I did that. It's basically caffeine, antioxidants, and a few vitamins.
My problem is that when I come back, the last thing I want is caffeine. First thing in the morning I have a fruit shake and a multivitamin. No need for it then. I don't usually want anything just before I ride. So I tried it, but it justs sits in the frig. YMMV.
You can use that stuff before and during the rides. Probably wouldn't be any different than having a cup of coffee before the ride. After the ride, for recovery, you actually want something with the opposite effect.
Not really. Shipping is $6 and you get a huge bottle.
I received mine today by ups.
I tried it and went out for a ride, can't say I feel a difference. Even though, I did start out really well and managed high speeds at ease. Before my hands froze off of course.
But that could just mean I was revitalized after a 2 day break and I was well hydrated.
