If this isn't the right place for this, please relocate it. I take a pre workout stimulant called jack3d, which its main active ingredient is 1,3 dimethylamylamine. There have been reports of heart attacks etc due to this product. If you take it as suggested, there should be no issues unless u have a medical condition. So, the FDA cracked down and it was taken off the shelves for a while. I don't believe it had ever been FDA approved. So my question is...for those who understand chemistry well, is this truly harmful to me? It is a caffeine derivative. I weight lift and this stim helps with focus and energy mainly. If you all agree it is harmful then I will stop taking. But, when the FDA approves drugs like Viagra and the like...I have to wonder what its motive is for pushing to ban this product? This is the only pre workout stim that has this as an ingredient. It's strong but again, taken correctly..you should have no issues. Look forward to your thoughts on this and why the FDA got involved? Thanks! Please Register or Log in to view the hidden image!
