Bump

3. from what I understand......(i could be wrong)

1iu = 10mcg..... so how many mls depends on the concentration of the compound..

for example if you've got IGF @ 1000mcg/ml then 1 iu = .01ml
so a 60mcg dose of this particular IGF would be 6 iu / 0.06ml

This is what i understand, but as I say I could be wrong....? anyone?

4. if its 1000mcg suspended in 1ml then each iu will be 10mcg.

5. I found this table; does this help?

Ratios and Percent Solutions
1:100 = 1g/100ml [10mg/ml] = 1%
1:200 = 500mg/100ml [5mg/ml] = 0.5%
1:1,000 = 100mg/100ml [1mg/ml] = 0.1%
1:5,000 = 20mg/100ml [200mcg/ml] = 0.02%
1:10,000 = 10mg/100ml [100mcg/ml] = 0.01%

There are 1000 mcg to 1 mg

"Unfortunately, for measurement with a U-100 syringe, the dose must be converted into insulin unit equivalents so if prescribed 20 units of Symlin (which is 120 mcg)"

This means 10 units on a slin dart = 60mcg and if you're using a U-100 dart then there's 600mcg (right?)
See picture of chart below.
