Interesting you say that. Well I was on RU for approximately 3 weeks, and like I said found it was working great. Far less shedding in the shower and when I ran my hands through my hair. Had no side effects at all either and was using the 5% premixed solution from Anagen applying roughly 1.5 ml a day. About a week before I stopped however I did add in minoxidil and began to get chest pains, light headed, weirdly low blood pressure (although mine is normally quite low) 103/61 and a rapid heart rate. So yes it could entirely have been the minoxidil that did set off this episode and likely is. However just to be on the safe side I'd like to get some tests done before I continue the RU just to rule out the possibility that it could be causing cumulative heart damage. Waiting for my doctor to get back from vacation at the moment. I also workout 4-6 times a week and was having difficulty completing my workouts leading up to my full heart spaz. Right now it's been just over one week off both and although my heart rate and pressure seem back to normal,I still have a small amount of chest pain and notice I get out of breath still a bit easier than before.
