The BA content to high in your gear. Muscle is having a reaction to much BA . 1 inch is deep enough unless your bf is that high. So I am assuming it isn't if you are running tren/mast since bf needs to be low for visual effects of tren (grainy look) mast (hardness vascularity) or you just get strength from them. Pin your side delt with 1.5 ml and other delt with 1.5 ml since u are using 3ml. If it still swells then it has nothing to do with how deep it goes . If u want to know the science behind why what I am telling is the truth p.m. Me it's to much to out in hear. Trust me it's BA content from a shitty underground lab that does not know how to make proper gear.
