when i ran out of 25g 1 inchers, i started pinning 23 1.5s on my quad.
i left a little less than .5 out, and just kinda set up my other hand as a holster to prevent it from going in and out and shaking around.
you def feel it go in a bit more cause its thicker.
i got high a few times before id inject, and it was super scary to jab the 1.5er into ur thigh...talk about paranoia. my buddy kept trying to make me laugh too which was fucked up
