Mastoral (Oral Masteron) by Alpha-Pharma is an oral steroid, its active ingredient is Methyldrostanolone.
Methyldrostanolone, also known as methasteron, is a powerful oral anabolic steroid that has never been sold as a prescription drug. In structure, this steroid is a close derivative of drostanolone (Masteron). The only difference in this case is the addition of a c-17 alpha-methyl group, a modification that provides the high oral bioavailability of Methyldrostanolone. However, the two agents remain very comparable. Both Methyldrostanolone and drostanolone are non-aromatizable, so there is no difference in the estrogenicity of these two steroids, and both steroids maintain a favorable anabolic ratio with androgens.
An effective Methyldrostanolone dosage for physical or performance-enhancing purposes appears to start in the range of 10-20 mg per day, taken for no more than 6 to 8 weeks. At this level it appears to impart a measurable muscle-building effect, which is usually accompanied by fat loss and increased definition. Don't expect to gain 30 pounds on this agent, but many do less than 10 pounds of solid muscle gain using this agent alone. In determining an optimal daily dosage, some find Methyldrostanolone to be measurably more effective when they venture up to the 30mg range. However, the potential hepatotoxicity should be considered with such use. To avoid further escalation of the liver, 20 mg per day of Metildrostanolone is sometimes stacked with a non-toxic injectable steroid, such as testosterone for the bulking phases or nandrolone or boldenone for more gain and lean tissue definition instead. by simply increasing the dosage Profile of the steroids. Methyldrostanolone also works well in cutting cycles, where its lack of estrogenicity is highly favored.
In the athletic arena, an effective oral daily dose would be reduced by about 2.5 mg per day, in cycles of no more than 4-6 weeks to minimize the possibility of virilization. The main point of contention with females is probably the dosage of 10mg per capsule, which is too high to use. The application would require the opening of each capsule and the subdivision of the powder content into 4 separate doses. As with all steroids, virilization is still possible.
Methyldrostanolone is not aromatized by the body and is not measurably estrogenic. An anti-estrogen is not needed when using this steroid, as gynecomastia shouldn't be a concern even among sensitive individuals. Since estrogen is the usual culprit of water retention, Methyldrostanolone instead produces a lean and quality appearance for the body without fear of excess subcutaneous fluid retention. This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major problems.
