TB-500 (Thymosin Beta-4) by Dragon Pharma

TB-500 is Dragon Pharma's formulation of a synthetic fragment of Thymosin Beta-4 at 5mg per vial — a naturally occurring peptide involved in cell migration, tissue repair and reducing inflammation throughout the body. Unlike localised peptides, TB-500 works systemically, supporting recovery across multiple tissue types regardless of injection location.

What Is TB-500?

TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein found throughout the body's tissues and involved in actin regulation — a process central to cell movement and tissue repair. By promoting cell migration to damaged areas, TB-500 supports the body's natural repair processes across tendons, ligaments, muscle and skin. Its systemic action means it works throughout the body from a single injection, rather than being concentrated at the injection site.

Effects and Benefits

• Systemic tissue repair support across tendons, ligaments, muscle and skin
• Anti-inflammatory effects that may support recovery from training-related strain
• Improved flexibility reported by some users over the course of a protocol
• Works throughout the body regardless of injection site, unlike localised peptides
• No suppression of natural testosterone — does not require Post Cycle Therapy

Dosage and Administration

TB-500 is typically used with an initial loading phase of twice-weekly injections for 4-6 weeks, followed by a maintenance phase of once-weekly dosing if continued support is desired. Unlike BPC-157, injection site location is less critical for TB-500 due to its systemic mechanism — subcutaneous injection anywhere convenient is generally considered effective.
