Test done, just standard blood test, Free and Total, LH and FSH and all the rest...this was 5yrs ago, I don't remember every last panel on there but all the other standard things like CBC and lipids and all that were on there.
Anyway, Once I started TRT, it had been 1.5yrs since I had touched any gear of any kind....without TRT my levels are tanked, with TRT I'm good. I should also note my thyroid is fine despite years of T3 use...IMO, the hype and fear surrounding T3 is blown way out of proportion, but that's another argument/discussion.
As far as how long...I took a blood test and had a doctors appt. That was it, didn't take long.
I'm secondary....most guys who have low testosterone due to steroid use are secondary, not primary.
