BPC 157

BPC 157 is renowned for its cytoprotective (cell-protective) and regenerative properties. While its exact, comprehensive mechanism in humans is not fully understood, animal and in vitro studies suggest it works through several pathways:

• Promotes Angiogenesis: It encourages the formation of new blood vessels, a critical process for delivering oxygen and nutrients to damaged tissues, which is essential for wound and tissue healing.
• Modulates Growth Factors: It has been shown to upregulate the expression of the Growth Hormone Receptor in cells like tendon fibroblasts, potentially enhancing the proliferative and healing effects of growth hormone.
• Anti-Inflammatory Action: It helps modulate the nitric oxide (NO) system and inhibits various pro-inflammatory cytokines, which aids in reducing swelling and facilitating repair.
• Gastroprotection: Its original use was based on its ability to protect the gastrointestinal tract, demonstrating strong potential in preventing and healing ulcers, and mitigating damage caused by $\text{NSAIDs}$ (non-steroidal anti-inflammatory drugs).

Potential Therapeutic Applications (Preclinical)

• Healing of musculoskeletal injuries (tendon, ligament, muscle, bone).
• Gastrointestinal disorders (ulcers, inflammatory bowel disease).
• Neuroprotection and nerve regeneration.

Current Status and Warning

BPC 157 is categorized by the FDA as a substance for which there is insufficient information to assess its safety, and it cannot be legally compounded by commercial pharmacies for human use. Due to the lack of large-scale human clinical trial data, its safety profile, long-term effects, and optimal human dosing are unknown. Its use is prohibited in competitive sports globally.
