BW sources - what are you guys actually using these days

Been seeing a lot of posts lately where guys are messing up their reconstitution just because they're using garbage water sources. Thought I'd throw out what's been working for me and get some input from others.
What I'm currently using:
- 30ml vials from a compounding pharmacy (local script, easy)
- Backup supply from a well-known online supplier that ships discreetly, won't name drop but you know who they are
- Avoid the small 10ml stuff when you're running multiple peptides, you'll burn through it fast
Storage notes that matter:
- Keep BW in the fridge after opening, obvious but people still leave it on the counter
- Mark the date you opened it on the vial with a sharpie, don't trust your memory
- 28-30 days is the window, after that I trash it regardless of how it looks
- Store away from light, wrap it in foil if your fridge has interior lighting that hits the shelf directly
Reconstitution questions I keep seeing that need addressing:
- Always inject the BW down the SIDE of the vial, not directly onto the lyophilized powder
- Slow push, let it dissolve naturally, stop rolling and shaking peptides like they're a cocktail
- If it doesn't go clear after sitting for a few minutes, that's a flag worth paying attention to
Anyone sourcing domestically with consistent quality, drop your method below. Not asking for specific vendors, just the channel. Compounding pharmacy route is underrated and more people should explore it if they have access.
