Ephedrine is supposed to last 6 hours. I do a max of 3 doses a day with caffeine and aspirin/yohimbine. 4 just seems unnecessarybump. Anyone do 4 doses a day?
I have a question i am gonna start my first eca stack tomorrow and I have been going through threads and I can't seem to find out if I should take this after breakfast pre workout or should I take on empty stomach and workout for best results. I have been doing a mix of lifting, then cardio but I want to do whats gonna see the best results. Any suggestions?
