Too much caffeine for me

Each scoop has the equivalent of two 8oz cups of coffee. I have high blood pressure so while I did have greater energy for weightlifting workouts I ended up with atrial fibrillation from the caffeine. I've switched to a non-caffeinated product and the atrial fibrillation cleared up. If you have any sort of health issues I'd consult with your doctor before taking any weightlifting supplement.
