Prior to just this last week, and for the last 14 months I have been injecting IM. However upon advice from my very well trusted source I have been experminting with direct injection. I pinch up the skin at the upper inside corner of my patella and shoot in at the base of the pinched up mass. When using this method I only use 1/4 cc. So far I am very happy doing it this way. (I use a slin pin but put the needle it till I feel it bounce off my patella. You will know when you hit it, it kinda wakes you up.)
