First, testosterone undecanoate was developed in the 80s. According to studies, a steroid not change the state of liver enzymes, i.e., it is not toxic to the liver: the absorption from the digestive tract the active substance does not enter the bloodstream, and the lymph, and further, bypassing the liver (via lymph total flow) - in circulatory system. Restaver is a prohormone in UK, turning the body to the active metabolite of testosterone - dihydrotestosterone. It has no estrogenic activity (and thus - does not cause gynaecomastia) and does not undergo aromatisation. The oral form of testosterone does not cause major suppression of endogenous hormone levels, as athletes from the UK say. However, as practice shows, the steroid is sufficiently weak androgen.
