What is the difference between thymosin alpha 1 and thymalin?
Both are immune peptides from the thymus (a gland in the chest that trains immune cells), from different research traditions. Thymosin Alpha-1 is a single, clearly defined peptide, approved as Zadaxin in more than 30 countries, mainly for hepatitis. Thymalin is a preparation made from calf thymus. Doctors in the Soviet Union and Russia have used it since the 1980s, and it has its own separate medical writing, including a long-running study of death rates. Neither is FDA approved in the US.
