i am taking it to, most important, help with fatloss during my cutting cycle but also to help keep my face clear as well. i am taking it to the end (last 3 weeks) of my cutting cycle because at normal doses it last 3 weeks and i have read in the past that it is best to take it (at any given point in a cycle) at the end because your thyroid would be at it's weakest. Thus, giving you better results. I can't say that this is fact, but it sounds like it would be correct and has good reasoning so im going to give it a shot.
