Mariusz Wach probably used tainted dietary supplements

It was reported by the German newspaper Bild that the polish boxer Mariusz Wach failed drug testing. This person tested positive for anabolic steroids. The drug testing was conducted before the fight between this sportsman and the Ukrainian boxer Vladimir Klichko.
According to A-sample of Mariusz Wach, he applied steroids. Results of his B-sample are not known yet.
It is necessary to note that the German newspaper Bild announced about the steroid positive of the polish boxer before it was done by the German Boxing Federation. Mariusz Kolodziej, the promoter of the boxer Wach thinks that it manifests that the German Boxing Federation doesn’t do its job appropriately. It lacks professionalism entirely.
What did Mariusz Wach affirm in order to defend himself? In fact, Mariusz Wach didn’t try to defend himself. The athlete only claimed that he had never applied any steroids or other banned drugs intentionally. The sportsperson even said that he didn’t know what he actually administered. He cared just about trainings and suitable diets. As for supplements, they were chosen and provided by his trainers. The polish boxer trusted his trainers entirely. He didn’t even ask which supplements were administered by him. He decided to put the total responsibility related to dietary supplements on his trainers and he was not interested in the nature of products that were given by his trainers.
Mariusz Wach didn’t desire to accuse his trainers of his steroid positive. He only disclosed the reality.
Thus, it is possible to suppose that Mariusz Wach has applied a tainted supplement. You know, it happens often that athletes apply nutrition supplements that turn out to contain steroidal compounds. Thus, problems begin.
If Mariusz Wach’s B-sample shows that he has administered banned medicines, he will be probably banned for one year. He will also have to pay a fine.
