I bought Snake Water after my positive experience with KE4, another Ketoneaid product. I've tried products that include nootropics from other brands that are designed as pre- or intra-workout supplements, and some of them have worked, but Snake Water works better for me. It's easy to consume: Sometimes I drink a serving size (about a quarter bottle) undiluted if I'm in the middle of multiple hours of jiu jitsu, or if I'm doing sprints, and sometimes I'll dilute that serving into a bigger bottle of water with some electrolytes if I'm going to spend a long time on the stationary bike. I hate carrying around a bottle of pills, especially if I need to find water to drink them. I can just take a swig of Snake Water.I also feel more confident in keeping to a ketogenic diet using Snake Water as a pre- or intra-workout supplement and maintaining high performance. I don't have to worry about sugar or other stimulants that go into mainstream supplements, and I haven't had any problem maintaining high output during long bouts of intense exercise, like some of my teammates who are low carb and tend to crash have had.I've also heard that Tim Ferris uses Snake Water before his podcasts, which is a pretty good endorsement! I only have a couple Amazon reviews, and most of them are for Ketoneaid products because I *really* believe in them, and it's why I buy Snake Water and KE4 in bulk.
