Reconstituting BPC-157 with bacteriostatic water, do I really need to use it all at once?

Right, so I've finally got my hands on some BPC-157 and a vial of bacteriostatic water, and I'm trying to get my head around the reconstitution maths before I pin anything.

The bit that's throwing me is the multi-dose side of things. If I reconstitute a 5mg vial with 2ml of BAC water, that gives me 2.5mg per ml, yeah? So each tick on a 1ml insulin syringe would be 0.025mg or something close to that depending on the dilution I land on.

But here's my actual question. The vial says the peptide is stable for a certain window after mixing, and I've seen wildly different numbers floating around. Is it actually fine to keep poking into the same vial for two or three weeks, or am I being a bit daft and should just mix what I need on the day?

I'm going slow because I don't fancy wasting a whole vial on guesswork. If anyone can talk me through how they store the mixed vial and for how long, I'd proper appreciate it. I'm in the UK so fridge storage is easy enough to sort.
