Well, I could not put my hands on a prodcution/clearnace value for
adrenaline...it's a rather tricky thing to describe, since not all
adrenaline is exceted into blood or unrine were you could easily measure it
in a human subject.

Maybe the next best thing would be the amount of adrenaline in the blood at
any given time.

That number is about 0.1 nmol/L of blood. Given a molecular weight of about
183g/mol, 5 liters of blood, that works out to a total amount of adrenaline
circulating of 0.000002 grams (or 0.2 micrograms)...still not very much!

Hope this helps.
