follow up i left it out overnight by accident, bin it or use it
reconstituted solution is the fragile part. that is where the cold chain actually earns its keep
parcel sat in a hot mailbox for 5 hours, is it dead
Reminder for private_script_pri: dose day is today. Set 5 days ago.
nobody here can tell you a vial is safe. we can tell you what has and has not survived for us, your mileage will differ
