How many shots can you give yourself in a certain area of your body before you can no longer inject in that general area due to scarring of the tissue? Say guys on TRT have a weekly shot and he swaps quads every other week that would be 26 shots per quad per year. Now add to that the blast shots when blasting maybe 3 times a year. At that rate does it matter does the scarring eventually go away? I'm curious for those of us who like a certain area to inject in like the quads, if the body reaches a point of no return with needle scarring to make the area no longer usable. Or is there little scarring and it won't cause a problem.
