# BPC-157

> BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It has been studied in preclinical models for its apparent role in supporting tendon, ligament, muscle, and gastrointestinal tissue repair. Researchers have proposed that the peptide promotes local blood vessel formation and modulates growth factor pathways involved in tissue regeneration. Most available evidence comes from animal and in vitro studies, with human clinical data remaining limited. It is commonly discussed in research settings as an investigational tool for musculoskeletal and gut-related recovery.

- Also known as: Body Protection Compound-157
- Primary category: Healing & Recovery
- Effectiveness rank: #2 in Healing & Recovery; #5 in Anti-Inflammatory; #4 in Skin & Cosmetic
- Evidence level: Moderate evidence
- Route: Subcutaneous (Often injected near the site of injury; oral forms are discussed for gastrointestinal-focused research but are less common overall.)
- Dose range: 150-500 mcg
- Dose tiers: low 150 mcg; moderate 250 mcg; high 500 mcg
- Half-life: Estimated at under 4 hours based on limited pharmacokinetic data
- Timing: Morning, or split AM/PM
- Cycle: 2-4 weeks on, 2-4 weeks off (Cycling is commonly discussed to avoid theoretical receptor desensitization, though supporting data are limited.)
- Storage: Store lyophilized peptide refrigerated (2-8°C) or frozen; once reconstituted, keep refrigerated and use within 2-4 weeks.

## Mechanism of action

Laboratory research suggests BPC-157 may upregulate growth factor receptors, including those in the VEGF pathway, to stimulate angiogenesis at injury sites. Animal studies indicate it may also influence nitric oxide signaling and fibroblast activity, both linked to tissue remodeling. These combined actions are hypothesized to support reconstruction of damaged tendon, ligament, and mucosal tissue.

## Reported benefits

- Studied for accelerated tendon and ligament repair in animal models
- Investigated for gastrointestinal mucosal protection and ulcer healing
- Explored for muscle injury recovery support
- Reported anecdotally for joint discomfort reduction
- Studied for potential angiogenic effects supporting wound healing

## Reported side effects

- Injection site irritation or redness
- Headache
- Nausea
- Fatigue
- Limited long-term human safety data

## Common protocols

- 250 mcg once daily, subcutaneous, near the injury site, for 4 weeks

## Stacking notes

Often discussed alongside TB-500 in research contexts targeting combined soft-tissue repair.
