Storage?

Wanting to brew Test Phenp, NPP, and possibly some Tren. whats the best to store them brew them up then put them in a freezer? brew only what i need then freeze the powder? any idea how long they should keep?

I am interested in this as well.

Brew it all if you're going to use it within a coupe years. if you have a lifetime supply brew it as needed. Dark, cool, dry place for raw storage is advised as well.
