Normally, YES. The effect on IGF-1 is also heavily dependent on the level

of

Insulin. Low Insulin can cause very little increase due to production of

IGF-1

binding proteins which will convert most of the IGF-1 into the inactive

form.

High Insulin normally inhibits GH release as these two hormones normally

don't

exist at the same time.

CRing normally lowers Insulin, which increases the release of IGF-1 binding

proteins as above to lower active IGF-1.

However in the Cr state, the body seems to increase the number of IGF-1

receptors, so lower IGF-1 in a Cr body may be the same functionally as

higher

IGF-1 in a non Cr body.

Yes.

It causes GROWTH.
