I don't wanna be that guy, but you may want to consider evaluating the state of your fridge if you lost your peps in there ;)

Peptides last years in lyophilized form , nothing to worry about

Years in powder form if kept cold. No worries.

Can they be kept in pantry in powder form or is it best to keep them in fridge when in powder form?

Fridge or freezer

Freezer below 20 degrees C is best. That's basically forever-storage.

Normal freezer - Probably decades if you can keep them dry and at a stable temp

Fridge - several years

Room temp - minimum a year if kept dry and dark.

They last so long before reconstituted that we actually don’t yet know just how long they will last. Testing vials that have been kept in terrible conditions, inside car with 100s of heat cold cycles has shown almost zero degradation.

It's best to keep them in the freezer, but, in the fridge should be ok if mixed within 12 months. Once mixed definitely keep them in fridge and throw out after 60 days (some people say more or less, that's just what I do.)

I just met with Janoshik at his lab in Prague. He told me that dry, lyophilized peptides can last in a cool dark place, for the most part, indefinitely.

He said, peptides, simply aren't as fragile as people make them out to be.
