This is gonna sound weird but here goes I had a defective vein on one of my testicles which capped my endogenous testosterone at around 275. While waiting for surgery to fix it I went on exogenous testosterone (Androgel) for about a year. I found my libido, energy, cognition, etc. started to go through the roof so I only took enough to keep me around 500 and felt pretty good at that level as far as things just mentioned.
Had surgery and stopped all exogenous testosterone and after about two weeks with no other drugs testosterone is at 700. Free testosterone is 128. LH is 6. Estradiol is 26. No other labs were taken. Now here's the weird part. I actually felt way better on external testosterone at only around 500. Better libido, energy, cognition. Is there some weird phenomena that occurs with exogenous vs. endogenous testosterone?
I thought the labs might have been botched up so had another test and all results are pretty close to the first test.
