I have searched, read and searched again. I see peeps are using a 1/2 29g slin pin for IGF injections. Im sure I could hit IM in the delts and probably Bis & Tris, etc. but Im not sure it would get very deep. AAS IM should be deep in the muscle for absorbstion. So with IM IGF injections does it matter if it gets deep in the muscle? Is there such thing as using too big of a guage like 23g 1 1/2 for IM IGF injections? Or is it alright if it barely gets in being it CAN be shot sub-q? I see most everyone agrees that they get better results IM so I just want to make sure Ill be doing this correctly with the most effectiveness.
