With hormone therapy PSA reduces to a very low number for most men, with at least some reduction after the first few months: if one product is not effective one of the alternative medications will usually work.
Not everyone experiences any of the POTENTIAL acute side effects: there are reasons why older men often do no have side issues.
Tests should be done to measure hormone blood levels to check that the medication is doing what it should be.
Have you read the publication by Dr Myers on the subject ?
To my mind it's essential reading for anyone interested in hormone treatment.
