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.

Community reviews of BPC-157

Rated 4.5 out of 5 from 20 community reviews by ResearchSafe members.

  • 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.
  • trades_luis rated it 5/5 - A cut healed shockingly fast: Cut my hand badly at work and the wound closed up faster than anything I have experienced, that alone sold me it is biologically active. Been running it for a minor shoulder issue since, improvement is real but slow, not dramatic. Manage expectations, dose consistently, do not expect week-one magic. It is a marathon peptide, not a painkiller.
  • vo2max_jake rated it 4/5 - Patellar tendon improved, but slow: Patellar tendonitis improved over about eight weeks, injected local. It was gradual rather than dramatic and the injection site stung each time. I think product quality is the swing factor here, my first vial did nothing and a tested one worked. Worth it, just be patient and source carefully.
