It stalk is fuzzy and under the leaves are fuzzy too and the pepper size is small
What kind of pepper is this?
Tiny pictures are hard to tell but from your description, sounds like a variant of a Goat's Weed Pepper. I'm growing Black Cobra this year and they're a fuzzy, very prolific pepper. Extremely tall as well. Mine are all over 4 ft. with tree-like growth. These peppers can be very hot. Tried one the other day and had to make my way back to the kitchen for a glass of milk :)
If it's Goat's Weed the peppers will start green, then turn dark purple/black, then red as they mature.
Yea I researched enough to find out that when they mature they turn purple more then red
