peptides · Systemic tissue repair peptide

Moderate evidence

TB-500 is a synthetic fragment of Thymosin Beta-4 that regulates actin, a key structural protein in muscle and tissue. Unlike BPC-157's local action, it works systemically to improve circulation and support recovery.

⏱️ Timing & dosage for TB-500

Best time to take

Twice weekly (e.g. Monday/Thursday). Cycle 4-6 weeks, can continue at a lower maintenance dose. Often combined with BPC-157.

Suggested dose

2-5 mg per week total, split across 2 subQ injections

✅ Benefits of TB-500

  • Systemic tissue repair, not just at the injection site
  • Reduces chronic inflammation
  • Supports heart muscle repair and cardiovascular recovery
  • Improves blood flow and circulation
  • Speeds recovery from muscle injuries and surgeries

⚠️ Side effects & risks
