Finasteride

I read on a previous post that if you take finasteride you can experience a shedding of the hair after about 6 months of use as the new hair follicles come through. Thus you shouldn’t stop taking the finasteride. However, I would only use finasteride in order to slow down MPB that could be accelerated by a steroid cycle. If my goal is to do this then how should I take the finasteride i.e. all the time, only when injecting, how long after my last injection etc etc because I don’t want to have to use the stuff all the time, ideally only when “on”.
