Back at it today after a 4 day holiday break from lifting. But I was able to test the Surge Workout Fuel during a very, very active 4 day stretch of hiking, swimming, volleyball, a 5k and biking in continuous 100 degree heat. My family could not keep up. The daily Surge Workout Fuel kept me hydrated and energized, even though I was not conditioned to the heat coming into this weekend. Full disclaimer: I don’t drink alcohol, so did not have to fight the typical holiday late night drinking and hangovers. This product is legit (and I imagine it would be good for hangovers, as well)
