Product review (5 stars): Still the best stuff!
I originally came across this stuff a couple decades ago when I was preparing to hike into the Grand Canyon, back then it went under the name "Gookinaid ERG". The stuff kept me alive & well hydrated throughout my trek, and I'm happy to say it still the "best thing since sliced bread" when it comes to long summer days working outside.  No artificial colors or flavors, less sugar and more potassium than other more heavily advertised sport drinks.
