To Freeze or Not To Freeze: Lyophilized Peptides

[poolshockguy]

I freeze and take 1 out at a time when needed

By default, I freeze all the ones I am not using.

However, seeing the strong opposing opinions has me wondering...

Fridge for me. I’ve been convinced there’s probably residual moisture in the vials. Plus, as per jano, peps in the fridge should last for years and that’s good enough for me.

I freeze, maybe after I'm done with all of them I'll switch to fridge only. Then reconstitute one at a time

 

[skyepower]

If there's a stock of peps in the freezer, is it too late to rotate them to the fridge?

Or is it that once they're frozen, the only option is to remove to reconstitute, then place in fridge?

 

[poolshockguy]

Just leave until time to use.

Moisture degrades peptides. If the vial contains excess moisture, how is the refrigerator going to stop it from degrading the peptide?

Plus, as per jano, peps in the fridge should last for years and that’s good enough for me.

For properly lyophilized peptides, which do not have excess moisture.

The whole moisture argument is absurd.

Refrigerate peptides. Reconstitute as needed.
