does this help in ed ?

Best Answer:  I don't understand the question

How will this product increase my Nitric Oxide production? Is this product a better choice than L-Arginine? Are there any better choices to increase my Nitric Oxide production?

Best Answer:  Citrulline is the precursor to Arginine, so yes it is much better for N.O. production than Arginine. You can comblne both if you want for added effect but if you only want one supplement then L-Citrulline is the better of the two.

most data say to take 3 gram per day.  this product says 2 capsules per day.  To get 3 grams?  take 3 capsules?

Best Answer:  I mostly take 2 1 hr before activity.
