I like to lift so i have taken an assortment of pwo supplements. I dont think i would really like to take any of them before riding. I stay away from the ones that are heavy in stimulants. The can be really bad on your heart. Like Nivek said all the gotta do is put an * next to shit and they can pretty much say what they want. I know one of the pwo had what was called dmaa in it which has been linked to a couple deaths in the military. Not saying there werent other underlying issues. Just do your research and be very wary of what you put in your body. I like to eat fruit before i ride then the adrenaline and beers keep me going.
Caffeine is enough for me. I know its not great to feel you "need" but its part ritual at this point. During the work week I get away with a cup or two in the morning, not one of those all day coffee drinkers. And it has to be good coffee.. I prefer my own and make it with a french press and drink it black.
I really only drink water or seltzer (outside of beer/wine)... and have gotten much better about hydrating during the activities. Also have some new bars I like.. they are baked, wheat free, lots of fiber and decent amount of protein.
I completely forgot, I used to take these chews/drinks. I. Sure you guys might have heard of it, but the company is called FRS. They use natural antioxidants as a fuel source. So its basically healthy energy. Pretty good stuff and its heavily endorsed by a lot of huge popular athletes. Can be expensive, but I wait for the many awesome sales they have, like when they have a 50% off and free shipping promotion. They even have a free sampler package, you jusy pay shipping:
