I will not say too much regarding this issue, as it has been higly debated lately. In my opinion, all research indicates that raising TESTOSTERONE to supraphysiological levels is more damaging and confusing to the body than consuming other testosterone DERIVATIVES--ALL steroids are testosterone DERIVATIVES.
Testosterone has MANY FUNCTIONS in the body OTHER than building muscle. Sometimes, as we can see, it is not wise to play around.
ALL steroids possess inherent risks. Some greater than others--this is true.
