They all say that...
I have yet to see some "Oh we will kill you" hot sauce that will live up.
Closest was a sauce I bought in New Orleans c. 1992... That was really warm. In some ways, painful. Forgot what it was called, but it was early days of Habanero and it was mind-numbing.
Most of today's "You can't handle this" are pablum.
Then again, I've been abusing my taste buds for 40 years. So... may not be a great test case. But here in New England, Mashed Potatoes with pepper on them are considered spicy. So I think I can judge rectum-reaming hot. And none of this shit is it.
