My vial's potency report made me rethink summer shipping

I'm not a lab person, but I do keep a sticky note on my fridge with arrival dates. My last shipment sat on the porch for three hours in 91-degree heat before I got home. The ice pack was mostly water. Now I see folks sharing private lab numbers on Reta and how much potency can drift, and it makes my stomach flip a little. Our one-stoplight pharmacy is great about insurance and refill reminders, but they don't test anything — they just hand over the box. I've started writing down batch dates and keeping a thermometer in the fridge door, which is about as fancy as I get. Has anyone else had a delivery get warm and then noticed the medicine felt different? Or am I just overthinking a melted ice pack?
