I have, but its difficult. First, i set my vial on the hot plate of my coffee maker. You will have to leave it there for atleast 3-5 minutes. The vial should feel like hot water out of tap. This should make the oil thin enough to pull into slin pin. Its still gonna take 2 minutes to pull a half cc. Then, as long as your lean enough, a half inch long slin needle will reach your muscle if you pin in your delt. You will have to burry the needle the whole way.
You have to leave room to asperate so you can only do a half cc at a time. Its a lengthy process, but in a pinch it will work. Why do you want to do this, no 3cc pins?
