Hello. I'm new to the extreme hot sauces, and i bought a couple of bottles for laughs amongst my friends and me. I just recieved Black Mamba & Mongoose. Supposedly Black Mamba is rated at 2,000,000-2,500,000 scoville and Mongoose 2,500,000-3,000,000 scoville. After trying both, the Mamba seems to be hotter than Mongoose, (even though mongoose is supposed to be rated higher), but Mongoose seems to stay hotter in my mouth for longer periods of time. Interestingly, my 'Possible Side Effects' hot sauce rated at a mere 283,000 scovilles seems to be hotter than both Mamba & Mongoose. Does this seem accurate? I only sampled a drop of each sauce. Are these results consistent or should I do more quantity wise(I dont want to get sick). Also, I'm thinking of purchasing the source, is that much hotter than the 3 brands I have or would it be a waste of money?
