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
Despite its obvious benefits and limited side effects authorities have not endorsed the commercial sale of Deca Durabolin as an over the counter drug. This is to stop the usage of this drug in sports and other body building competitions. There is also the fear of abuse and although this drug has been termed a ‘side effects’ friendly drug across many spheres, the authorities have enough evidence which suggests that overdosing on Deca Durabolin or administering a cheaper rehashed version can prove to be extremely disastrous on the user’s health and well being.
