Stacking this with Noxivol and Noxipro right now and this combination is awesome. Unstoppable energy, muscle pumps and endurance. Always been a fan of CTD Sports and the new Nitro product is an awesome additive for extra pumps. Stack it every day at the gym.
CTD Labs has made quite a few supplements that people like, but this NO Nitro is something that is not really backed by science. It contains only a few ingredients that will increase vascularity. When I buy a pump supplement I like to use ones that contain a lot of different ingredients shown to increase blood flow, so if one of them does not work for me another one will. With that being said, this will give you a benefit over taking no pump supplement at all.
