Thymosin Beta-4 (TB-4)

Thymosin Beta-4, or TB-4, is a synthetic version of a peptide the body produces. The pharmacy dispenses it as a 15mg preservative-free lyophilized vial, compounded to order. Compounded medications are not FDA-approved, and it is prescribed only after a licensed provider reviews your history.
Pharmacy shipping: $20 added once per medication order.
About this treatment
Explore a peptide involved in tissue repair.
Thymosin beta-4 is a naturally occurring peptide involved in how cells move and respond to injury. Its role in repair biology has made it a focus of research into wound and tissue responses.
Understand its role in cell movement
Thymosin beta-4 interacts with actin, a protein that helps cells organize their structure and move. Scientists study this relationship to understand how cells reach damaged tissue and participate in the body's response to injury.
See why repair researchers are interested
Research has examined thymosin beta-4 in wound-related processes and in early human studies. The aim is to understand where its biology may be useful. Bring the specific injury or recovery concern you want to discuss so the conversation stays connected to your situation.
Build the discussion around your recovery
Your provider reviews your history, current treatment and the activities affected by your symptoms. A clear goal for comfort, movement or rehabilitation progress helps make follow-up useful and keeps your recovery plan grounded in day-to-day function.
Research and product information
Laboratory findings and early studies of specific thymosin beta-4 preparations do not establish recovery benefits for IAM's compounded injection. Full-length thymosin beta-4 and the TB-500 fragment are different ingredients. The compounded preparation is not FDA-approved.
