About TB-500.
Also known as: Thymosin beta-4 fragment, TB4 fragment
TB-500 is a synthetic fragment of thymosin beta-4, a protein involved in cell structure and movement. Most of the research on it has been done in animal models.
Live Vital prescribes compounded TB-500, which a licensed pharmacy prepares for an individual patient. It is not FDA-approved and has not been evaluated by the FDA for safety, effectiveness or quality. It is available only after a medical intake and review by a licensed clinician, and only if the clinician determines it is appropriate for you.
How it works
Thymosin beta-4 binds actin, a protein cells use to move and change shape, and has been studied in animal research for its role in cell migration and tissue remodeling. Prescribed TB-500 is administered by subcutaneous injection on a schedule your clinician sets after your intake.
Who may be evaluated.
- Adults interested in a clinician-supervised recovery protocol
- Eligibility is determined by a licensed clinician after a medical intake
How treatment is managed.
Your clinician sets the dose and schedule after your intake and reviews it at regular check-ins. Outcomes vary by individual and are not guaranteed.
Dosing is not one-size-fits-all. Your clinician sets your dose and schedule after your medical intake, and adjusts it as treatment progresses.
