-23%TB-500 is a synthetic form of Thymosin Beta-4, a peptide that occurs naturally in the body and is made up of 43 amino acids. Its main job is to bind to actin — one of the key building-block proteins inside cells — which helps control how cells move, grow and repair themselves. That role makes it one of the most widely studied peptides in tissue-repair and blood-vessel research.
In animal studies, Thymosin Beta-4 has been researched for how it supports the growth of new blood vessels, helps cells migrate to where they’re needed, and influences the body’s response to inflammation and stress at a cellular level. It’s a popular reference compound for scientists studying recovery, repair and regeneration.
In preclinical animal studies, Thymosin Beta-4 has been investigated for:
TB-500 is often studied alongside BPC-157 in recovery and tissue-repair research, and the two are commonly investigated together in the BPC-157 & TB-500 research blend. Reconstitution for research use requires bacteriostatic water and syringes, also available as bacteriostatic water on its own.
≥99% purity, HPLC verified. Supplied as a lyophilised powder. Dispatched from the UK.

TB-500 is the synthetic form of Thymosin Beta-4, a peptide found naturally in most mammalian tissue. Because it binds to actin and helps regulate how cells move and organise themselves, it has become a widely used reference compound in laboratory studies of tissue repair and blood-vessel formation.
In preclinical animal models, researchers have studied Thymosin Beta-4 for its role in encouraging the growth of new blood vessels (angiogenesis), supporting cell migration, and influencing how tissue responds to inflammation and oxidative stress. Published work has examined these mechanisms in models of skin, connective tissue, cardiac and skeletal muscle research.
Its actin-binding activity is one of the most studied aspects of the peptide, and it is frequently used in regeneration and remodelling research alongside related compounds such as BPC-157.
