Tirz powder storage Q's

Freeze-dried tirz powder stores at room temp until reconstituted - fridge once mixed. Standard guidance is 3-6 months in powder form if sealed and away from light.
 
Freeze-dried tirz stores best at -20C in an airtight container with a desiccant - the Hydropeak approach works, but shrink-wrapping adds a moisture barrier worth having for anything held over 6 months.
 
Working with the lyophilized form directly is unnecessary for any standard protocol - reconstitute in the original vial, then transfer to storage vials if you're splitting doses.
 
The storage time question is one of the hardest to get a clear answer on because you're right - the shipping condition uncertainty is a real variable that no one can fully account for. Basement dark and cool is better than room temp with fluctuations. Most people treat the shipping period as the main uncertainty.
