RU + fluridil
spironolactone is ok if you are also on finasteride since it works well against testosterone but is weak againts DHT. You need to take action against the effects of DHT.
fluridil has zero side efects guaranteed, but does only a partial inhibition of the androgen receptors, not 100% since this is very hard to achieve.
Ru is good but expensive and a bit hard to get.
you can try spironolactone + fluridil and finasteride 1 mg per 3 days., to start.
Try reducing finasteride until the sides clear up. even if you reduce DHT by 30%, that will be of some benefits in combo with the aftermentionned topicals.
