- 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!
How it works 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. 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.
