Dropping finasteride dose

I’m currently on 1mg oral min & 0.5mg oral fin. If I drop the min to 0.5mg, will I retain the gains made? I have been on my current protocol for about 8 months.

The 0.5mg dose is 80% as effective as the full dose of finasteride. So yes, you can drop the dose and probably will not see any problems from doing so
