Wow, just watched that video. Gotta say, 2x I used my quads, 2 x it was a horrible experience. I'm pretty sure I hit nerves both times. It got infected and became very sore. Limping around for at least a week.
Just recently, I had a dumb idea to use my calf for 1ml. Horrible idea
I was off work for 9 days. Infection was so bad i was on iv antibiotics.
Everyone's different, some guys like it
