EFS-Pro can be mixed differently according to your needs, from 80 calories and 933mg electrolytes to 160 calories and 1,866mg of electrolytes.
Even at its most potent, EFS-Pro has never given us a hint of gut rot. Best, EFS-Pro has not been designed to taste like fruit punch or lemonade, it drinks like flavored water, with only a hint of lemon and almost no sweetness, just right for a long hot day in the saddle.
