I went up to 140mcg and I have to say I love that stimulated clen feeling. Tremmers were slight but my heart really raced. My resting HR before bed was 80. The cross trainers I used don't have hr monitors but I can imagine that it was very high.

At the end of my two week cycle I experienced an uncomfortable tightness in my chest that went on for hours. And during cardio today, I had these sudden sharp pains in my heart. I'm thinking, can the clen and stick with the T3.
