Superdrol (called methasteron, and methyldrostanolone) is the name of the most popular and the well-known product to contain the 2a,17a-dimethyl-5a-androst-3-one-17b-ol (methyldrostanolone) steroid. Superdrol is probably the most effective and widely used oral anabolic steroid of the last decade. It is basically masteron lacking the ester chain. As an oral steroid, it is equipped with a c-17aa modification allowing it to survive the first pass through the liver.
As a steroid, superdrol provides very dry and hard gains that are really noticeable after about the second week of using the product. Gains of as much as 15lbs to 30lbs of muscle mass in a short 4 week cycle were very commonly reported by users. Gains in strength are also very noticeable, with most users reporting a 15% to 25% increase in their maximum lifts after using this drug for only a couple of short weeks.
Methasterone is a oral steroid with a 17aa group; thus, it is very liver toxic. Since it was sold over the counter for so many years, there are many reported instances of people abusing this steroid by staying on the drug for more than the recommended 4 to 6 weeks.
