I just got a few kits of blues. When mixing them with bac water as soon as I stick the pin in the vial it sucks out the water without me doing anything. It is like a bag vaccum inside the vial. Then the mixture gets real cloudy and there is some foam @ the top of the mixture. I never had this happen with any hgh while mixing.. It seems there is a big vaccum inside the vial. I hope this doesn't hurt anything.. Is this something I need to worry about... thanks..
