I tell you what I like them. I've ran through most of them. I'll run one brand for a few weeks then switch it up. I do t want my body to get used to the effects. The 3 that I'm playing with now are
*MP assault- crazy energy good pump but feels like pins in your hands with your hair crawls.
*C-4- good energy burst, great pump with just as crazy tingly feeling.
*AC/G3- good enery burst, way less tingly feeling, dam good pumps.
