Have you considered making your own? I have a good recipe for a habenero sauce and its pretty easy to make a ton of it. Ingredients can be obtained for $10 or less to make like a gallon of it

CHILI OILLLLLLL

Monoloco has a very hot sauce that's made without extract. It's only peppers, lemon, and garlic, so it adds not much else in terms of flavor. Otherwise theres YellowBird, which is very tasty and widely avaliable. Also check out https://heatonist.com/, they have a huge variety.

A couple of drops of Dave's Insanity Sauce with salsa is always my go-to.

Edit: Not sure if there are extracts in there.

idk but I went to a burger place last night and they had these little peppers at the sauce bar, I thought they were like pepperoncinis or maybe a sweet pepper of some sort and I munched one whole.

It was not. It was one of the hottest things I have ever eaten and I was sweating my friend was like "are you okay dude?"

The Hot Ones last dab is mustardy and really good imo

Matouk's Trinidad Scorpion Pepper Sauce.

I'm a huge fan of scotch bonnet pepper sauces and I think they'd fit your requirements well. Specifically, Lottie's Traditional Barbados Recipe Hot Pepper Sauce. Should be pretty easy to find online

https://www.2angrycats.com/products/hero-sauce 2 angry cats Hero Sauce a really tasty, really hot sauce. has a rich, dark, almost smoky heat, but not smoky like charcoal. just great heat from red peppers. I add it to soups, tacos, eggs, etc

I like that thai sambal stuff. It's about half oil, half chili paste. It somehow remains savory despite causing me instant sweats and ruining a few hours of my following morning.

Torchbearer garlic reaper is fantastic, the garlic flavor is really strong but you know exactly how that's gonna affect the dish so it's easy to use

I can also recommend just buying a bunch of habaneros/bonnets/reapers, throwing them in a blender with a little salt, and letting it sit on a shelf for a week until it smells like good pickles

I like Melinda's naga jolokia sauce. It's pretty cheap with a slow burn.

I'm a big fan of bravado hot sauces.

I think their spiciest flavors are the Aka Miso Ghost Pepper, the Black Garlic Carolina Reaper, the Garlic & Arbol Moruga Scorpion, and the Ancho Masala Scorpion Reaper.

For something a step down I like their Ghost pepper & Blueberry as well as their Serrano & Basil.

Their bottles are about $12-$13 for 5oz. I wouldn't pay more than that tbh.

Melinda's

I really really like Secret Aardvark but that's only like 5/10 hot
