Superdrol is a powerful oral anabolic steroid derived from dihydrotestosterone. It’s structure is a relative of Drostanolone. The only difference – added a methyl radical in 17 alpha position, to increase the bioactivity when taken orally. These two drugs are very similar. Drostanolone and Methyldrostanolone does not aromatize, do not have estrogenic activity and have the same ratio of anabolic to androgen. Laboratory studies have shown that Methyldrostanolone has 4 times more powerful anabolic activity than Methyltestosterone and at the same time is only 20% androgen. It was in demand among athletes, due to its ability to increase the dry weight without water retention or fat gain.
