Stats aren't really important here, but wanted others to voice on this concern.
When I shoot in my quads with a 25G 1' pin, I get about 7/8 of it in, and seem to keep hitting a wall where the pin doesn't want to go further. I usually just bite the bullet and force it through...
At first I thought this might be a nerve, but it's usually on every injection in the quad that i find this. I always move around my injections and only hit quads once/2weeks (rotate through delts, glutes, quads, calves, bi-ceps), so I don't think it's scar tissue.
Anyone else get this?
