So I recently started a clen/t3 cycle after many months of research. I ramped the clen up, starting at 20mcg to assess my tolerance since this was my first time taking it. I got to 100mcg, and even though I had no shakes my resting heartrate was up and so was my temperature so I decided to keep it there as I had planned. So 3 days go by at 100 mcg and everything was fine. On the fourth day however I wake up in the morning with chest pains and I had trouble breathing deep. Basically I could'nt take any deep breaths without pain. This lasted the entire day, but it would come and go throughout the day. Needless to say I discontinued the clen and the next day I was much better, and basically completely fine after 36 hours.
I really don't know what went wrong. I have done ECA stacks before and I'd been fine, and even with the clen I monitored everything each day. I would check resting HR and blood pressure, temperature, etc. Nothing was out of the ordinary until this happened. Any of you have any ideas as to what happened? Would it be foolish to go back on clen but at a reduced dose of maybe 50-60 mcg?
