Lol, it's funny the way Purus names their compounds. On the label, 1,3,7-trimethylxanthine is caffeine and 2-amino-4-methythexane is 1,3-dimethylamylamine (1,3-dmaa). Anyways, it is banned in several countries, and it was recently added on the World Anti-Doping Agency's prohibited list in 2010, meaning it's illegal to use it in certain professional sports. So that's where the heat is coming from. Don't know how this applies to the military, though.
BTW, just got a new tub of cherry limeade Muscle Marinade. I cannot wait until tomorrow's workout!
