Cellucor G4 NO3 Chrome Brian E. December 12, 2014 Pump Supplements, Reviews Cellucor’s brand new G4 series is seeing an update to its pump product NO3 Chrome. One of the new ingredients featured in here is called Nitrosigine, a patented arginine derivative that combines arginine and silicon. This is one of the most popular compounds right now for increasing nitric oxide production, and delivers a pretty good pump in other products I’ve tried with it. I’m really excited to see what other changes Cellucor makes to NO3 Chrome, so be sure to check back soon for a complete review as soon as NO3 Chrome officially becomes available.
