I am 11 days into a 6 week clen/t3 cycle and I have also continued to take the phentermine I had already been taking for a month before I started. I am 36 and weigh 240 with 24% bf(before I started). I check my heart rate every few min when doing cardio and check blood pressure everyday. My heart rate is about the same as before, maybe a touch higher and bp has gone from a average of 115/68 to 130/79 at the highest. After the fourth day I started getting the shakes for a hour or so after taking the clen. I started at 60mcg clen 50 mcg t/3 and slowly worked up to 100/75, I am going to stay there till the shakes stop. So far my body temp has stayed normal. I will start keto on the 15th day. I will post results and pics when finished.
