Interesting thread, I've recently started TRT and was thinking about adding in some deca as my tendons and joints are not keeping up with my gains even though I'm not lifting as much as I used to, I think I remembered reading something a while back about a guy who stopped cruising on 100-200mg deca a week because of some kind of ventricle enlargement? As for the boner issues does anyone notice a difference between deca and NPP for this?
