100mg reta vial

Hi all,

I ordered a 60mg reta vial but the supplier sent 100mg instead.

I'm wary of the shelf life once reconstituted, I am planning on using 2 or 3 ml of bac water but at 5/7.5mg/weekly I think the solution will go over the recommended life.

As long as it doesn't turn cloudy or look off, should I just continue to use it until empty?
