The ratio is personal preference. Obviously, the more bac water the more accurate your dose, but I prefer to shoot less. My stuff comes 5000iu/mL. So I leave it that way and just pin .1mL (500iu).Originally Posted by roastchicken
As for the storage? I can't really say... I'm not an expert on that. When I had pregnyl, I just drew it up and shot it into a sterile 10mL vial. I do believe some guys draw it into one syringe and just change the pin when they shoot.
