An anabolic steroid called GP Test U500 – Testosterone undecanoate is testosterone with tethered etheron with a very long PPD Undecanoate. The half-life of this preparation is very long, on the order of 16-17 days. Because of the large PPR, this injection can be done quite rarely. In bodybuilding, this drug is not popular. Its main purpose is the use during hormone replacement therapy.
Among the effects of the use of testosterone undecanoate are distinguished:
- moderate increase in muscle mass;
- increased motivation, mood and overall tone of the body;
- improved nitrogen balance;
- increase endurance (in view of stimulating the production of erythrocytes in the body weight and increasing the blood oxygen as a result).
It is important to note that testosterone undecanoate, which is only in the 80’s was established in the form of tablets (capsules), is safer for the body, as opposed to injecting its analogues (as lowers the level of endogenous testosterone and has a minimal effect flavor). However, the reverse side of this factor is less pronounced effect on oral preparation controls and power rates.
