What Is TB-500 (Thymosin Beta-4)?
Category: Peptide
A synthetic version of the naturally occurring 43-amino acid peptide Thymosin Beta-4. Works systemically to promote healing by upregulating actin and promoting cell migration.
Detailed Explanation
TB-500 is a synthetic peptide that replicates the active region of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino acid peptide found in virtually all human and animal cells. TB-500 promotes healing through several mechanisms: upregulating actin (a cell-building protein essential for migration and structure), promoting angiogenesis, reducing inflammation, and facilitating cell migration to injury sites. Unlike BPC-157 which is often used locally, TB-500 works systemically throughout the body.
Practical Context
TB-500 typically requires a loading phase of 4-6 weeks at 4-10mg per week (split into 2 doses), followed by a maintenance dose of 2-4mg weekly. It is commonly combined with BPC-157 for enhanced healing effects. TB-500 does not need to be injected near the injury site - its systemic action means it will find and promote healing wherever needed. It has been extensively studied in veterinary medicine, particularly for horse injuries.
Frequently Asked Questions
Do I need to inject TB-500 near the injury?
No, unlike BPC-157, TB-500 works systemically. You can inject it anywhere subcutaneously and it will travel through the body to promote healing wherever needed.
How does TB-500 differ from BPC-157?
TB-500 works systemically through actin upregulation and cell migration, while BPC-157 works more locally through angiogenesis and growth factor modulation. They complement each other and are frequently stacked together.

- Angiogenesis - The formation of new blood vessels from existing ones. Many healing peptides like BPC-157 promote angiogenesis to accelerate tissue repair by improving blood supply to damaged areas.
- Loading Phase - An initial period of higher dosing to achieve therapeutic levels quickly. Common with TB-500 (4-6 weeks of higher doses before transitioning to maintenance).
- Maintenance Dose - A lower dose used after the loading phase to sustain therapeutic levels. Typically 50-75% of the loading dose, taken less frequently.
