If you are properly stepping up your TRT dosage, titrating to effect, and you begin feeling high estrogen symptoms, wait a month. You will not grow breasts in that time. But if you still have these elevated estrogen symptoms after a month, add a small dose of anastrozole (dosing per protocol). IF the estrogen symptoms go away, the problem was the estrogen.
It would appear an alternative is just to take a very large dose of testosterone. You can not decrease current dose, because you have already been there, and it did not work. And letting things calm down for a month or so means you are now stabilized (just changing hormone levels, up or down, can cause side effects temporarily). It's looking to me that huge doses of testosterone may ablate the estrogen symptoms. They might be just running right over them.
The problem with the latter approach is no one knows what taking testosterone--or estrogen for that matter--to 2 or more times the top of normal range does to a person (man or woman) long term. There is not one shred of evidence-based medicine to support that strategy.
But we do know, for instance, greatly elevating DHT will cause the hair to fall out. Those applying T cream to their scrotum will necessarily greatly elevate DHT. I've seen this cause anxiety, high blood pressure, urinary voiding symptoms, and hair loss. Not everyone can afford a hair transplant.
I've seen scrotal application of high dose T cream take DHT to 800. That is more than 10 times the top of normal range! No one knows what that does long term. Sure, you may feel good now, but who knows what is going on in the background?
My position has been that it is far better to have added LOW DOSE anastrozole along the way, and maintained T, DHT, and E more near normal range. Then we are taking into account any Endocrine Disrupting Chemicals (EDC), Androgen Receptor Resistance, and the fact mens' T levels, on average, used to be higher (hence the lower "normal ranges").
Again, I do not ever want to prescribe any drug which is unnecessary. But I have also learned we generate health problems when we slam biological systems too far in any direction.
These are simple facts the Anti-AI Crowd cannot overcome.
