Methyldienolone is an oral steroid that was researched in the 1960s for possible medical use, but that was never actually introduced to the pharmaceutical market. Methyldienolone was actually sold over the counter as a dietary supplement for a short amount of time before being banned in early 2005. Methyldienolone may appear under the nomenclatures 17a-methyl-4,9-estradienolone or 17a-methyl-17b-hydroxyestra-4,9(10)dien-3-one.
Methyldienolone has an anabolic to androgenic ratio of 1000/200, showing it to be a very potent compound. It cannot convert to estrogen, but does have some progestational activity which can increase the negative effects of estrogen. With this progestational activity in mind, methyldienolone is typically used as a part of a cutting stack along with other compounds that have low estrogenic activity as opposed to being used as the “dry” component of a bulking cycle that includes compounds that do convert to estrogen. With methyldienolone one can expect significant gains in both muscle mass and strength in a short period of time.
Methyldienolone is a C-17 methylated steroid, making it orally bioavailable but causing it to place stress on the liver. The 4,9 double bonds of methyldienolone also serve to increase its resistance to liver metabolism but will increase its liver toxicity. Methyldienolone is more liver toxic than most other methylated steroids mg for mg, but this should balance out due to the low doses needed to see results. Due to its moderate progestational acitivity, there is some risk for gynecomastia when methyldienolone is stacked with compounds that can convert to estrogen, as this progestational activity may intensify the estrogenic side effects of the other steroids. Androgenic side effects should be low with methyldienolone, but as with any steroid they are still a possibility. In comparison to other steroids, the overall side effects of methyldienolone are fairly low.
As mentioned before, methyldienolone is very potent mg for mg in comparison to other steroids. Results can be seen using as little as 1 mg/day, and typical dosing range is 2-10 mg/day. Due to its liver toxicity, methyldienolone should probably not be used for cycles lasting longer than 8 weeks.
Though it was sold over the counter as a supplement fpr a short period of time, methyldienolone was included in the Anabolic steroid Control Act of 2004 and was banned as of January 20th, 2005. After the ban left over methyldienolone was sold on the black market for a while, but there is not likely to be much if any left at this point. Methyldienolone may be banned, but there are still many prohormone options that are still legally available over the counter. These prohormones will still deliver results without breaking the law.
