got a small injection question for ya bros. i only weigh 190, so im not as thick as most of u on this board. but im a d-1 track runner so im really lean. my question is, do i have to go all the way in with a 1 inch needle in my delts, like i said im not built like a bodybuilder, and when i put it all the way in it fells like im almost going in too far. they usually feel better if i only put them in 3/4 of an inch in stead of the full 1 inch.
