Ok I may be wrong here but I think I know why there is some inconsistency in the taste of cycle support peanut butter flavored. I noticed the other day that the cycle support tasted like **** again and I wondered why when the day before it tasted just fine (I mix it with two servings of mocha mudslide, it actually taste really good). It finally dawned on my dumb ass that it might be because I drank it immediately and that everything was not fully dissolved. (I was in a hurry). So I did a little experiment, I have been letting the shakes sit for ten minutes in the fridge or better. Then I did the next set by mixing and drinking immediately. The result was fairly conclusive, the shakes that were allowed to sit awhile were downright good while the shakes that didn’t were not as good and a couple of them were actually pretty bad.
Just thought I would share this in case anyone was still having the problem. Please note that to mix the shakes I am using a little hand held rechargeable mixer (Black and Decker gizmo) with a wire whip attachment. Not as good as a blender of course but still more then good enough for this. .
