All I can tell you is, I use e-about a half hour before I get on the bike and then e-Fuel while I am riding, with a generous amount of water. It simply works.
When I do not have the engery or am low on engery, this stuff gives me the engery I need to continue and finish. I feel great when I get through, much better than when I started.
My hat’s off to you guys, this really is the best gel and fuel I have used. I do not think that I need to look for any others, I have found a keeper.
