Title: Effective with a likable flavor
Product review: I've used R4 for over 10 years. For me, it keeps the calf muscle cramps at bay and diminishes my post run fatigue after a 2 hour or so trail run. I'd recommend buying sample sizes of several flavors before purchasing a large container. The flavors are truly a matter of personal taste: I like the vanilla and fruit punch flavors and not the orange or chocolate. Also, some flavors agree with my stomach better as post race beverages (the vanilla), while others I can take in a sports bottle during the run (the fruit punch). The lemon lime in the Accelerade version also suits my stomach, as a chllled post race drink. All are better with cold water, in my opinion.On a side note, the vanilla mixed with a bit of powdered milk makes a good coffee creamer for backpacking. I'm not sure if the heat of the coffee kills the effectiveness of the R4 ingredients. Maybe Endurox will come out with a Coffee Latte flavor? :)
