Bro, at this point I really have to say that i think that Ephedrine just cant be good or as harmless as people say. THere is just so much crap coming out about it. If you go to bed slightly hungry each night and eat clean, YOU WILL get the results you are looking for and with very close to the same results. Everyone including myself likes to get an edge and seek an elixer that will give it to them quicker, thats cool but I dont think that with this stuff it is as safe as they are trying to portray it. If you are artificially raising your heartrate and then further increasing wouldnt that logically place undue stress on it? What would be the longeterm strain? Probably the same thing that has been showing up in the news. Going to bed hungry will give you the results, that i know as I have done both more than once. Anyway, I hope this helps
