Andriol is one of the few “fresh” steroids that have appeared in the 80s. Andriol holds a special place among other steroids. This is a revolutionary steroid: along with methyltestosterone, Andriol is the only oral preparation of testosterone. Andriol contains Testosterone Undecanoate – this active substance is absorbed through the intestines and enters the lymphatic system. That is to say, it does not affect liver function.
