if u take something like fina or dutast to save ur hair, how does the dht u are taking work? from what I understand dutast occupies the part of the ar that dht normally occupies, rendering it useless by molecular exclusion. if this is the case how can u take say winny or ast and still have gains. I know winny and mast are dht themselves but they convert into dht partially and exact effectivenes through that mechanism. if anyone can explain I'd apprecite it. thanks bros
