One explanation of why I started having hot flashes a week after starting Casodex could be low normal T. Also the residual hot flashes after last Lupron shot in April 2017 did not go away completely.
You are probably correct on both points. I too never had T tested before HT and mine is slow to recover and was probably low to begin with. Hopefully the ADT2 will keep your cancer in check. Good luck!
