Mibolerones is a potent anabolic steroid which is both higher affinity and more selective for the androgen receptor than metribolone.
The first step involves extending the conjugation of the enone function by an additional double bond. Chloranil (tetrachloroquinone) is the forerunner of dichlorodicyanoquinone (DDQ), a reagent used extensively for introducing additional unsaturation in the progestin and corticoid series. In the case at hand, heating acetate with chloranil gives the diene, and reaction of that compound with methylmagnesium bromide in the presence of cuprous chloride leads to addition of the methyl group to position 7 at the end of the conjugated system. The stereochemistry of the product again illustrates the preference for additions from the backside. The alcohol at C17 is then oxidized to a ketone. Enamines are commonly used to activate adjacent functions; they are also not infrequently used, as in this case, as protecting groups.
Thus, reaction of the intermediatewith pyrrolidine gives enamine. This transformation emphasizes the clear difference in reactivity between ketones at C7 and C17. A second methyl Grignard addition gives the corresponding 17a-methyl derivative. Hydrolysis of the enamine function then affords mibolerone.
In the athletic arena,the drug is used intermittently due to its high level of hepatotoxicity, with cycles usually lasting no more than 6 weeks followed by 6-8 weeks off. A daily dosage of 200 to 500mcg is most common for bodybuilding purposes. This level is typically sufficient for gains in strength and muscle mass (bulk). The high progestational and estrogenic activity of mibolerone makes it of little value in speed and endurance sports, causing an unwanted retention of water weight.
Mibolerone isgenerally not recommended for women for physique- or performance-enhancing purposes due to its very strong natureand tendency to produce virilizing side effects.
Dosages and uses:
Most athletes use about 5mgs about 30min prior to training or competition. It is not really "stacked" with anything except cardarine. It is usually used just prior to important training sessions or competitions. Many athletes already using heavy doses of steroids add in cheque drops as a pre-event enhancer.
