A Data-First Evidence Review\",\n  \"body\": \"## What's breaking down\\nTendons are dense connective tissues that transmit force from muscle to bone. They have limited blood supply and slow cellular turnover. In tendinopathy or after acute injury, the extracellular matrix breaks down faster than it repairs. Collagen fibers become disorganized, tenocytes (tendon cells) decrease in number or function, and inflammatory signals persist. This imbalance between degeneration and attempted repair leads to pain, reduced load tolerance, and prolonged recovery. Mechanical overload, repetitive strain, or age-related changes accelerate the process. Repair pathways that promote organized collagen deposition, new vessel growth into avascular areas, and fibroblast activity are the targets studied in peptide research.\\n\\n## How these fit together\\nBPC-157 and TB-500 are the two peptides most discussed for tendon applications. BPC-157 shows consistent effects on local angiogenesis and growth hormone receptor expression in tendon fibroblasts in animal models. TB-500 acts more on cell migration and actin dynamics systemically. If a reader explores both, the combination targets different layers: BPC-157 for vascular and collagen organization at the injury site, TB-500 for broader cell recruitment and reduced fibrosis. No data show one replaces the other; they address overlapping but non-identical steps in the repair cascade.\\n\\n## What the evidence actually shows\\nMost data come from rat models of Achilles tendon transection or overuse injury. In one classic study, rats with surgically cut Achilles tendons received BPC-157 and showed faster functional recovery, higher failure load, better stiffness, and more organized collagen compared with saline controls by day 14 (preclinical tier). Multiple similar rat experiments replicated improved biomechanical properties and histological healing.
