BPC-157 Accelerates Achilles Tendon Healing in Rats

Study Design

• Model: Rat Achilles tendon transection
• Groups: BPC-157 (10μg/kg and 10ng/kg) vs saline control
• Route: Intraperitoneal injection, once daily
• Endpoints: Functional recovery, biomechanical testing, histology

Key Findings

Functional Recovery

BPC-157-treated animals showed significantly improved walking patterns at days 7, 14, and 21 post-transection compared to controls.

Biomechanical Results

BPC-157 treatment led to significantly improved biomechanical properties compared to controls:

• Load to failure: Significantly increased
• Tendon cross-sectional area: Increased compared to baseline
• Collagen organization: Improved alignment and structure

Mechanism Findings

• VEGF expression increased at injury site
• Neovascularization enhanced in healing tendon
• Inflammatory markers reduced at injury site
• Both doses (10μg/kg and 10ng/kg) were effective

Limitations

• Animal study — no human data yet
• Short follow-up period
• Single injury model tested

Clinical Relevance

These results are consistent with BPC-157's angiogenic and anti-inflammatory effects observed in other tissue types. Human clinical trials are needed before clinical application.
