Peptide storage

How about peptides stored in freezer looong term, say 2-5 years?

peptides always lose potency over time. lower temperatures reduce degredation. the only temperature that pauses chemical degredation is absolute zero.

from a practical standpoint, if you use your peptides within a year, refridgeration is OK and nobody is going to notice the 1-2% potency drop for storing a peptide at 5c for a year.

the larger the molecule the more preference you should give towards freezing... gh, and its derivatives come to mind, like CJC, IPA, etc...

GLP1's are large and complex but are actually stabilized because they arent a pure peptide, most have a large fatty acid chain attached to them which actually make them more stable

Counter top fridge for what I’m currently using/reconned. It holds 40° fine.

Lyophilized goes in the deep freezer. Before my inventory got bulky I’d buy hydropeaks and inserts, now I’m going to store kits in their delivered plastic cases in a container, in a cooler, in the freezer.

Are you using a desiccant?

Not in the hydropeaks.

I'm in an "expansion phase" and may move to stainless steel trays with plastic lids that are vacuum sealed for practicality. If they're vacuum sealed, I don't think I'll run desiccant either.

I have several pounds of desiccant... I may make a high temp holder and run some in the cooler everything is going to be stored in, in the freezer.

Overall I'm not super concerned about humidity. The vials should be under a vacuum, and if the vacuum fails, the vial is probably trash anyways.
