So this cycle is going to be pretty injection heavy (6 days a week) and I really want to switch up my standard glute, quad and delt pinning. Thinking about adding Bi's and calves since I have a lot of meat there... any special precautions? Tend to be more/less painful? I assume 1" is good enough? Please dont say pecs cause I tried that last year and for some reason it hurt like hell.
