Switch to generic meds?

I’ve been on Hims min and fin for like 2 years now. Fin 1.2mg and min 3mg. If I changed to generic the dosage would be fin 1mg and min 2.5mg. Do you think I would see much of a difference with those changes? I’ve mostly just been maintaining and haven’t seen any regrowth, I’m cool with just keeping what I have at this point
