This type of nutritional supplement can be very dangerous. It seems that any gains that could be accrued by using it are far outweighed by the problems that it can cause in the human body. It seems far more prevalent to work a bit harder to get muscle mass and not have to worry about the systemic problems that can occur with using supplements such as these. We know that there are those who are impatient and will try anything that gives them an edge at getting what they want for their bodies. We just hope that they read all the information that is involved and consult with their physician before taking things such as this that are dangerous!
