So 5mg (5000mcg) divided by 100mcg = 50 doses per vial.
2. Now no matter how much liquid you add you will always use 1/50th of the liquid for each dose (if you want a 100mg dose)
So if you added 100 gallons of BW to 5mg of powder your dose is going to be 2 gallons (1/50th of 100 gallons).
If you add 1ml of BW your dose will be 1/50th of 1ml which equals 2iu on a slin pin. Why 2iu? ...because 100iu is 1 CC which equals 1ml. 100iu divided by 1/50th equals 2iu.
The amount of liquid NEVER matters. It is the amount of powder that is in the liquid that matters. That is the concentration. You could have a teeny tiny bit in a 100 gallon drum of liquid OR a whole bunch in a shot glass.
If you reconstitute that 5mg vial w/ 1ml of BW then a 100mg dose equals 2iu (1/50th of 1ml).
If instead you decide to reconstitute that 5mg vial w/ 2ml of BW then a 100mg dose equals 4iu (1/50th of 2ml).
