"You're familiar with HGH, correct?" asked Key, referring to human growth hormone. "It's converted in the liver to IGF-1." IGF-1, or -insulin-like growth factor, is a natural, anabolic hormone that stimulates muscle growth. "We have deer that we harvest out of New Zealand," Key said. "Their antlers are the fastest-growing substance on planet Earth . . . because of the high concentration of IGF-1. We've been able to freeze dry that out, extract it, put it in a sublingual spray that you shake for 20 seconds and then spray three [times] under your tongue. . . . This stuff has been around for almost 1,000 years, this is stuff from the Chinese."
