need some help with supplements. I have tried many over the years and have yet to find one that produces a noticable improvement. I ride about 100-120 miles per week with most being the normal club race. I also typically carb load the day before and still have the power bar and carb drink the day of. during the hard rides, especially the hills, my legs just get the burn quicker than what my fitness level and amount of riding should allow. Also on the hard flat pulls in the 26-28 range I just cant keep it going for long before my legs crap out. is there a supplement that someone can recommend that help with performance or trick my body in to thinking it doesnt hurt as badly as it really does.
