There is some truth to this, why some "need" higher doses to "resolve all symptoms", the mood elevation.
Higher-end therapeutic doses.....sure!
Comes down to achieving healthy FT levels which will have a positive effect on mood.
One can easily achieve a healthy/let alone high-end trough FT level using therapeutic doses of T 100-200 mg/week.
Even then the majority of men can easily achieve a healthy/high trough FT level by injecting 100-150mg T/week especially when split into more frequent injections.
Yes, some outliers may need the high-end dose (200mg T/week) but this is far from common!
AAS & metabolites increase brain Gamma-aminobutyric acid (GABA).
Chronic administration of high-dose AAS causes downregulation which can have a negative impact in the long run.
As I have stated numerous times on the forum running too high an FT level can be just as bad in many ways as having too low an FT level especially when it comes to libido/erectile function and mood.
One of the reasons why many may end up struggling in the long run.
Testosterone also has a tonic effect on the CNS and can easily make one feel amped up, some may become agitated/anxious or struggle with getting quality sleep.
I would tread lightly when you speak of needing higher doses.
Bad move getting caught up in that more T is better mentality.
Need to throw in any dysfunction of thyroid/adrenals before claiming higher doses are needed!
Again we are talking therapeutics doses (100-200mg T/week) here.
