I don't know the legality of the these but I'll list them anyway. 1) NoDOZ - Simply the best 2-3 boost you can get on the market. Contains 100 mg of pure "off the the counter" "safe to use like coffee" caffeine. PLEASE take one tablet or you will get major adrenaline rush and may cause increased blood pressure and anxiety. It can be found in over the counter in all major pharmacies and convenience stores. 2) Red Line - This stuff is the real thing. A lot of fitness stores and gyms started carrying this stuff but now it has reached mainstream. Pretty solid boost of energy. Will keep you up for hours. I only use it when I workout or go to the gym. Do not drink more that one bottle or try at work or for recreational purpose unless you plan on burning a lot of calories with full cardio exercise. 3) Red Bull + Vodka - My "get your freak on" drink of choice. Gives you wiings! What else is there to say. Any party or club hopping tour is not complete without one of these. Taste good and gives you that feeling of being high without any substance abuse.
