I just started ep clen today, within 30 min I experienced some shaking of the hands and an increased heart rate. I never tried clen before, so I guess I'll do a mini log. My first dose was 40mcg, I'll be running some ketotifen fumarate along with it, I'm gonna try to do a 6 week run with this....some of you may be interested due to the fact ep is really cheap on the wallet.....so far so good...
