Cortisol triggered by stress will prevent breast growth reaching full potential, except in older men with big bellys (which will release prolactin, then boom, gynecomatsia happens, and similar tubular breasts growth occurs). Depression, being overweight is another breast buster. Hormones are not balanced, out of harmony and not one with the universe, (too cheesy?, lol).
I'm talking about building collagen, take a look at these websites, (just for informational purposes).
Collagen is found in skin and connective tissue (ie tendons and ligaments). Taking collagen supplements can help to tighten skin and connective tissue. The tightened skin and connective tissue can be beneficial to breasts as it can help to firm up breasts as well as lift them. Collagen also improves circulation which can be beneficial to breast growth as more oxygen and nutrients get delivered to breast cells. - See more at:

Amino Acids
According to Dr. Howard Murad, a board certified dermatologist and clinical professor of dermatology at the University of California at Los Angeles, collagen production within the body's connective tissue depends on adequate levels of amino acids. There are nine essential amino acids, which can't be manufactured by the body itself and must be obtained through diet. Generally, animal sources such as poultry, fish, cheese, milk, and eggs provide all nine amino acids.
