So basically i left 2 viala of tren e in my car overnite, and i live in canada so in the morning they were botb freezin cold, the liquid wasnt actually frozen. I left it in room temp for a day, both vials looked the same, same colod and no visible crystals inside. So just to be on the safe side i heated up the vials for 7 mins ( just let thr vials sit in hot water). Left them in room tempt for another day and now one vial has a slightly lighter color to it. Still no visiblr cryatals or anythin r both vials still good?
