropped the dose and it settled. Just know it is not automatically side-effect-free for everyone, bodies are different. Still glad I ran it.
  • skeptical_grant rated it 3/5 - Non-responder here, reporting the miss: Really wanted this to work for my knee and I got nothing. Ran a full 6-week cycle at 500mcg injected local, quality vendor with a COA. Zero change in pain or function. Maybe my injury is structural and beyond what a peptide can touch, maybe I am just a non-responder. Posting because this sub skews toward the success stories and the misses deserve airtime too.
