Yes:
“To answer your question, externally administered Testosterone will send a signal to the HPTA that Testosterone is present, subsequently reducing ones LH levels. (Lut. Hormone)....”SHBG (Sex H. binding globulin) will also be significantly reduced.”
Thanks for the more scientific version of part of what I said.
It should make for some caution with regard to supplemental T, UNLESS the natural T readings, before any supplementation, are far far below normal for someone’s age.
Absolutely, if you’re on TRT, it’s for life.
To add, the “ranges” of testosterone for certain ages are not sufficient at all. In fact, most endo’s are oblivious.
For instance, the range for a 20-29 year old male is 300-900.
Think about that. That’s insane. If a 20 year old has a T level of 350, they are far from normal. But, alas, that is the current consensus of the endocrinology community.
There is the slow shift that I’m seeing to treat symptomatically rather by the number, but it’s taking too long and I’m seeing too many men not living to their full potential.
