i did in high school. i had a ball given to me by a friend who wasnt taking the best care of him. his neck was pretty swollen and he was gurgling so i called my herp specialist and he brought over the shots. basically just inject under the scale between spine and rib, then massage into the muscle. pretty easy but hey im a licensed embalmer so im used to injecting into things lol. i would reccomend if you can getting the vet to do it for you, especially if your thinking of trying to do something like that with no help.
