I actually took a slin pin and measured 1cc of nolva or femara, I can't remember. I shot the liquid in the dropper, I was careful to not let it go in the rubber, if I recall I had to do a slow suck and squeeze method and it took a couple trys.
I took a perm marker and made a dot right where the dropper had the 1cc of fluid from the syringe.
You'd be surprized, usually you pull the right amount out each time.
