I assume these numbers are for hormonally treated cows? For organic
milk this would be more like under 2000 nanograms, right? How much
of that survives digestion? How good is the human feedback system
for IGF-I ? Notice that 2,500 free IGF-I and a much larger amount
of bound IFG-I indicates that our bodies might be able to keep a
very tight lid on the free IGF-I and bind it if it exceed an
appropriate amount. If that's the case, why worry about it?

If it's still in milk, then it's still in your gut waiting digestion.
Why worry about that? If it's not still in milk, then it is no
different from IGF-I from any other source, and will be mopped up
by your body very quickly.
