L-Arginine is a popular amino acid for its amazing nitrogen retention ability.* Nitrogen as you are all aware is one of the key elements in muscle protein synthesis. Some plants can absorb nitrogen, but we mammals have to make do with the stuff we make ourselves. Arginine is mostly present in protanines and histones, two proteins commonly associated with nucleic acids (like DNA and RNA).

I had used this in the past but had an awful time with the taste.In the past I tried mixing it with all sorts of things with no luck. This time I decided to try mixing it with a little grapefruit juice. It worked.Mixed with grapefruit juice you can barely notice the taste. I've only been back on it for a week but do like what I see so far.

Good product! But the flavour is horrible. You have to drink it with juice or just chug it with the nose plugged.

Quick the b****ing about the taste my fellow future bodybuilders/athletes. This is a RAW supplement that enhances N.O. in the body. It was never intended to satisfy your taste buds nor your psychological thought of what GOOD is. I love this product and will purchase another as soon as I am running low.
