Allergen Warning: This product was produced in a facility that also processes ingredients containing milk, egg, soybeans, shellfish, fish, tree nuts, and peanutsThe workout supplement industry is plagued by pseudoscience, ridiculous hype, misleading advertising and endorsements, underdosed products full of junk ingredients, and many other shenanigans. Companies try to dazzle you with ridiculous marketing claims, high-profile (and very expensive) endorsements, pseudo-scientific babble, fancy-sounding proprietary blends, and flashy packaging, and we’ve had enough of it. Legion had to take a unique stand. It had to do what nobody else seems to be willing to do. NO PROPRIETARY BLENDS. We are 100% transparent with what’s in our products, and in what dosages. Not only that, but we back each ingredient with scientific studies that you can review. When you buy a Legion product, you know exactly what you’re getting and why. NO MISLEADING USE OF SCIENCE. We rely only on scientific research that actually applies to our consumers, healthy adults that engage in regular exercise, and we are very careful to not exaggerate findings or make unfounded marketing claims. NO”LABEL FILLER” INGREDIENTS. We have a simple standard that we live by: every ingredient we use must be backed by published scientific literature that demonstrates clear performance benefits. NO UNDERDOSING. We only use ingredients that we can include at clinically effective dosages. That is, the exact dosages shown to be safe and effective in published scientific research. It makes our job harder, and we won’t make nearly as much profit per sale as the “big boys,” but we believe our products will represent a standard by which all others can be judged. And that matters most to us. NO ARTIFICIAL SWEETENERS OR FOOD DYES. While artificial sweeteners and food dyes may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health, and that more research is needed. We’ve chosen to stay on the safe side and use the natural sweeteners stevia and erythritol and leave out the food dyesAssess your individual tolerance by mixing 1 scoop with 10 to 12 ounces of water and consume 15 to 30 minutes before exercise. Mild tingling can be expected and is a normal response to beta-alanine, but if you experience any non-optimum effects, stop and consult your doctor. We recommend taking 1 scoop of PULSE 15 to 30 minutes prior to a moderate workout and 2 scoops before an intense workout, especially one that lasts longer than 45 minutes.Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition.
