Quick clarification:
I have a 10mg TB500 vial. I wish to do 2.5mg (25 units on a 100 units insulin needled) twice a week for 4 weeks.
To reconstitute the TB500 effectively to get the right dosage, do I reconstitute the 10mg vial using 1ml of BAC water?
mg/ml
So, 10mg(TB500)/1 ml bac water gives you a ten to one ratio.
How many mcg do you want to administer per dose?
-Ok, you already gave me that info. dose: 2.5mg
-It's better not to preload your slin pin, just draw from the vial with a new pin each time.
-Therefore, 2.5 Bold Graduations (there are ten on a slin-pin) will give you a 2.5mg dose.
-You were on the right track. This sort of thing is uncomfortable for me as well.
-One concern, the amount of bac water you add shouldn't be based simply on the dosage you wish to administer. Some substance have a range of dilution based on the physical properties. Under-dilution can lead to a failure of the substance to fully dilute and leave crystals behind. I don't know the requirement for TB500.
I usually reconstitute a 5mg vial of TB500 with 1ml of BAC water. So you are correct 25 on an insulin syringe.

Yes, I was referring to his dosing being correct for a 10mg vial. I should of been more clear. I usually purchase 5mg vial and inject .50ml.
