Is this Hot Ones 10-sauce pack? Because I'm a "pepper freak" and my wife got me that as a gift.
For my fellow pepper freaks:
The hottest one in that box is this:

I can get through a bottle of that in a week. Not nearly as impressive as I'd hoped, but somewhat hotter than Da Bomb: Beyond Insanity (also in the pack I refer to). Hotter sauces:
Da Bomb: Ground Zero. Pepper extract sauce. (I'd say this is easily a good 5x the heat of Da Bomb: Beyond Insanity, which is also in the "Hot Ones" 10-pack). The taste is smokey/chemically...but you really don't need much.
Da Bomb: The Final Answer Straight pepper extract oil. (~10x the heat of Da Bomb: Beyond Insanity). The taste is ...well, I'll have to remind myself later tonight. A more exaggerated version.
Magic Plant: Carolina Reaper Mash Paste. Technically, you're supposed to make sauces with it. I use it straight. This has
just enough vinegar to keep it from rotting in the fridge. It really is just mashed up condensed Carolina Reaper pepper. (~15x the heat of Da Bomb: Beyond Insanity)
But a real pepper freak should also immerse themselves in straight powdered hot pepper. (Generally hotter than flakes, since more of it spreads across your tongue. Flakes save more for the digestive tract unless you carefully chew them up).
Favorites:
Wicked Tickle: Devil's Chili Powder (ground smoked Bhut Jolokia aka Ghost Pepper. This is the most flavorful ghost pepper powder I've found. Really wonderfully smokey and fruity. And hot).
Sonoran Spice Company: Brain Strain Powder. (The pepper is "7 pot brain strain", hotter than ghost pepper but not as hot as reaper).
Wicked Reaper (same brand, I think): Carolina Reaper powder
Note: Sonoran Spice Company also has reaper and any other number of pepper powders/flakes. I like to keep the above powders and a 1KG container of habenero flakes on one of my file cabinets near my desk. I also have Carolina Reaper flakes, but like I said...if you're not chewing pedantically, you're not going to get all the heat out of the flakes. Your stomach and intestines will.
Overall, my favorite in general is the ghost pepper powder I cited. I like "The Last Dab" and the other hotter ones for things like chicken wings, chicken tenders, etc.
I have yet to find straight Pepper X powder, or paste. Apparently the breeder refuses to sell seeds. You pretty much only find it in sauces, which always disappoints me because straight powdered pepper is hotter on a gram for gram basis.
Plus, sauces always have some degree of vinegar, and that's appropriate for a narrower ranges of food.
It'll last. Put the unopened ones in a cool, dark, and dry place, preferably with steady temperature. Opened ones should last in a fridge for years and years, since sauces just about always have enough vinegar to guarantee that when combined with fridge temps. At worst, you get crust around the opening, which can be scraped out easily enough.
