Storage question about storage and cold: my pen was left out of the fridge for 18 hours.

This is my experience too, for whatever a second data point is worth.

Cold chain shipping for storage and cold: my last order arrived with the cold pack completely melted and the vial at room temperature. I contacted the vendor and they reshipped with better insulation.

What to look for in shipping: temperature monitoring strip inside package. If your peptide arrives warm, contact the vendor immediately. Don't assume it's still good.

No disagreement, though it depends on where somebody is starting from, and this thread has been assuming a starting point nobody stated.

This answered a question I did not know how to ask. Adding it to my notes with a link back to this thread.
