TB-500 (Thymosin Beta-4)
A synthetic fragment of Thymosin Beta-4 widely used in injury recovery research and frequently stacked with BPC-157.
Overview
TB-500 is a synthetic peptide derived from Thymosin Beta-4, a protein naturally present in nearly every human cell. It is studied for its effects on cell migration, vascular development, and systemic healing, and is one of the most popular recovery compounds among athletes and biohackers.
Benefits
- Promotes cell migration to injury sites
- Supports muscle, tendon, and ligament repair
- May improve flexibility and reduce inflammation
- Frequently stacked with BPC-157 for synergistic recovery
Mechanism of Action
TB-500 binds and regulates actin, a key cellular building block, which promotes cell migration, angiogenesis, and tissue regeneration at sites of injury or stress.
Dosage (informational only)
- Typical range
- 2–10 mg per week
- Frequency
- 1–2x weekly during loading; reduced for maintenance
Often dosed with a higher loading phase followed by maintenance. Long-term human safety data is limited.
Side Effects
- Generally well-tolerated in studies
- Possible mild fatigue or head rush
- Local injection site reactions
