You could crack open a AA battery and pour the acid inside it on whatever you're eating. It'd certainly be cheaper, and it might taste better and be less poisonous too!
Seriously though, it's on Amazon right here.
I have a very high tolerance to spicy food. The bottle says 137,000 scoville but that has to be a mistake cause this sauce had me writhing in pain. It was so hot I felt like I was gonna throw up a few times and it will melt your insides as it makes its way through your body. It comes in waves so you think it has passed and then you get hit with another wave of pain and misery. So in other words this hot sauce is really good and I would highly recommend it. (might be tolerable at lower amounts but when I add hot sauce I just dump a bunch)
