Igf and the needles

[Motorcycleguy]

I have heard a few different answers for needle length and preferrence. I will be doing IGF r3 and injecting into the delts, the bis, and the tris. My question is, will a 1/2" 29 gauge needle work for these or will it need to be longer?

well, just managed to come across the answer.
