I know your not supposed to so I wouldn't ask them - I'd just tell them I had some leftover that is still in date. I used some leftover Menopur this time that had expired in February. Still worked OK for me... I just assumed that they have a meaningful expiry date based on real deterioration timelines BUT with a healthy margin of error thrown in, and I assumed 2 months was within that margin of error...

Haha it’s so expensive! I had to buy another vial of Menopur. So far I have enough Gonal F. I do have a leftover box from last year, expiry was in January 2018. If I end up needing another vial I’m hoping they will let me use the expired one??
