So I picked up one of those small fridges. The majority claim they'll only drop 20º below room temp at most, but realistically it's closer to 10º steady. My bathroom catches the morning sun and was already reaching 75º F in early spring, and the fridge struggled to get below 55º. If you trust storage recommendations, anything stored above 40º in a fridge will break down. And for keeping lyophilized vials for the 'long haul,' the claim is you need -40º to -80º (those lab-grade freezers run 5-10k). I came across an interview on the Tubes talking about this exact topic with a lab that specifically tests peptides. Turns out most of those guidelines are total nonsense, written so the industry can CYA. My workplace has a lab for our products where we generate CofA's and GCMS data, but our equipment can't test peptides. The lab manager explained that once reconstituted, vials left at room temperature last at least 30 days, likely 6+ months, and lyophilized vials sitting in your garage are probably fine for 5 years. He also pointed out that if shaking peptides during reconstitution or rough handling destroyed them, humans would drop dead from the slightest bump, and if you saw how most lab samples are treated, it's nothing like the delicate handling people claim. Think about how this stuff gets shipped to you. You're not receiving peptides packed with refrigeration at -40º to your door, and they're certainly not doing that from China to the US or Europe. How long does this stuff sit in a container in peak summer baking in the sun before clearing customs and arriving at your door? You're more likely to contaminate it with bacteria when you pierce the vial, and that could cause problems, than the peptide itself going bad. I still keep my vials in the fridge and in the freezer before reconstituting, but if I were traveling like that, I'd just stash them somewhere reasonably cool away from sunlight and not worry about it.
