Is there any issues besides scar tissue in regards to pinning the same muscle x2 a week. I'm on a sust 250 cycle, and I pin 1 amp EOD and I alternate only between my left and right quad. So the same quad is getting pinned once about every 4 days. Would this hinder my gains in terms of the stuff not being absorbed as well because the same muscle is being pinned too often? or is this completely fine and has no impact on anything besides scar tissue?
