Wegovy delivery delay - temperature?

[DirtyBroomstick]

Hello,
Finally gave myself a push and ordered two pens from a reputable site. Advertised as Tracked24 with Royal Mail but seems there's a little delay. Before I email the seller, just wondering how long the pens are effective for if they're stuck in transit? I know they're packed in stuff to regulate temperature. Would they still be okay if they came after 3/4 days, or do I need to try and organise a replacement if they don't come before then? I've seen some sites say unopened pens must be refrigerated and other that say they can be at room temp for up to 28 days even if unopened, so a bit confused. Anyone have any experience using an unopened one that wasn't chilled? Thanks.

I thought that it was 56 days. So if you start using immediately it would be fine. I've had a 24 hour delay thanks to Royal Fail, but the liquid in the pen didn't look cloudy and it seemed to work fine.

Thanks

I had a 4 day delay with Royal.Mail. The pen was fine but as it was at room temperature I think it would only have lasted 56 days before it went off.
