From sponsor- NO. I hope you are referring to ampuoles that are supposed to have 1. Are ya sure ya getting all out? Also stand it it prior to breaking neck and run under warm water- some can get stuck up in there. Also draw with a 22 or 23. Good suction. Ones I HAVE seen are always on the mark exactly.
Remember if you pull 1ml of oil into a pin, it will only read .9ml because a full .1ml will be inside the needle itself. If you use a draw needle and don't pull anything out of it (even if you do a tinny bit will be left behind) you will lose up to another .1ml.
A small air bubble pulled into the syringe will clear out the needle and push most of that .1m in, I suggest reading up on this technique before trying it.
If ya that short obviously check exp date and contact sponsor. I never been short on Paki shit. Always on the "1". I do let stand up for an hour at room temp before I score neck and as I said i draw with 22 or 23. Ya still have not mentioned brand name.
