I've eaten a few whole ones, this year I tried a Infinity, Yellow T.S., a red Brain Strain, and some others. I did deseed them as I wanted to keep the seeds. I think this cuts some of the heat, one of the main reasons I will or would eat one would see just how bad they are and if they could be used to burn a certain person that I can't stand being around. I have to put up with him twice a year for a week at times and if it wasn't for the peppers I would most likely choke the hell out of him at some point. It such a stress reliever watching him eat a super hot with me and then watching all the pain and discomfort he goes through just trying to show how much of a bad ass he is, I think its the only time he eats any hot peppers. He's the only person I do this to, of course I probably suffer more than he does, but have learned how to tolerate most of it now with some of them, least wise while he is looking at me, but the physical after effects like stomach pain, pounding heart and throat burn can really hurt at times and the fact that I'm not in the best of health has my doctor concerned, but I get a lot of pleasure watching him squirm and cry like a baby after eating one, its worth every bit of pain I might go through.
Most of the time I just use small amounts for cooking or turn them into hot sauces and powders, I enjoy them much better that way than raw.
