Reconstituting and dosing - accounting for losses?

[graca123]

Apologies for a potentially misleading title, but what I mean by this is that most calculators (at least those that I have come across) provide the exact mixing instructions, not accounting for the fact that the user will not be able to draw 100% of the last dosage, as the amount of liquid left in the vial will be too small to draw in the syringe, as the tip will not be visible / it will be sticking out of the liquid.

Perhaps more experienced users have a way around this, but just curious how do you solve this? Do you add more bac / inflate the strength knowing there will be some loses, or how?

If I reconstitute to 5 mg per 50 units, 50 units will be 5mg. If I do not have enough to exactly get 50 I will make up for the missing with new syringe and vial to not cross contaminate.


As for the remaining amount in vial, you can gently back pin out until you see the tip through stopper and get all but a negligible amount.
