Prepare you smoker with desired wood or charcoal. I use a combination of a hardwood charcoal with wood. I used Pecan wood this time.
Melt the butter and add the chicken stock. Add about 1/2 teaspoon granulated garlic. Allow to cool down, then inject the turkey a dozen or so times with the solution.
After injecting, rub the turkey all over with a little olive oil and season with salt, pepper and granulated garlic.
Cook at about 250-300 degrees until the internal temperature reaches 160. Remove from the heat and allow to rest for at least 30 minutes before slicing.
