Just bought a really really hot hot sauce and got it for a bargain! It's called Mad dog pepper extract. 5 million scoville units. http://www.amazon.com/MAD-Pepper-Extract-Million-Scovile/dp/B00170SLO4
Also bought last week Blairs mega death hot sauce, great on burgers and has a good kick!
Feel free to share your hot sauces too!
