Thymosin Beta-4 (TB-4) — 10mg

Thymosin Beta-4 is the full-length, naturally occurring protein from which TB-500 is derived. It’s a 43-amino acid peptide found in virtually every cell in the human body and plays a central role in how cells move, repair themselves, and respond to injury. While TB-500 is the synthetic fragment most commonly used in research, TB-4 is the complete native protein — making it the original reference compound for this entire class of peptide research.

About TB-4
TB-4 works primarily by binding to actin — one of the most important structural proteins in the body. By regulating how actin behaves, TB-4 controls how cells move and reorganise themselves, which is fundamental to tissue repair, wound healing, and the body’s response to damage. It also plays a key role in reducing inflammation and stimulating the growth of new blood vessels, making it relevant across a wide range of research models.

Key Benefits:
• Full-length native protein — the complete, unmodified form of the Thymosin Beta-4 molecule for authentic signalling research
• Cell movement and repair — studied for how it controls cell migration and helps move repair cells to areas of tissue interest
• Reduces inflammation — researched for its ability to calm inflammatory responses across multiple tissue types
• Blood vessel formation — promotes the growth of new vasculature to support tissue healing and remodelling
• Muscle and connective tissue repair — widely studied across musculoskeletal, cardiac, and wound healing models
• Skin and wound healing — one of the most researched peptides for dermal repair and scar reduction models
• Heart tissue research — studied for its protective effects on cardiac muscle and its role in heart repair models
• Neuroprotection — emerging research into its role in protecting and repairing nerve tissue

Why TB-4 vs TB-500?
TB-500 is a fragment of TB-4 that contains the core actin-binding sequence. TB-4 is the full protein — it carries the complete range of biological signals and is used in research where the full native molecule is required rather than an isolated fragment. Both are valuable tools, but TB-4 gives researchers access to the complete signalling profile.
