Yes, I finally found the good spot to shoot in my quads again. It's been over 3 years since I've hit quads because I was shooting 3cc in them back and forth, back and forth for 2-3months during a cycle years ago, and they got where I couldn't even bend my leg to put my pants or socks on for a few days after injection, so I just never hit them again after that. Every spot, or your delts, glutes, and quads at least, have a perfect spot to hit. I'm glad I found that spot on my quads, because I swear my quads must be the veiniest and nerviest of places. I used to hate quad shots, but nothing to it as long as you hit that g-spot. There's always a spot where you can't even feel the pin go in. It seems to be about the size of a nickel in each spot too; delts, glutes, etc...
Just wanted to share that. I'm glad about it.
