If you like Revenge, you ought to give Cytomax a try. I have been using the product for more than a year and I really like the benefits. For those that are intested http://www.cytomax.com
I used to use Cytomax then I thought I'd try their 'new' stuff Revenge. I really like it. I can't say that it is better though. I don't think revenge doesn't disolve as good. Anyone else always have stuff at the bottom?
I do the whole 'System' which Revenge is one part of 4. It helps with endurance.
TwinSpar, try thr Endurox Excel caplets. Good stuff but it won't satisfy your thirst endurance factor goes way up after a couple of weeks. I went from riding my Mt. bike a max. of about 8-10 miles in the summer heat and hills to 20 miles in about a month! Cytomax drink is ggod stuff I like it more than any of the other drinks although I have not tried Revenge yet but plan to soon since I need to mail order some parts and gear.
I just tried Revenge for the first time today. The stuff worked great. It was extremely hot out and I had not been on the bike in almost 2 weeks. I rode much longer than normal without the ill effects of the dreaded arm pump. My only problem was that it was so hot out when I came in, I felt like I was gonna vomit. Overall though great product. My only recomendation would be to use a little more water in the mix than on the directions. This will get rid of the hairball effect in your throat.
