Thymosin alpha-1 is a 28-amino-acid peptide first isolated from the thymus in Allan Goldstein's lab. A synthetic version, thymalfasin (Zadaxin), is approved in a number of countries outside the U.S., in some for hepatitis B. It is not FDA-approved in the U.S., and compounded versions are not FDA-approved. It does not treat or prevent any disease. If your clinician prescribes it, a licensed U.S. pharmacy prepares it and your clinician confirms the form, dose and schedule.
