I have never had to rotate many injection sites before...I've always used long esters. Anyway, my current cycle has forced me to use as many sites as possiable. The problem is that I have a half sleeve that I paid over $3000 for...it was done by a very well know artist. I'm leery about sticking that delt...I don't want to scar my ink or have any other problems that may occur. Anyone have experience with this?
