The aptly named Instant Regret peanut butter is packed with capsaicin - the component that provides the heat within a chilli.
On the Scoville scale, which measures the heat of chilli peppers, the peanut butter boasts a whopping rating of 12,000,000.
To put this in perspective, the world's hottest chilli - the Moruga Scorpion - rates at 2,000,000, as does the most legal variant of pepper spray.
The spread is not for the faint-hearted and even comes with a warning to users. It is not suitable for the elderly nor children.
So fiercely hot is the butter that the retailers, Firebox, had to persuade the factory to produce it.
