BAC water shelf life after opening?

I've gone about two months on an opened vial here in Toronto and it was still clear when I finished it. Dating it with a Sharpie like the others mentioned is what I do too. Anything cloudy or with floaters gets tossed regardless of age.

Mine lasted about six weeks once and stayed clear the whole time, so a few weeks in the fridge doesn't worry me anymore. I write the open date on the label now too since I got tired of guessing. If it ever looks cloudy or has anything floating in it, out it goes.

I've stretched one to about five weeks before it ran out and it stayed clear the whole time. Dating the vial when I puncture it has saved me a lot of second-guessing too. Mine's been clear, but if it ever looks off I'm not risking it.

Mine hit about two months once before the vial ran dry and it never turned cloudy, so a few weeks in the fridge wouldn't stress me out. I Sharpie the puncture date on mine now too. Anything off-looking gets dumped regardless of age.

I've gone about six weeks on one and it was still clear when it ran out, so at a few weeks I wouldn't panic. The Sharpie-on-the-vial trick changed everything for me too, no more guessing games. Clear and no floaters is my green light, anything weird and it goes straight down the drain.

A few weeks is well within what I've personally used without any problems. I started writing the open date on mine after going back and forth too long over an older vial, and it made the decision easy. If yours is still clear with nothing floating in it, that would settle it for me.

I've gone well past a month on mine before without any trouble, but I always mark the open date so I'm not guessing later. Mine stayed clear the whole way, and I toss it the second anything looks cloudy or has floaters. For me the appearance check is what decides it.

I've stretched mine to around five weeks once and it stayed clear the whole time, so a few weeks in the fridge has never been a worry for me. Date on the label and a quick visual check before drawing is my routine now.

I've used mine past the month mark a couple times and never had an issue, but I date every vial the day I open it now. Clear and no floaters is my go signal too.

Two months was my longest stretch and it looked fine the whole time, but I stopped pushing it once I got serious during my 67 lb loss and just date and toss at 30 days now. The peace of mind was worth wasting a little BAC.

I date mine when I open it and toss at 30 days now too, but honestly the longest I pushed one was about six weeks while working through my reta vials and it stayed clear. Since I'm down 20 lbs and finally in a good groove, I'd rather not risk it for the sake of a few bucks of BAC.

The date-on-the-vial habit is what got me through my own swap too, can't recommend writing it down enough. I also started a touch lower than my brand dose and it made the transition way less stressful. Only 7 lbs in so far but no issues with the compounded stuff yet.

I never pushed past 30 days myself once I started dating the vials -- before that habit I used one maybe five weeks in my Jacksonville heat with zero visible problems, but I figure the few dollars saved isn't worth wondering if my semaglutide is sitting in sketchy water. Thirty days and toss has worked fine for me across this 31 lb stretch.

I mark mine with a sharpie the day I crack it open and toss at a month now, though back before I got in that habit I ran one closer to six weeks and it looked fine. Down 21 lbs and I just don't want to gamble the progress over a couple bucks of water.

I'm on the pill version so I skip the BAC headache entirely, but the sharpie-date habit stuck with me anyway for anything in my fridge down here in Miami heat. For what it's worth I never pushed past a month myself, and tossing a few bucks of water beats second-guessing every draw.

Mine sat in the fridge well over a month once before I wised up, and nothing seemed off, but dating the vial now and dumping at 30 days has been my move ever since. Down 29 lbs and honestly the peace of mind each draw is worth more than the few dollars of water.

I keep anti-nausea candies in my bag for rough mornings. Eating slower than I ever have has fixed most of my GI issues. The GERD flared with my first bump but settled after a week.

This is what showing up looks like. This is the good stuff right here.

I date mine with a Sharpie when I open it and toss at day 30, same as you're describing. Used to stretch one to six weeks before I started labeling, and once it's written on the vial there's no more second-guessing at the fridge. BAC is cheap enough that 13 lbs in, I'd rather not gamble the vials it's mixed with.

Sharpie date trick sounds way better than my method of squinting at the fridge and hoping I remember. I've gone about five weeks past opening without issue in my AZ kitchen heat, but I do toss at a month now, mostly for peace of mind at 1mg. BAC is a couple bucks, not worth the what-ifs.
