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
For bulking, go with a Nitrocut/Testofuel/Creatine. Nitrocut is a non-stimulant pre workout, Testofuel is a natural testosterone booster, and Creatine gives your muscles the power to push more weight. When it’s time to cut, switch out the creatine for a non-stimulant weight loss supplement. Try Quadralean .
