how long is fina good for?

[Fashioncore1]

I am in the process of making my fina using mr. t's finakit.
I am going to use this batch in March, but was wondering if i made another batch, how long can i keep the finished product sitting in my safe? I am getting married in October and don't want to be playing pharmacist in my house with my wife around. she doesnt care what i take as long as its out of her site.

couple of mths..
keep it dry and out of the heat....
but it really depends on where you keep it..
