Was just wondering how long it takes for a person running clen to shed some fat off and how many pounds after a 6wk cycle of 6000mcg's, assuming diet is in check as well. I started today at 80mcg's a day and havnt really noticed any kind of headaches shakes or even a major increase in my heart rate or temperature. Only thing that was different was i felt more fatigued during my workout which led to it being shorter.
