I dont mind about weakening the dose, I would rather have a slightly lower dose and be safer with sterility.
I have at the moment one vial with 2ml in it, but I have about 12 rediject so 12ml to go into vials.
With the 2ml already in the vial, I was going to filter it into a new vial and add BA to it.
With the rediject pens I Have, I was just going to transfer straight to a vial and add BA to it, as the redijects are sterile?
Do you know how much liquid you lose to the dead space in the .22 filters?
