igf-1

IGF -1 is the only test that can be ran to determine your Growth Hormone level.

My Dr tests everything for me and each time my Growth Level is HIGH.

IGF is insulin growth hormone factor, the only booed test that tells your Growth Hormone levels.

If low I could get from my Dr but of course they charge more than you and I like doing business with you, for a couple of years now we have had a great relationship. So I know the Kefei is really good :)
