Finasteride vs Propecia

[redy]

So, I know they have the same active ingredient and dosage for 1mg and everything,

however, as I'm coming to the end of my first bottle of what I realized was generic fin from CVS (on prescription) I would like to know if anyone has realized a difference in effectiveness?

It would only be in binding and inactive ingredients.. since it's from CVS pharmacy, is it understood to be trusted to work?

I just want to make sure all my boxes are checked and I'm giving myself the best chance, as I've already started to get some faintly colored vellus hairs from the "big 3"
