Hello Everyone!! I am just curious about the negative sides of clen. I am trying to put on muscle right now-(five weeks into an 8 week cycle) but soon I will need to turn into a lean burning machine and wonder if clen will be safe for assisting? Problem: have read alot about negative sides of clen-enlarged organs in animals, decreases in endurance and strength. I'd like to give it a go-round-but wonder if anyone has seen anything negative from using??
