Peptide Storage

[borchev]

I have some retatrutide and ghk-cu I don’t plan to use until February. Should I keep them in the fridge or freezer? What about ghk-cu that I probably won’t use until a year from now?

throw it in the trash

If you can put them in the freezer if its lyophilized. Wont harm. Avoid taking them in and out too much tho.

If reconstituted, dont freeze it.

Why is it bad taking them in and out too much? And is it cool if I move it to the fridge when I constitute it?

Let me cope in peace

well: each time you open the vial, or even just let it warm up, a thin layer of moisture can form inside the vial or under the rubber stopper --> the powder starts to partially hydrate unevenly

-repeated freeze–thaw or warm–cool cycles stress the peptide bonds, nd reta and ghk-cu are pretty sensitive, so this can cause slow denaturation or aggregation

-also every handling cycle slightly increases air (and thus oxygen) inside the vial --> oxidative damage, particularly problematic for copper peptides like ghk-cu

also, you should be fine when putting them into the fridge. dont like juggle them around and shake them
