Your question has already been answered years ago in the 2014 Di Loreto study on PFS patients.
These were the findings:
Percentage of epithelial cells (basal cells of
the epidermis) positive for nuclear AR was higher in cases
(mean6SD, 80.668.63%) than in controls (mean6SD,
65.0619.1%), P= 0.043. Stromal cells in cases showed an almost
2-fold greater expression of AR in the nuclei compared to controls
(mean6SD, 40.0615.1% in cases versus 23.468.68% in controls),
P =0.023. Percentage of AR positive vessel smooth muscle cells
did not differ between the 2 groups. The average of AR positive
cells in the 3 kind of tissues was higher in cases than in controls,
P =0.007
Why AR overexpression is probably playing a key role in our disease has been discussed many times.
Further raising AR or activating it through T/DHT is likely to make you feel worse, though in PFS, there are always exceptions. More severe PFS cases appear to often get worse following androgenic treatments, while certain milder cases (as in mainly some sexual side effects) may benefit.
