Well TallMan all I can find are references to support your position so I may stand corrected.
IGF-1 Elevates Blood Sugar
Insulin-like growth factor 1 also affects body composition. An anabolic hormone, IGF-1 stimulates muscle growth in laboratory animals. A July 2011 article in "Endocrinology" showed that injecting mice with IGF-1 increased their body size and muscle mass. The authors observed no evidence of IGF-1 toxicity in this report, but other studies have shown that the hormone causes unwanted side effects. A clinical trial offered in the 2007 volume of the "Journal of Clinical Endocrinology and Metabolism" tested the effects of replacement therapy with IGF-1 in children. Participants received twice daily doses of the hormone for several years. About half the kids experienced brief episodes of hypoglycemia. This elevation in blood sugar caused seizures in a few cases.
Even this vague reference contradicts itself.
However anyone who has taken IGF knows its 'insulin like' and promotes hypoglycemia, and thats where it gets a bit foggy for me, sure if we use L3 it lasts much longer but the bodies IGF is still going to have a similar action in a shorter amount of time.
Guess Im just having trouble bridging the gap on the logic there, but it sounds like you were right.
Heres another thats a bit more to the point:
Growth hormone is actually called a "counter-regulatory hormone' to insulin. It decreases the effect insulin has on the cells in that the ability of the cells to take in glucose is diminished. So this means that your BLOOD sugar will be increased.
Also GH stops the glucose synthesis in the liver.
What can I say even an old dog can learn a new trick.
