reading a syringe

[timbostocklt]

Can any one tell me what 2.5 mcg looks like on a 1 cc syringe, it's labeled .1,.2,.3 etc

It sounds like a mistake somehow.
Usually the dosage is measured in either units, or a decimal portion of a ml.
In a 1ml syringe, you'd expect to see from .1 to .9 ml dosages.
My wife takes thyroid medicine measured in mcg as opposed to Viagra which is measured in mg.

I ml = 1,000,000 mcg of water. However, a milileter is a unit of volume whereas a mcg is a unit of weight so a ml of different substances would have different weights. A syringe is calibrated in units of insulin. As far as insulin is concerned, 100 units = 1 ml or 1 cc.

To calculate the amount of a substance in a unit you would need to know the amount in mgs/liter the substance represents. If the substance contained 2.5 mcg per ml, you would need 100 units of the substance to get the full 2.5 mgs. If you injected 50 units you would receive 1.25 mgs.

Where is Jimstars when we need him.

I know that Timbo said he was using 3 mcg of PGE-1 (Caverject system).

I had questioned if that was really how much he was using as there is not even a number below '5' on one of those dial em in Caverject syringes.

So, moving from that premise, it is caverject mixture which would normally be maybe 20 mcg in 1 ml of water. BUT .. you have to remember that everything on Caverject system refers to the DELIVERED AMOUNT of PGE-1 and NOT to any ml or unit volume. Supposedly that is to make things easier to comprehend.

That 20mcg/ml would be 1mcg/.05ml (or 1 mcg/5 units).

So from that you can quickly multiply your mcg x 5 to get any total units to draw in the syringe (2.5 x 5 = 12.5 units).
