as far as not using 1.5" in my delt, i completely agree, but in your quad? cmon man, if you're afraid to push a 1.5" pin into your quad, you need to work those legs a bit more in the gym bro! hey, the deeper into the muscle tissue you get, the better.
regardless, all you need are 1.5" needles. when going on quads if you don't want to go as deep, just go part of the way in. no need to get all kinds of different needles for different injection sites IMO.
