In the process of moving I seem to have lots my proscar supply. I ordered some more but it will be 2-4 weeks before it gets here. I am in the middle of a t400/eq cycle and was taking it not to lose my hair. I took it for 2 months before the cycle too. How long can I go without taking it before the medicene wears off?? Does anyone know any online pharmacys to order proscar from that ship quickly??? Thanks.
