Well I knew the last few years using jacked, there is nothing natural about it. Nor is it dangerous for the general healthy population. People with heart problems and over 50 should not take it. The deaths are tragic. Though the cause of the deaths is unknown from what I read. They only know dmaa was present in those whom passed right? In the greater scope of things I think the pharm company is trying to control dmaa sales more than anything else. But, the supplement companies shouldn't false advertise either. If they indeed claim it is in its natural form on the bottle then they should have the natural stuff inside.
