Biggles you can get them already made up but the price of them is crazy compared to making them up yourself. I got 1,000 empty gel cap for around £15 Australian dollars. The cayenne pepper is peanuts to buy, the cinnamon isn't much either a dollar or so. If you compare this to the ready made up ones you'll find you'll save an arm and a leg.
Look up in Google 'cayenne pepper capsules' and be prepared to drop your jaws on the floor.
then compare notes.
Making them yourself keeps you quiet and off the streets...
