BSN Nitrix 360 Tabs Benefits Increases muscle endurance Helps with increasing blood supply to muscles Great for muscle definition Heightens the mind-muscle connection Predator Nutrition BSN Nitrix 360 Tabs Review Nitrix is the first supplement which was ever released for the purpose of increasing vascularity & helping bodybuilders get a pump more easily. Even before BSN released NO-Xplode, Nitrix was already on the market. After a decade since it was released, Nitrix is still a popular choice for those who prefer tablets for increasing blood circulation to the muscles as well as those who may just want a pumped appearance for cosmetic reasons. The combination of ingredients in Nitrix increase circulations of the compound Nitric Oxide which is what is responsible for your veins popping out when you train hard. For anyone seeking to maximise concentrations of nitric oxide, Nitrix remains a good choice.
