Dubious claims
I'm beginning to think that "gamer drinks" are pretty much a scam.  I've now tried three different brands and I haven't noticed a single difference in my playing after drinking them.  As for Glytch, the taste was fine.  Sweet, but not overly so.  It mixed easily into water.  No residue at the bottom of the glass.  It's fine, I guess.  But for $35 I'd say it's a hard pass.
