I had a 50ml bottle of NP Pro delivered today. We usually don't get mail delivered on Sundays, packages usually get delivered to our door. However, the package was left in our mailbox in about 85 degree (higher in the sun) for about 3.5 hours before I noticed it. The bottle was very warm, almost hot when I opened the package, must of been over 100 degrees in the mailbox.
Is the bottle still good? How do I verify it's viability?
