The OP at his lowest point has his FT at 18.7 pg/mL at trough which means his FT levels are higher at peak, no way are his problems FT related at these levels, in fact these levels are good for a 35 year old. The OP has seen a return of old symptoms even though his FT is way higher than pre-TRT, he should feel better than pre-TRT, he didn’t say I still feel better than pre-TRT, but feel like there’s room for improvement.
I say either his levels are higher than they were at 6 weeks or there is something else going on. He is going to have to check other hormones which TRT can influence, like cortisol, thyroid or other biomarkers. It could be as simple as iron deficiency or other biomarkers that are deficient.
His symptoms don’t match up with these numbers, he shouldn’t be feeling like this with these numbers. Mark Gordon has explained the reason why some men only feel good for a short while on protocol changes, this is one example below.
You’ve burnt out this 5-alpha reductase enzyme which allows for the conversion of progesterone and allopregnanolone and therefore you would experience symptoms, allopregnanolone stimulates Gaba in the brain.
He also stated that some men are losing up to 35 other hormones do to shutting down LH. A lot of doctors don’t have the proper training and education to work the problem.
