Those sauces were just some 'sensible' examples that we 'and the lads' had tried at work. The Mad Dog was more than enough for me and went past the silly stage of heat.
Take a look, the hottest one they do, limited edition of 999 (with a cost to match) AND a document you have to sign stating you know what this stuff is & how to use it has a maximum Scoville rating of 16,000,000. Yep, 16 MILLION.
