Add the onions, garlic, chili powder, cumin, garlic pepper, oregano, paprika, cinnamon, salt, crushed tomatoes and tomato paste to the meat and cook another 5 minutes. Add the beer and stock, and stir to loosen any bits from the bottom of the pan. Reduce the heat and simmer for 10-15 minutes, until thickened. Season the chili with salt to your taste.
