I have been reading some postings that suggest that IGF-1 and human growth hormone in combination with estrogen will result in breast enlargement. Are there herbs, natural supplements, or types of exercise that can be used to increase IGF-1 and human growth hormone? What successes have you had with these methods of breast growth? I would like to improve my personal breast enlargement program of progesterone cream, PM, soy isoflavones,, and fenugreek seed by using natural methods to increase ICF-1 and human growth hormone that do not require the use of synthetic drugs. Many thanks to anyone who responds to this posting.
