I've only done biceps but here's how I do it. Flex your bicep and mark when the peak would be. You will notice that it's higher up on your arm then you though it would be. That's where you want to inject. I use a 25G 1" needle and hardly feel any pain at all. I inject 3x a week making sure not to inject too close to arm day or back day at the gym...
