Question for those with more experience:

Once a peptide has been reconstituted with bacteriostatic water and properly refrigerated, how long do you personally consider it stable and usable?

I often see 28 days mentioned, but I’ve also seen people say 6–8 weeks or longer depending on the peptide.

Curious what everyone actually follows in practice and whether you use a general rule or base it on the specific peptide.

Further to that, once a vial of bacteriostatic water has been opened and properly stored, how long do you consider it usable before discarding it?

Thanks for the info!
 
I use it until it's gone.

I, personally, am comfortable with at least 90 days for the bac water in my reconstituted vials. But I suspect longer is ok, even though I haven't had any need to push longer than that. My vials are empty before 90 days.

There are peps that I wouldn't use 90 days though, but that's based on the peptide not the bac water.

I have a family member who have let a vial of tirz (reconstituted with bac water) sit in the fridge a year (he switched to reta and didn't throw out the tirz vial). Then his wife decided she wanted to try a glp, so she injected that year-old tirz in bac water... it worked, she finished out that vial, and she lived. I'm not suggesting you try it.
 
I think there was a study on this and except for few peptides, most of the stuff do last a long time as long as oxidation is under control.
 
Most GLP's are very stable and will last a long time. I have used a vial for 2.5 months with no noticeable degradation.

As far as the bacteriostatic water is concerned, I am currently still using a Hospira Bac water that I opened on April 30th and just reconned a vial a couple of days ago with no issues. I will use this bac water until it is empty, currently has about 25% left in it. As long as it is kept away from light, either in fridge (I keep mine in a cupboard in the kitchen) and is clear with no floaties in it, I consider it still usable.

I use it until it's gone. So far I haven't had to use one longer than 9 weeks.

Here are some test results

The 503A place where I used to belong would mail 3 months of reconstituted Tirz out at a time. 3 vials of 15mg. Some BUD dates were 6 months out. While others were set at a BUD of 90 days. Plenty of users purchased the largest doses and took way less titration to make the drugs last longer. I know some of them went beyond the 120 day window on the final vial and they never reported issues.
 
Until hairpins get seasick on permanent waves. (One of a few amusing farewell notes on my mom's 1950s high school yearbook.)

3 months, with bac water, vigilant alcohol-swabbing, and refrigeration.
 
Tz and Survo are gone in 6 weeks.

GHK-Cu & KPV - daily dosing - I toss what's left after 45 days.

I always check the vial to be sure it's clear. If it isn't or if floaters, I bin it.

Have you had a vial of Tirz turn bad in 45 days? My Reta has never done that, but I also filter. Even when I first started and didn't filter, I don't remember it getting cloudy or floaters.
 
I doubt I will ever have a reconned vial that I would toss…I do put a date code on a vial when I recon but it’s more so I can try and figure out what vial killed me if I expire…I’m curious like that…
