Depends on your genetic make up, maybe a year. Good to be on the pathway taking the pills/injections but your life will be changed in so many ways, be careful see a gender councilor first as you will lose all male sexual function and your brain changes, you do not turn into another person just flooded with new emotions and situations to handle it is hell sometimes. Good luck and find support.
