Fina carts.... refrigerate or room temp?

Two questions:

I have my carts and now I am waiting for my kit. Should I keep them refrigerated or at room temperature until my kit arrives?

Also, does converting them to injectible extend the expiration date of the tren? I've heard it lasts longer in an oil base...

you can leave it room temp or in the fridg......... it's exsessive heat that ruins them.

I don't know if after the coversion if it extends the expiration I would assume it would still be the same but not sure
