TB-500

A synthetic version of a region of Thymosin Beta-4, a naturally occurring protein involved in cell migration and tissue repair, studied for recovery and flexibility.

What it is

TB-500 is a synthetic peptide based on an active region of Thymosin Beta-4, a protein your body produces that plays a role in building and repairing tissue. It's frequently paired with BPC-157 in recovery research.

How it's thought to work

Thymosin Beta-4 binds actin, a protein essential for cell structure and movement. By supporting cell migration, TB-500 is thought to help repair cells travel to injured areas and rebuild tissue. It has also been studied for encouraging new blood-vessel formation.

Potential health benefits

Preclinical work has explored TB-500 for:

Muscle, tendon and ligament recovery.
Improved flexibility and reduced stiffness in injury models.
Wound and tissue healing, including the heart in animal studies.

What the research says

Thymosin Beta-4 itself has a solid scientific literature, and TB-500 (its fragment) shows complementary effects in animal models. As with BPC-157, large controlled human trials are limited, so claims should be read as exploratory.

Considerations

TB-500 is a research compound and is not an approved medicine. The human evidence base is still developing; professional medical guidance is advised.
