Testosterone Undecanoate is a long ester of testosterone, with all its anabolic and androgenic properties. Many people know that in the distant past, the natural human hormone testosterone was studied and then, on the basis of research, such esters of this hormone as: Propionate, Enanthate, Cypionate, Decanoate were synthesized. All of these esters have a different time of effect in the body. Basically, all of these esters are produced in the form of oil solutions, in other words, in an injectable form. But there is another ester, it is called Undecanoate, it was originally produced in tablets (better known as Andriol), but due to the short duration of its action in the body, pharmacists also brought out injectable forms.
Without delving into the medical aspect of using Testosterone Undecanoate in therapeutic practice, we note that it is actively used in bodybuilding and powerlifting to build muscle mass and in general for masculinization, which is expressed in the acquisition of a more athletic and masculine figure. This anabolic allows you to reduce the mass of adipose tissue and, at the same time, increase the body weight without increasing fat. It also stimulates the growth of bone tissue, which is especially important for huge muscle loadings in bodybuilding.
