Triceps biceps delts and pecs are good to go. I stick the pin from the bottom inside corner of the cleavage upwards at a 45 degree. Aim for the meat. 25ga 5/8" pin. I have gone up to 2cc(no test prop above 1cc though) into all but pecs. Quads and glutes are murderous on me. have nottried the ventro glute yet.
but i was almost brought to tears by the pain
