Freezer storage success with my latest batch of BPC 157

Posted by kineticmind in Reconstitution and Storage

I am so stoked right now because I finally figured out a solid system for keeping my lyophilized vials organized in deep freeze storage. I used to just toss everything in a drawer and hope for the best but my recent assay results show zero potency drop after three months of proper minus twenty storage. Keeping them away from any frost buildup and using vacuum sealed bags changed the whole game for my workspace. My lab partner thought I was being way too extra about the humidity packs and temperature logs but the data speaks for itself. The powder looks just as fluffy and intact as the day the courier dropped it off. Just wanted to share this win because proper storage really does protect the integrity of your research materials so much better than standard fridge temps.

I need to step up my lab management game because my current setup is basically chaos.

Are you storing them under a full vacuum seal or just standard ziplock bags with silica packets inside?

What kind of freezer are you using out of curiosity? A chest style or just the regular kitchen one?

That is seriously dedication. Do you let the sealed bags come all the way to room temp before opening them up to avoid condensation?

I am using a food sealer on a gentle setting with food grade oxygen absorbers and two small silica gels per pouch.

Oh absolutely yes. I leave the sealed pouch on the bench for at least an hour so moisture never touches the cold glass.

Kitchen fridge freezers tend to have frost cycles that fluctuate temps wildly so a dedicated unit is smart.
