It works for me instead of V with no side effects when I take about 2 grams and hour or two before. Also healthy for my circulatory system as an additional benefit.

Consider adding L-Citrulline please
from Sedona, AZ
About Me First Time User, Health Conscious
Without L-Citrulline to help the L-Arginine recycle 24-36 hrs, the L-Arginine alone only improves NItric Oxixe production about 30-120 minutes. Until the other key amino acid is part of the formula, I will have to switch to another manufacturer. (Reference Nobel prize winner Dr. Louis Ignarro's research)

Very good and WORKS!!!
from New York
This is overall a good product, it bothers me that it is 700 MG, it used to be 800MG, It is best to take about 3-5 G a day, which means you can be swallowing 7 caps a day.
