The [http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=gu+energy+gel+peanut+butter&rh=i%3Aaps%2Ck%3Agu+energy+gel+peanut+butter peanut butter flavored Gu] is different enough to justify its own entry. The peanut butter flavor is far less sweet than the regular Gu flavors, but if you like peanut butter it can be a lot more palatable. It also substitutes a little bit of fat and [[Protein]] for the carbohydrate, as well as having a tiny bit more sodium and [[Potassium]]. I find this flavor digests particularly well and I'd recommend trying get if you're a fan of peanut butter. Obviously, if you hate peanut butter or you have a peanut allergy this is not going to work for you. The Peanut Butter flavor is one of the thickest gels, and is quite a bit thicker than the other flavors of Gu. Even in warm conditions it tends to be a little too thick, and in cold conditions it can become bit like a chewy candy such as taffy, toffee, etc.

Vi Endurance= Vi Endurance has no [[Fructose]], so it's ideal for those that suffer from [http://en.wikipedia.org/wiki/Fructose_malabsorption fructose malabsorption]. It has a little fat in the form of [[MCT| Medium Chain Triglycerides (MCT)]], as well as some Taurine, which I think are good things, but probably the amount is not significant enough to make much of a difference. Note that MCT can cause serious digestive problems, but probably not at these levels. There is a little [[Caffeine]], intended to increase the carbohydrate absorption rather than to improve performance. I found the Vi Endurance very easy on the stomach and a worthy alternative to Hammer Gel , though it's only from the manufacturer and so it a little more pricy ( $1.64 with shipping.)
