So yes, they worked well, but they were not natural and potentially dangerous, depending on who took the product. So knowing Muscle Nit what's in the supplement you buy is smart, safe and necessary!They want to be aware of what kind of so-called "natural" ingredients are used. There is a herb that I can tell you that you need to be careful with, especially if you have heart disease or high blood pressure. This herb is called Yohimbe or Yohimbine. It was quite popular at one time and used in some over the counter male enhancement products, but the side effects of this herb include runny nose, anxiety, red face, high blood pressure and fast heartbeat oh yea and a strong erection.
