I have to be honest and say I just can not stand the taste of this stuff. I tried mixing it with Hammer Gel to hide the taste but alas I could still taste it.
From what I have read the more concentrated the mix is the longer it will last in the heat. They have a blurb on the site about mixing it to a slightly liquid paste and carrying it in a gel flask. I think they recommend this way if you are taking it on long warm rides.
The most effective way to do it, is to do it.
