Storage question — reconstituted BPC sat at room temp for 6 hours. Still good?

Lapse. Reconstituted a fresh 5mg vial last night, put it on the counter, forgot to fridge it, remembered this morning. So it was room temp (~22C) for roughly 6 hours in BAC water.

Is this vial compromised? Trash it? Use it? The BAC is supposed to prevent bacterial growth but not peptide degradation. I don't want to trash a $40 vial if it's fine.
