So when i start my cycle, What size needles will I need?

[hulkangryhulksmash]

I just figured calve looked easiest because the muscle is like right there. I am scared if I try it in my ass that I will miss the muscle. And my stats don't matter right now lol, I am not going to juice for probably 6 more months. My bf is like 21% So yea... I need to work before I juice.

I don't believe that you need to hit the muscle. The body will absorb it no matter what.
