Hi, I'm going to betaking part in a medical trial next month and I'll be in a facility for ten days. Obviously while you do these you're not allowed to be on any medication and if you have anything in your system you won't be allowed to take part.

I've looked online but struggled to find a definitive answer, does anyone know how long after ingestion Finasteride can't be detected in your blood or urine, the same for Minoxidil, thanks.

You have to wait months after stopping fin to be able to donate blood, so I imagine it stays in your bloodstream a while?
