I’m trying to figure out what the half-life of fin is, in the event I end up taking 60mg one day and 140mg the next day. How much would this impact the effectiveness of fin working for me?
Finasteride has a 6-hour half-life, however, it lasts in your tissues (hair follicles) at least 7 days or more. For that reason, you don’t have to be exact on taking it, provided that you take a total of 7 mg per week. I believe that you got your numbers wrong as 60 mgs would be 60 times the dose of a standard finasteride (Propecia or 12 times the dose or a Proscare 5mg pill).
