Guys I am 64 now and been on trt for about 4 years(defy medical)..I will preface by saying I never did a cycle in my life before trt..I mention this because what intrigued me to try trt was I had pretty bad fatigue over the years and tried many supplements and all kinds of macro adjustments and it still persisted. I never had any sexual issues or classic low t symptoms but lab work initially show my total t at about 550...not low for sure but I wanted to see if being in upper limit would make a difference.. at 180 mg cypionate got me to about 950...honestly it didnt make me feel much better on a day to day basis..they cut me down to 140 a week and I stay around 600..not much difference from my start point..I can always take more t on my own if I decide so..my real question is I was making plenty of t on my own before starting and had no other issues but the fatigue am I now shut down forever and will require trt forever or if I decide to stop would I go back to my normal test levels? I have no problem staying on because doing so has been great motivator for gym and nutrition protocols..last year I did about 10 weeks of balkan oral primo but no other usage outside of trt...thanks for any input..I learned more on this board over the years than any where else( supplements, lab work,nutrition always years ahead of mainstream)
