Long term pinning in the biceps has definitely done some damage. My left one does not fire optimally and I do have some atrophy and scar tissue. Luckily my biceps have been big a long time so it's really only noticeable to me. But if I knew then what I know now, I would have been a lot less "excessive" with site injects.
Stick to delts, glutes and quads with the bigger pins and use slin pins for the smaller stuff. That's my advice.
The size increases people see from site injections is also just temporary and once the swelling is gone down it is gone. Many bodybuilders still swear that there is local growth caused by injections but it really is all systemic.
