Methyltestosterone is an effective orally-taken form of the male sex hormone testosterone. In medicine, it is used for treating insufficient production of testosterone (does not stimulate the body for its production, but acts as its direct replacement) by men causing lack of spermatozoon, for example. By women, it is used for the treatment of breast cancer, mastodynia (pain on breast) and osteoporosis after menopause.
In case of the use of testosterone, only 5 – 10 % of the active substance is absorbed by blood, the rest is metabolised in the liver. The chemical structure of methyltestosterone is meant to cause, that the blood absorbs much higher parts of the administrated amount.
Methyltestosterone and its effects
Methyltestosterone has strong androgenic effects; it acts within very short time after the administration. It is used shortly before the performance is needed, for example before competitions. In bodybuilding, however, it is used in bulking cycles, as well. In case, that methyltestosterone is used alone, the muscles return to the previous state within short time after the use.
Methyltestosterone side effects
The use of methyltestosterone is connected with a lot of side effects. Amongst the most serious ones is the high toxicity of the product for the liver. It is caused by the mentioned chemical structure. There are also side effects that are typical for steroids with strong androgenic action – acne, loss of hair or increased aggression. What is more, methyltestosterone has a strong tendency to aromatize into estrogen, for this reason; there is a high risk of Gynecomastia. The product should certainly be used in a combination with antiestrogenic steroids. By women, methyltestosterone can cause a strong virilisation because of its strong androgenic action.
The maximal daily dose by men should not be higher than 25 mg. Because of its high toxicity, methyltestosterone should not be taken for more than four weeks. Women should avoid completely the use of the substance for the purpose of bodybuilding in order to prevent the risk of Gynecomastia.
