I use 1" needles for all injection sites. Chest, Quads, Delts, Glutes, etc. I think the only way you'd have a problem is if your body fat is really, really high.
OK for pecs, tris, quads you can use a 1" pin but for glutes you should ALWAYS use a 1.5" pin and make sure it is inserted all the way. IM injections work best when the compund is injected DEEP into the muscle. Actually you will find that when you inject into the muscle and you don't go deep enough that the site will be more painful than with a correct (deep) injection.

are one inch pins handy as hell?fuck yes...........God's gift is highly debatable though,as an atheist I find that comment comical at best.
I agree with mrribbit about always using a 1.5inch for glute shots to get the injection deep enough into the muscle tissue.one inch being used for all other applications,otherwise.
