how long can i keep a pre mixed shot of h

[vision conquest]

I am sorry if this has been covered but I did a search and could not find any information regarding my question.

So I mixed up a quarter of a gram of h, split it into two shots, I had one and I have the second one in a fit.

My question is this, how long would it be safe to keep the second shot, obviously I wouldn't be keeping it for a long time but I may hold on to it for a few days if that is safe.
The water I used to mix up was just tap water which I boiled, unfortunately I could not get bacteriostatic water.

Do people think I am pushing it to try and keep a shot this long?

The longest I've ever kept a premixed shot was 30 mins. Otherwise, don't know. I'm terrified of bacteria, so even 30 mins was way too long.
