every day 30 min prior to a workout i take 1 aspirin 3 caffeine pills and 3 ephedra. If you buy several weight loss ,fat burning pills on the market (hydroxycut or ripped fuel) you will pay more in those pills then what i do with those 3 . Then you will say but are you mental using all of this and my reply would be no. i've been using this concoction for the last 6 years and i have no problem whatsover. this concoction will give you a thermogenesis effect and will help to give you strenght (increase of 5-10%) energy and stamina. several studies show it's good to take 1 aspirin daily cause it will help your heart because the blood will be less thick. the caffeine will make the heart pump faster and the ephedra will only allow your lungs to get in more air. so more air to the system is also more air to the blood wich is transported quicklier to the muscles and they also get more air. it gives a faster recuperation and you can have a heavier workload.
