Creatine/nitric oxide

Over the last couple of years, I have been struggling occasionally with an irregular heartbeat during cardio workouts. I would consider myself very fit. I ended up at a cardiologist who did a stress test and found nothing wrong. It's been very frustrating, since, most of the time there are no problems, but occasionally, I just can't go on, even if I'm not working too hard.

I'm thinking the cause may be the NO2 Explode I've been taking. I've stopped for about a week and, so far, no problems. Has anyone else had a similar problem?
 
Too Much Caffeine?

I had same problem with irregular heartbeats, and suspect that the problem in my case was too much caffeine. I also read some complaints about amount of caffeine in NO-explode.

Yeah man, I have heard similar things about NO Explode.

It brings you up and makes you really full of energy for a short while.....

And then after an hour or so you crash really hard, and you just feel like ****.

Kind of what you experienced right?
 
No, I felt great during workouts and got good pump; however, later when I did any type of cardio my heartrate was very erratic and I just couldn't work to my capacity. Later, in the evening, my heart rate would go way down - 40 BPM.

The frustrating thing was that it was never consistent. Sometimes no problems at all...
 
I actually have issues with an overly accelerated heart rate (>100 bpm while at rest) when I used to take hydroxycut. After those problems, I've limited any supplements to a simply multi-vitamin because what was cause that in me, was not healthy.
