Generally you would get 2 5000 iu vials, taking .250 that lasts 40 days or 20 days per vial. Note: Dont mix both at the same time, only mix as needed.
That is 5000 divided by 20 gives you .250.
.125 * 40 gives you 5000 - So you would only need one 5000 iu.
However, I am not sure where you got your dosage amount from. If it is Dr. S's manual, he states that they were using a different mixture because of the syringes they were using.
Most clinics and doctors state to start at 250. This gives maximum hunger satisfaction.
I hope this helps.
