So far I've only done glutes and would like to start experimenting with other sites as my future cycles will include TP and Fina.

All I have now are 22g1" pins. Is this too large of a gauge to comfortably hit the quads? Would it be worth my while to get some 25g1"?

That 22 looks mighty thick sittin' next to my quad.

Haven't found the nerve to put it in a quad yet.
