I don't know if there is a hard and fast rule, but I keep 20% in the fridge
for around 6 months or until the little bits start to form on the bottom.
4% I would never keep that long, maybe a week at most.

Best if you want fresh, small volumes, all the time is to get those little
37% ampules and dilute as necessary

I am very interested to hear other folks opinions too, as I am sure they
will vary!
