The only problem with this is that it is thymomodulin that helps with the immune sytem, whereas thymosin beta 4 helps repair damaged tissue.
i can see why the essendon apologists would say that he just had the names of his substances mixed up
of course, if he had them mixed up from the start then he has still given the players TB-4!
of course, if he has given them TB4 instead of thymomodulin and had fantastic results then he probably thinks it worked brilliantly and that he is a genius.
