I don't see any calves being used. Not that they are the solution for the shot-shy. But for the bros who are listing their numerous site injections, I recommend giving the calves a go. Definitely more difficult and painful than delts, which are really almost as easy as quads, but I'll tell you what, I realize their is no logical reason why spot injections will increase muscle growth, but I could swear my calves show gains when I shoot tren at about 1-2cc a week in each. If you aren't bothered by injections and have some calve size to work with, give it a try. At the least the first time you try it, it will let you work up that nervous feeling you probably haven't had since your early days of injecting.
