A newbie doing e.o.d injections doesnt go down to well.. and pain of prop is horrible for first timer. I understand wat your saying bout him only having maximising results for 3 weeks..
But from experience my first cycle i ran sust deca for 8 weeks.. i got some great gains like 16lbs.. Im assuming all he has off is 12 weeks till season starts prob not even with pre season training..
As for recovery after it research a proper PCT..
