Finally got to use this for the first time yesterday for my full body workout. I am a bit behind since my wife just had surgery, so I have been out of the game for a couple weeks, but trying to get things back in order now. This is the first agmatine product I have used and NLA has made me a believer for sure, and also will be checking out their other products since this one does everything it claims. This product gave me the best pump I have ever had especially for the full body workout which is a pretty small volume per each muscle group workout. I noticed the pumps mostly in my calves, chest, and arms as these were all almost painful pumps, but enjoyable none the less lol.
