This is low SHBG.
Without SHBG for T to attach to, it is quickly cleared from the body.
Pharmaceutical drugs, of all kinds, and a significant percentage of them, increase SHBG to some extent. Some just a fraction of an amount, some can really boost it up.
This is a big problem with the birth control pill that many women take. Ramps up SHBG.
I have seen some literature that many pain killers, NSAID’s, and such increase SHBG, probably to a much smaller percentage.
I do not know the main characteristics of why this is so. I would speculate that it has something to do with the liver, in that anything that taxes the liver, such as many pharmaceutical drugs do (and remember, most do at a safe and reasonable amount) can raise SHBG.
SHBG is produced mainly in the liver. How this can potentially react when other drugs is up for much speculation, and I don’t think anyone can answer that with any specificity.
It is like how many drugs are also pro estrogenic. We have theories and ideas and concrete reasons why many do, but others we do not.
Many older men with liver disease often always have high SHBG.

The body is always looking for homeostasis, and to protect itself at all costs. It will send a message to the liver to stop producing SHBG when it is poisoned by excessive T.
Your body has nothing for the T to attach itself too, it will just simply dump dump dump and by mid afternoon, you will have no T.
I think many men on TRT end up with lower SHBG because they take to much T.
Why? Because they think that T will solve all their energy and QOL problems, and that once they start TRT everything will be gravy.
When they don;t get the energy and overall experience from 100mg or equivalent of T in a gel a week, they increase dose looking for more energy.
There is no SHBG in the world that cannot be stopped by a huge overload of testosterone.
The problem is what to do once it goes down low.
So we need to be careful when administering T
The increasing SHBG we see as gents get older is the bodies way of trying desperately to hold onto what shrinking amounts of T it has every year.
I.E., T bound by SHBG is more usable than previously thought.
SHBG goes up as a result of the bodies decreasing ability to make T every year.
SHBG goes up because your T level goes down every year past the age of 25 or so.
Raising SHBG is the bodies desperate, and fruitless way, of preserving T.
