Thats interesting, idk the similarities or differences in our meds and obviously im not a doctor but you are the first person to mention this breakiing down problem. Maybe its more likely for valerate??

But cypionate (what im on) seems to be shelf stable for years. The consensus ive been hearing is when its open its good for about 6 months safely. Ive heard mention of people going longer, but those are outliers and most agree 6 months is a good rule. I believe at my dose 6 months would make an empty vial.

You have the same concerns i have. I see stories every so often on here of people struggling to get doctors, clinics, pharmacist, psychs etc etc to believe in their transness. Some people it takes years! So i does hurt to throw it away.

Which is why ultimately i wont be doing that. Might use till gone and build a backstock, might donate. Idk yet.

Like i said, not a doctor, but if youre feeling and thinking the same as me then i say its worth doing research into it and seeing if there is something you can do. ❤️❤️

So, again, coming at this from a diabetic perspective, ya might try researching around or talking to people from other countries about this.

I had heard similar for insulin in the US. If its unrefrigerated, it will most likely go bad after about a month, but I had heard in the UK and some of europe, their guidance says 60 days.

The other thing is: thats for unrefrigerated. I'm not sure what ya'll are taking and if it has to be kept refrigerated or not like insulin does, but for insulin, if its kept refrigerated, even as you're using the vial, it will last muuuuch longer in the fridge, like years.

Take all of this with a grain of salt because if I have a bad vial of insulin, I can tell immediately with diabetes as my blood sugar will start to sky rocket, and I can correct it with other insulin I've stockpiled.

If your medication starts to go bad and you use it, I'm not sure how that manifests and how harmful that will be to your goals with going trans.

You know home brew HRT vials? Those are made by folks in labs they set up in their basement. They're able to make vials for a couple dollars. The home brewers usually charge $50+ for a vial, but most of that cost is just finding a way to get it to you without revealing the identity of the seller. They have to use really elaborated and convoluted shipping/reshipping methods.

But the actual pharma companies? They have even better economies of scale. No way it's costing them more than a few dollars per vial. If random STEM nerds can do it in their homes, I'm sure they can pull it off.
