Unconstitued Reta Freezing Yes Or No

[Phatmax]

Hi all I'm getting mixed answers on this and now not sure if i have unconstituted raw Reta how is best to store it I've been told to freeze it in Ziplock bags until I need it reconstituted then once its reconstituted keep in fridge?

thanks for your help as always guys.

Yes, unreconstituted retatrutide and other GLP-1s are best kept in the freezer (any one, including household ones with autodefrost) for longer and more sterile lifespan. For up to several years. You don't need any special kind of bag or box, although if your area is prone to blackouts a thermal container with icepacks would be helpful to avoid big thaw/freeze swings.

When you say "raw" do you mean a lyophilized kit?

I am not sure how there could be mixed answers as to whether lyophilized peptide vials should be stored in the freezer. The universal answer should be yes. Reconstituted vials with liquid should be refrigerated and is not necessary to freeze a lyophilized vial if you plan to use it in a month or two. Perhaps that is where the mixed signals came from?

Good question! I always assumed “raw” would be pure reta devoid of fillers, which I’ve never seen but if you had a connection at the factory, I suppose it’s theoretically possible! I’m guessing Phatmax is asking regarding what we all know and love - the lyophilized variety ready to recon and pin.

I would guess that they have seen some of the more in depth posts that I have seen regarding acutal storage temperature requirements as they relate to glass transistion temperature. Where depending on your specific peptide and its specific Tg you could be cycling through that value multiple times in a regular freezer, which is a bad thing.

But then you realize that we don't really know enough about our particular peps so we don't even know what the Tg is anyway.
