I buy it all the time from Walmart. I prefer the ones with the caffeine because it just has a little more flavor to it a little more zing but sometimes it doesn’t really matter. It’s like it gets stuck in my throat and it’s just hard it sits there for a minute like my throat that’s connected to the upper part of my chest, sometimes I get tired of that 20% that 15%,protein but our choices aren’t limited you can go to just drinking a regular protein shake with your own stuff in it. I have a problem with a lot of these flavored syrup. They just taste like water with sugar in it, even though it has no sugar in it , either way that’s what we’re living off of
