Storing Reta and BAC Water: Room Temperature vs Fridge?

7 replies7 peopleSep 4, 2025☆ Follow
Summary

Can I keep reconstituted reta and bacteriostatic water at room temperature in a drawer instead of refrigerating them?

The original poster wants to store both items in a drawer while dosing 1mg weekly from a 10mg vial over ten weeks. Replies indicate BAC water can stay in a cool dark spot but reta should go in the fridge to limit bacterial growth and maintain stability, with a preference for use within 30 days. Several users confirm they refrigerate BAC water after first use and report no issues when following sterile technique, with one noting they will finish the bottle eventually.

I recently received my reta and plan to start using it tomorrow. Can I store both the reta and the bac water in a drawer, or must they be refrigerated? It's a 10mg vial and I'll use 1mg weekly for the first ten weeks. Any problems expected?

Bac water is okay in a dark cool spot, but I'd put the Reta in the fridge.

It's best to refrigerate. In case of roommates, get a mini fridge for a six-pack and store it in your room.

Keep it refrigerated and try to use within 30 days. The cold reduces bacterial growth risk and maintains stability. Don't leave it at room temperature for ten weeks.

I made a mistake with my BAC water storage. After using it once to mix a vial, I put the BAC in the fridge where it's been for nearly four weeks. Oh well. At least I have two more vials coming.

I store it that way too, similar to why we refrigerate reconstituted peptides. I'll use up the BAC bottle eventually.

Keeping your BAC water in the fridge is okay... Just use it until it's finished!

Alright, that's reassuring! I'd seen advice against it before. I follow strict sterile procedures with vials and syringes, but didn't know the proper storage.
