xbiker- it is much easier to do lat injections if you are standing facing a mirror, and put one arm up on the wall next to you or something... You don't have to go behind your body like you did... You can put it right underneath the outside of your armpit... it is much easier to do yourself that way.. if you have the luxury of somebody doing it for you, you can line your lats with shots if you see fit. and if you are using fina (or anything else good for localized growth), put half in one lat and half in the other... it looked like you only did one cc, so maybe just switch back and forth between lats, but on bigger injections split them up.
