I'm in my second cycle and have been injecting my glutes, I've decided I want to try a different injection site, I also heard that it helps build the muscle more aswell, so I'm going for the delts, I'm taking 500 test and 400 deca a week split into 2 injections over the week. Is it best to split them so I'm injecting both delts at the same time also someone told me its best to inject once a week if in my delts because it gives u a bit of a dead arm for a couple of days. What is the correct pin length aswell with it being a smaller muscle .Cheers
