does freeze dried tirz/reta need to be kept in a refrigerator

[phosphorylation]

if it's not reconstituted and still in powdered form, is it okay to store it at room temp for months/year

or should i keep it in fridge?

The lower the temp the less chemical degradation..

is it necessary/ can it degrade when it's not reconstituted though

My understanding is that while it will degrade at room temp when in lyophilized form, it will last 1-2 months (but you dont know the degredation that has already taken place, since it was made) - but it is ideal to freeze it as it will last many months.

EDIT: Didnt realise the link was to a site selling things. My b.

Yes. All lyophilized peptides contain moisture.

You can't see the difference between a batch containing .5% moisture and 4%. UGLs certainly don't have quality control or instruments in place to ensure it's the proper level.

4% will degrade 15x+ faster than .5%, the difference between weeks and a year until meaningful breakdown. Both will degrade more slowly the lower the storage temp. So that's the safest way to minimize degradation.

For long term storage, you want to be freezing at -20C to -80C. This will give the most stability. You also don't want to be using a freezer with a defrost cycle. This should give you a reasonably stable storage out to 3 years, after that... My bet is it will be fine for a few more years if anyone wants to run the tests.

You can ship fine but there may be a small amount of degradation. I would be willing to bet most sources and manufacturers aren't freezing or refrigerating after manufacture and its sitting around months with minimal degradation.

I hope people test their stuff if they are doing long term storage.

would be a shame if someone spent 800 dollars+ on a freezer just to be storing nothing lol

Pretty sure Janoshik posted some testing results for HGH awhile back and a number of people have dug into it on Peppys

my point is, there are people who buy 5+ years worth of peptides. Then they never test their peptide is what it is lol.
