Fluoxymesterone substance is precursor of methyltestosterone. Through its changes in the chemical structure, was made much more androgenic than testosterone. The anabolic component is only slightly pronounced. Based on its characteristics Fluoxym 10 is used mainly when the athlete is more interested in a strength build up rather than in a muscle gain. Powerlifters and weightlifters who must stay within a certain weight class often use this drug because they are primarily interested in a strength gain without adding body weight. In bodybuilding Fluoxym 10 is almost exclusively taken during preparation for a competition. Since its substance is strongly androgenic while at the same time aromatizing very poorly, this substance helps the athlete obtain an elevated androgen level while keeping the estrogen concentration low.
