Is it bad for me to use a fat burner like ClenbutRX for a long time? It's just that I need to go to the gym at 5am and I need a stimulant. Someone told me that using fat burners for a long time will slow down your metabolism. True of false?
I asked this question in another thread about thermorexin, and if there was any reason to cycle it.
ulter responded that since there is no ephedrine in it there really is no reason to cycle it unless you want to take off a week to have a break from training or whatever.
despite what ulter said i would still rotate it because you could build up a tolerance to the other compounds within... then when you come off you might have some headaches from it... i know this is true for caffine though I am not so sure about the other ingredients...
