So I have 2 pregnyls, 4 ampules, 2 1ml waters and 2 lots of 5000iu powder.
Now 1 lot of 5000iu powder with both the waters(2ml) will give me 20 .1ml shots at 250iu right?

But how do I mix them and store them, I dont think there’s enough space in the powder amp for 2 mls is there? And I don’t think trying to half the powder is a good idea.
So I though get more bacteriostatic water but get 10 mls and make it easy. But the. I thought is it safe to get the water from Amazon?

What’s the best way to do this?
