Results are observable within two or three weeks. One can expect to gain as much as 25 pounds in about a month when on a cycle of this compound. Water retention is minimized to tone the muscle fibres. Methylstenbolone doesn’t combine with the progesterone receptor and won’t change over to an estrogenic metabolite when synthesized by the body. The degree of aromatization is almost 0. It is, however, advisable to keep on-cycle backing and have provisions for post cycle treatment.



It was developed by Antaeus Labs and released initially under the trade name “Ultradrol.”



Bulking: 15 to 20 pounds of lean muscle mass can be gained with a daily dosage of 15 mg for about a month.

Cutting: Over a 4-week period, users can expect to gain 6 pounds of lean muscle mass while bringing down the body fat % by 3%.

Re-comp: With a daily dosage of 15 mg of methylstenbolone for about a month, athletes say that they’ve been able to achieve a reduction of 2.2% body fat level while increasing 6 to 11 pounds of lean muscle.

In any case, it is important to keep a watch on the diet, fluid intake and genetics while cycling with this prohormone, since these elements can be the difference between above-average results and disappointment.
