Unlike many anabolics, Test-600x has no side effects. However, if you take the illegal version of this supplement, you may suffer from a battery of side effects. Unlike many anabolics, the illegal form of this supplement is not toxic to the liver or kidneys. However, it still can cause some serious side effects. One of these is gynecomastia, which is the development of secondary female characteristics, especially breast tissue. This happens in illegal forms of this supplement because pure injected testosterone can be converted to estrogen by the body. Gynecomastia is often very embarrassing, and you can avoid it by taking Test-600x instead of its illegal counterparts.
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
