Storage Times

[Ryty2266]

What’s the recommended max storage time in the fridge for the raw Tirz and Reta vs the reconstituted vials?

They will last longer in the fridge than at room temperature but they last for many years in the dark in the freezer.

As per STG Reconstituted frozen reta degrades 14% after 45 days at room temperature. Reconstituted and refrigerated reta degrades between 3-5% over the same 45 days and 9% after 90 days. Unreconstittued peptide in freezer will last for years. Overall reconstituted reta should most likely not be refrozen as it is reported that the ice crystals damage the peptide. A single freese thaw cycle destroys 4-14% of the peptide. The exact number varies depending on researcher. It appears that tirz is a much more stable peptide

Have you got a source / link for that degradation percentage for reta? I am not disputing it just curious as I would have guessed it was lower based on some data from other peptides, but it is definitely possible that one peptide could degrade faster after freeze thawing. Freezing it might still be a valid option if buying large dose reta vials and on a low dose after splitting it up into multiple vials. A dose of say 2 mg would only change by a max of 0.28 mg after a 14% freeze thaw cycle loss. Still probably makes more sense to buy smaller dose vials if on low doses long term.

Storing powdered tirz in basement in a dark box. Any idea if it last's a year? Everything i read about storage times feels confusing since no one knows if it was 14 days in 30degrees celsius during shipping or 8 month on the shelf at manufacturer / vendor.

If the recon'ed solution is clear and effect is working all is good?

Yeah, who knows what happens after the manufacturing process. I serious doubt that vendors are keeping kits in refrigerators never mind freezers. And then there is the shipping time, where the peptides are exposed to shipping temperatures.

I asked AI and here is what AI suggests is the expected stability time frames. I think that this will vary based on the peptide and manufacturing process. But provides at least a framework to consider.

yeah i probably f*ked up.. bought a kit, went super smooth. Got carried away and bought 3 more and now i got tirz that'll last 4 years on my current dose.. (4mg so still low)
but it still cost less than a 15mg kwikpen so.. win?

I read at room temp, dry powder Reta last 1 -1.5 years.

I think there was a video from Janoshik floating around that said lypholized peptides were fine in the refrigerator for 2 years easy. Something like 5-10 in a deep freeze. Even in a dark corner was decent like 6months or longer.

And this doesn't mean they are bunk at these times but degradation has set in.

Interesting! I've gotta look this up now.
