Although I am usually not inclined to posit speculations on why a particular drug does or doesn't do something, in this case I will. Im guessing that the higher doses of Anadrol cause enough appetite suppression (at least anecdotally) to make eating rather difficult. It can also increase insulin resistance and glucose intolerance (5). This has the effect of making macronutrient absorption more inefficient, and could also be a factor in reducing gains when the dosage goes over 100mgs/day. Unfortunately, Anadrol also has a reasonably profound effect on your body's natural hormonal system, on par with most other oral steroids , but not as bad as most injectables, and its certainly not as harsh on your lipid profile as many anabolics are
Many users have gained desirable results after use of Anadrol. Some have noticed considerable gain as soon as they started taking the steroid. Some others felt that there was lot of fat loss in the body while they gained lean and toned muscle mass. This made them look well sculpted rather than flabby as they looked before. Many body builders and weight lifters observed that they could lift much more weight than before taking the drug. There was a visible boost in their stamina, endurance and the time period for which they could continue lifting the weight.
