1 inch needle works great.... I have done up to 3cc's in the shoulder, but if you are gonna shoot this much, make sure you rub the shit out of your shoulder after you shoot it..... I had an abcess once in my delt from some Bunk Test years ago.... My entire arm got this rash growing down it, and felt very hot to the touch.... Had to go to the ER, and some IV anti-biotics, then I was fine..... However, many shoot up to 3cc's in the delt with no prob... Rubbing vigoursly is always reccomended post shooting to spread the oil out a bit, for better absorbtion.....
