So I have been doing Deca and am on my second cycle. I am also taking Testosterone Enatathe. I started doing HGH but stopped because I felt like it was messing me up. Has anyone Done HGH while doing Deca? Is it healthy to do that? I stopped because I felt like my heart was racing just too much. I think that I am going to wait to do the Growth until I cycle down from the Deca. Does anyone have any advice for me?
