Grenade .50 Calibre is a hard hitting, pre workout detonator designed to make every workout an explosive, energy fuelled assault.Powered by Grenade, the multi award winning sports nutrition specialists, .50 Calibre combines full potency dosages of research-validated ingredients so as to deliver devastating energy levels and incredible pumps! .50 Calibre also contains MDS (Muscle Defence System) anti-catabolic support designed to help avoid excess muscle breakdown.Containing over 20 University tested ingredients, in high-potency dosages, 50 Calibre was formulated by our expert R & D team after evaluating and considering every possible natural component that has been studied to enhance physical performance.Grenade .50 Calibre contains large dosages of Citrulline Malate (the most proven NO-boosting amino acid), high nitrate Beta Vulgaris, high-dose, flavanol-rich Theobroma Cocao and numerous other effective ingredients that support muscular blood flow. Of course, no pre-workout product would be complete without beta alanine, caffeine and creatine, as they are backed by thousands of scientific studies in exercise performance. Additionally, bicarbonate electrolytes are added to resist the energy-sapping effects of lactic acid (lactate) and BCAAs are added for anti-catabolic support.Another advantage of .50 Calibre is what it doesnt contain. Grenade researchers have studied DMAA from Geranium closely and have decided not to add it to .50 Calibre. Research indicates that DMAA combined with caffeine has a vasoconstricting effect (it narrows blood vessels) this defeats the main purpose of a nitric oxide productthe whole point of nitric oxide (NO) is that it widens blood vessels so that more blood, energy and nutrients can be delivered to the muscle for better performance and a better pump. Also, studies have so far failed to detect improvements in performance from taking DMAA but have demonstrated increased blood pressure.So the ingredients in .50 Calibre, along with other botanicals and essential micronutrients combine to constitute what we believe is the most innovative and effective pre workout, nitric oxide product available on the market today 50 Calibre, the ultimate pre workout ammunition for better exercise performance.Suitable for Vegetarians.
