Reta Question: how old is too old?

[Blueeyedme]

The compounding pharmacies are also selling tirzepatide which holds up very well for months with negligible degradation in tests of both their products and gray market tirz.

Reta is different than tirz. Do you see any 503b pharmacies saying that their reta is good for months?

1. I guess you missed the part where I said we’re NOT talking Reta. 2. Of course there are no 503A/B pharmacies compounding Reta…is that a serious question? 3. Degradation data on both Tirz and Rita is out there from Jano and another source which I’ve seen on this forum.

Based on janoshik testing, degradation is barely 1% a month. I use it up to 60 days if the bac was fresh. When in doubt, filter it. GLP1 peps are quite resistant. I am more concerned about bacterial growth after 90 days.

Using a pen cartridge that was reconstituted back in january, and stored in the refrigerator. By some miracle, I'm still losing weight. These peptides are sturdier than people think.

Especially tirz

Tirz gets stronger after 90 days
