Finasteride (Propecia) is obviously used to prevent hair loss due to its ability to inhibit the enzyme that converts testosterone to DHT. My question is, if you use it from day one of your cycle as a preventative measure, how much will it impact your gains?
If it inhibits the potency of your cycle by a significant amount, would it still be effective if only used immediately when hair loss begins? This seems tantamount to having Nolva on hand for immediate use during the cycle if Gyno arises.
