🧠 Key Notes

What makes it distinct

  • 01Studied alongside BPC-157 in recovery research models
  • 02Active fragment of Thymosin Beta-4
  • 03Investigated for systemic vs localised distribution

🧬 Mechanism of Action

How it works

TB-500 is the synthetic active region of Thymosin Beta-4, a naturally occurring 43-amino-acid peptide. Its primary biological action is binding G-actin and regulating actin polymerisation — the cytoskeletal process that drives cell migration. By upregulating actin expression and mobilising progenitor cells to sites of injury, TB-500 promotes coordinated repair across multiple tissue types. It also supports new blood-vessel formation (angiogenesis through VEGF signalling), reduces inflammation, and demonstrates systemic distribution after subcutaneous administration — making it a whole-body repair signal rather than a localised one.

✨ Documented Benefits

What the research shows it supports

B01Accelerates soft-tissue, tendon, and ligament repair in animal injury models.
B02Promotes angiogenesis, improving blood supply to healing or ischaemic tissue.
B03Supports cardiac tissue recovery in post-infarct research models.
B04Reduces inflammation at injury sites and supports balanced cytokine signalling.
B05Mobilises stem cells to damaged areas, supporting coordinated multi-tissue repair.
