Well, on my 4th day on clen, and still no body temp increase whatsoever. i'm always a little low, around 97F, but since the clen it hasn't gone up at all. i'm up to 60mcg at this point, and i'm definitely feeling the clen. do some people just not get the temperature increase with this stuff, or does it take more time? also, how much of a temp increase should i expect on this stuff? thanks.
