Hello,
I won't get ito the debate of whether it works or not, but MHO is that it doesn't hurt. I use Carbo Pro and many other products of SportQuest Direct
http://www.sportquestdirect.com/. I by accident one day, I started to pour their protien powder, Interphase vanilla flavor, into my water bottle that I had already added Cytomax Orange to instead of the Carbo Pro. Instead of pouring it all out I just added the Carbo Pro and SOB if it didn't taste like a creamsicle. I pretty much use this on all my efforts whether running or biking of more than 1.5 hours. It still tastes like a creamsicle even after it warms upand it gives me some protein along with my carbs.
An aside, they are not huge company and I have been witness to a conversation with more than one top triathlete that have sponsorshp agreements with conglomerates. They essentially thanked him for the product and still use it regularly even though they're collecting a check elsewhere.
I am a die hard Clif bar user nothing IMHO even comes close. But if you are a gel user look into Hammergel. They're flavors are great and they make a quart bottle. Best reason, no waste or trash. Fill your flask and recycle the bottle when done. To avoid gels altogther, Carbo Pro in your water bottle. Check the website for mas 411.

disclaimer: I am not an elite athlete by anyones standards, especially my daughters. I was forunate enough to win a years worth of product from our tri- club. Prior to that I WAS PURCHASING and using the product and when my year ends, you will still find it in my pantry.
