I plan to start clen and thoroughly read the clen handbook. I am going to use 2 weeks on and 2 off. I have the taurine for my liver. What do I take during the 2 weeks off??? It says not to use effedra or yohimbie. What about the off weeks? I have animal cuts and do like them. Im resarching the animal cuts and they are lots of digestive enzimes. Would they be harmful? What else is im them that I should be aware of?
