Haven't done it in 3.5 yrs but last time I ran it 600mg/wk with 800mg/wk of test. It made my dick non functional. I vilified it as the Dr. Evil of ASS, it had stolen my mojo.
I retrospect I'm inclined to believe that now other circumstances in my life may have had more to do with it than the deca. I am going to give it a go again but no more than 3-400/wk.
