Interesting. Even the Pharm grade gh I have used has always come in powder form and needs to have a solvent added to it. As far as your math goes, you start out right but then things are a little off . Each vial is 10iu of gh. Thats 10iu no matter how much bac water you add. Follow me? What I would suggest doing is adding 1ml of water to each vail. So if you have 10iu of gh per vial and you add 1ml water, 1/10th ml would equal 1iu of gh. So from there you can figure out how much you want to use per day. Also, I would suggest you only mix one vial at a time. Once gh is mixed, it’s less stable and over time will break down.
