Which part?Not being sarcastic. Serious question. Why do this?
I am more talking about equalizing the pressure so it doesn't shoot GH all over the place when you remove the syringe when drawing. You would be surprised how many people do this lolI feel like I’m missing something here. What is the intent of removing the vaccume? To make it easier to draw?
Doesn’t not being exposed to outside air help keep the hgh sterile and safe?
