I was Dx with hypogonadism in the early 90's, total was 189, had gyno that needed surgical removal on the left side. Was put on TC, 200 mg/2 wk, the standard back then. Worsened the residual gyno, asked my doc to try Deca. Switched to that 200 mg/2wk and a low dose of HCG 350 IU 2x/wk. Ran that from 1995 until 2005 when HCT and iron was really getting high. Low dose in today's world but I was about 250 at 10% body fat, it worked very well. No issues with ED or anything else. Had we known more then, simple phlebos would have taken care of the HCT and Fe. Was put on Testim instead, that didn't do shit even at 2 tubes a day that was very expensive and still had elevated HCT over time. Ultimately went back to TC 100 mg 3-4 d, get regular phlebos along with 500 IU HCT 2x/wk. No issues at this time. Interestingly in my younger years I was more prone to elevated E than I am now. Have considered adding some deca for joints, at age 62 I'm a mess, but Deca used to blow me up a little along with BP, don't need those issues now and ED is more of a problem, even considered a little masteron E for libido with the T. Everyone is different, I grew like a weed on a low dose of Deca that others probably wouldn't even notice an effect.
