Regarding looks you are doing great, given your situation/past
It's a good thing you reached out and it's great to see the members here give such good advices and have such care for your well being.
Those T levels are very odd. With TT level of 14 ng/dl (500 pmol/l) and free T at 10 ng/dl (343 pmol/l) you basically have almost zero shbg. And almost zero aromatization to E (which would fit with the symptoms you described).Was the free T measured or calculated?
If that total T really is true (usually the dr.'s take at least 2 measurements in different occasions), then obviously your hpta is not working properly right now. But with the free T I'm also thinking only adding oestrogen could help a lot. I've never tested that high free T and I'm not on trt, but my TT is in range.
I think the best would be to try what the fellas here suggested with the hcg and then a SERM and work it out with your endo.
I think it's good that they're possibly offering at least Sustanon there. Here it's Nebido, test undecaonate and the injection frequency is 10 - 14 weeks.
I hope things go forward with your dr. quickly. Rather than jumping the gun on self administered test, I think taking dhea could increase your well being a lot. But get things rolling with the new dr. and theres no need to self medicate.
