Never tried it.
Why? Because the initial
reviews indicated that to get the desired effect that the percentage of Qhit was equal to, or above, the amount of flavoring I was already using.
There were rumors that it was going to be reformulated to make it stronger, but I have not read anything that indicates it has been.
I have heard
reviews that capsasian (sic?) extract was used to good effect at low percentages. Haven't tried it yet. (The dog I am watching for a deployed soldier loves the stuff and it gives him terrible gas and other digestion issues, and he could knock over my supplies if he had a mind to. It's tough enough having anything with peppers in it with him around as it is.). The most consistant good
reviews for that extract have been the one that TW sells. Forget their name for it. Diablo? Maybe?
So, now you know what an observer thinks he knows. Maybe an actual user of the stuff can chime in here?
