If you don't have the time
to ride more, what do you want this product for? It won't suddenly free up a bunch of time for you ...... or if it does, I want to know more about it because I could use some free time!!
If you don't have the energy
to ride more than that, the best way to develop that energy is by gradually increasing your mileage while eating and drinking properly. Do 150 miles next week ... 155 the week after ... and so on.
My mileage varies from some weeks in the winter where I don't ride at all (rest weeks and weeks where I'm too busy to ride), all the way to weeks in the summer where I do 750-800 miles. I've been doing that for 6 years now, and I've never had to use a product to increase my endurance. My endurance has come simply from cycling lots and pushing myself beyond my preconceived notions of what I could accomplish ... combined with a bicycle that fits, equipment that works, and a relatively decent understanding of what my body needs in the way of nutrition.
