My nephew is on his 2nd cycle, 1st Injection cycle. If I pin his Delts no problem, Glutes or quads he claims he's Crippled I bust his Balls and call him a sissy cuz he has a bad temper, tell him its virgin muscles ,keep pinning it will go away, but he says its way above any normal pain. Does he have a low pain tolerance or could there be more to it. I cant relate , i can pin anywhere and feel nothing.
