Pekkerwood on here went through the whole cardiomyopathy thing and his heart is now sitting around where yours is. You should PM him and see what he has to say. Maybe he will see this thread.
My advice is that if youre not happy with how you feel at your current test levels then see an endo and maybe they will consider the TRT. I was sitting at a total test of around 70 or so and youre in the 300s so I can see why they hesitate. Hell, my doc made me wait almost 1 yr before she would put me on the test because she wanted to see if my test would come back on its own. I was honest and told her about my steroid use, and yeah sometimes it does come back. Im assuming yours had been in the 300s for years so yours is obviously not getting any higher. That is a normal range though for certain age groups.
I just want to feel alive again and I haven't in a while now. Just been trying to make it but it is getting to me more now. Like I have said in the past and I am being honest, I have not taken anything in more than 6 years now. It has been hard but I pushed my way through it.
I know you have been through a lot to and I appreciate your help on this.
Thanks
