Theres a reason its not being used. It costs more than var and winny, but is no where near as strong.
Silabolin is an unusual steroid since its substance is a precursor of the female hormone progesterone. Technically it is a derivative of 19-nortestosterone. Silabolin is a very weak, oral steroid which is not very suitable for the buildup of strength and muscle mass. It is a steroid with a mostly anabolic effect that has only very low androgenic characteristics. Athletes who have taken Silabolin as their only steroid were mostly disappointed by its effect. In combination with steroids such as Winstrol, Parabolan, Masteron and Silabolin it leads to a high-quality muscle gain which remains after discontinuing the use of the product. Silabolin, however, is more a steroid for female athletes.
Virilization symptoms in dosages under 12-16 mg/day are rare and the fact that Silabolin is derived from the female hormone progesterone should also remove moral and ethical doubts. Since the tablets are not 17-alpha alkylated, liver toxicity is relatively low.
However, in high dosages and over long intervals of intake it is possible that certain liver values will increase. Silabolin aromatizes only slightly so that estrogenic-caused side effects are rarely expected. Athletes report minimal water retention. Some bodybuilders use Silabolin shortly before a championship since it slightly increases the blood pressure, resulting in a higher vascularity. Silabolin requires a relatively high daily dosage since the substance is very poorly absorbed by the steroid receptors in the muscle cell. Twenty or more tablets a day could have a certain effect but probably will also lead to several side effects. This is apart from the fact that such a large amount of tablets will cost the athlete quite a few dollars. You can turn this around as much as you like but malt athletes only profit from taking Silabolin if the daily dosage is at least 20 to 40 mg. Since Silabolin is as expensive as Oxandrolone and the Winstrol tablets but less effective, almost nobody shows interest in this compound. This is also the reason why it is rarely found on the black market. Due to its low demand there are no fakes.
