What does it mean if you felt good at the start of testosterone..or a lot better anyway...but then this goes back to the way you were?

I know high conversion to Estrogen can do this, but what about if E is only at 33?

I got my libido back at the start but now its gone. Does this mean that TRT will actually work for me, but i just need to find the right combo?

Im an ex finasteride user and I worry that TRT is not going to work!

(I was not on HCG at the start either, and now I am and still not right again)
