I personally would calibrate the open vial on a scale to make it read Zero with the vial on the scale...then just cut a small corner off the ziploc baggie or whatever, and slowly squeeze the goo into the vial until it reads 6g exactly. This is one way....
The other way is...
Put the stuff into the fridge for a bit to get it to solidify a little bit (this wont harm the hormones) and use a clean butter knife and just whittle bit by bit off into the calibrated scale with the vial on it
