How long until Propecia slows down test hairloss?

I just finished my first week of propecia, started it bout 2 weeks into my cycle after noticing hair loss, how long until I start noticing a change?

i wasnt able to find out how fast it works but,
i'm assuming is within a week, as u take 1.25mg per every 500mg of test u inject, however u must no, propecia is worst than deca as far as shuting down ur natural test, finasteride chemical in propecia will eventually kill ur libido system, talk to ur doc bro......

i'm only doing it while cycling
