This is from another forum, I dunno if its true or not but yea.
Q: I have man-boobs. Not gyno from steroids or related to puberty, just a lot of fat storage on my chest. It seems to stay there when I cut down, too. Anything I can do non-surgically? What does this say about my hormone profile?
A: Most of the time, just about every time in fact, it's a sign of a zinc deficiency. Zinc is the best anti-aromatase.
How many people eat a lot of organic nuts? How many people eat unrefined grains? How many people eat quality grass-fed meat? Scallops and oysters? Just about everyone is zinc deficient, especially people who lift weights.
Low zinc means increased aromatase activity, and that means man-boobs. In the last ten years, I haven't seen a single male first-time client who wasn't zinc deficient.
Other things that have natural anti-aromatase activity would be grape seed extract, resveratrol (REZ-V), and DIM. You should also look to pull out xenoestrogens with calcium D-glucarate. It's not a source of calcium; it's a source of D-glucarate, and that pulls out foreign estrogens.
