GD, his free test is sitting at .087%. As we both know, given the chance to optimize our hormones, 2% to 3% would be the best range; maybe right in the middle at 2.5% would be ideal. If the OP were at 300ng on the serum with a 2.2% free test, without doubt, I think we would all tell him to seek treatment to increase his test. In this case, the OP is basically in the same boat as a guy with a 300ng/nl at 2.2%, literally same scenario when looking at the net result. However he is fortunate that his serum is already optimal (maybe even better than optimal).
I totally agree on the fact that he doesn't need testosterone treatment, as he has plenty of serum in the well. IMO, what he needs is the ability to draw more of that serum out of the well for bio available use. At 6.71ng/dl of free test, that is what I would kind of expect to see with someone in their late 50's, but I don't know if I would call it excellent. His SHBG is at 80. If he can get that down even into the 30's, he should be able to get his free test in the mid teens, which would better than double his free test, and IMO this would take him into a whole different place. Just my .02 on the matter.
And to reiterate again, I totally agree that the treatment of test is unnecessary. Any doc (again IMO) that would prescribe test to someone who has those LH levels and with that serum level is just looking to get that quick $buck$!
If the doctor would just focus on lowering his SHBG, which is probably halfway related to Vit D, then he would have a patient that is capable of producing the levels that we're seeing on TRT, but completely from his own natty. Not too many people over 50 can tout that!
OP, BTW, 1,000iu of vitamin D per day will not be enough for a therapeutic dosage. Most are closer to 5,000iu. Talk to your doctor about Drisdol, which is 50,000iu per week. You can even take it for a few months to get your levels optimal, then go to a OTC product with daily dosages.
