After a particularly intense arm workout last night I taped my arms for the first time in years. L was 19.5", R was 20". I'm sitting at 240lbs right now on a self prescribed TRT of 400mg test/200mg masteron. I spent years blasting huge doses, pushing my weight up to 280lbs, and lifting stupid heavy weight but never saw that 20" mark. Only thing that was really changed has been a strictly pump driven arm routine similar to what Surge Nubret used to do. I also took some tips from a brief stint working out with Bob Cicerello. Supersetting Tri's/Bi's with light weight and minimal rest with extreme pump being the goal. I also do them 2x a week after another major muscle group. Thought I'd share what worked for me.
