So I'll be reconstituting my first batch (I'm on 7.5 tirz, have been for a year). I have 30mg bottles from ASC. I also have bac water, in 30ml vials. Do I just add 3ml from the 30ml bottle for my 4-week supply? And throw out the rest of the bac water? From what I've read, bac water is only good for 28 or so days after it's pierced.
