It doesn't have anything to do with real IGF-1. It is octacosanol. Octacosanol is a sugar alcohol made from sugar cane wax. Its also present in wheat germ oil. It interfears with cholesterol synthesis which might be good if you have a problem with cholesterol, but it will do nothing for muscle growth. In fact, it might actually hamper it slightly if it interferes with the muscle's ability to produce cholesterol for cellular repair.
There is no medical research to back up their claims. Using wheat germ oil as a "tonic" is as old as the hills but it has no effect whatsoever on muscle growth.
Furhtermore, a thorough analysis of studies has not supported the claim that wheat germ oil is an effective performance aid. This evidence was used successfully by the Federal Trade Commission to ban advertising claims that wheat germ could improve endurance, strength, and vigor. So this company simply changed the name they were calling it and said it will grow muscles.
They should be ashamed for making false claims and deceptive advertising.
