Resveratrol and other things to avoid

I have looked into the contents of the products used by bodybuilding men to effectively lower estrogen and thereby avoid gyne. It give a bit of a clue on what to avoid if you wish to grow breasts on a biologically male body.
The most common ingredients:
Tribulus Terrestris (testosterone booster)
Zinc (known to lower estrogen levels in the body while promoting testosterone)
Avena Sativa (releases bound testosterone in the blood)
Calcium D-glucarate (lowers estrogen levels)
Vitex Agnus-Castus (lowers estrogen and prolactine levels while raising testosterone)
3,5,4-Trihydroxystilbene (estrogen antagonist)
Products that are said to help AGAINST gyne also often contain citrus and green tea.
Calcium D-glucarate is the calcium salt of D-glucaric acid, a natural substance found in many fruits and vegetables. Foods high in glucaric acid (a form of calcium D-glucarate) include grapefruit, apples, oranges, brussels sprouts, broccoli, cabbage, and bean sprouts. Calcium D-glucarate clears excess estrogen from the body by inhibiting the enzyme that's responsible for the activation of bound estrogen, so we can say that it is a powerful estrogen eliminator. Large doses of Calcium-D-Glucarate have been shown to lower serum estrogen levels in rats by 23 percent. But it also works against hormone related cancer so it's not all bad...

The phytoalexin resveratrol is found in grapes. Some people think this has an estrogenic effect on the body. Although it is indeed a phytochemical, and appears to be estrogenic, it can actually work as an estrogen blocker. Resveratrol has another name too - 3,5,4-Trihydroxystilbene. Trihydroxystilbene blocks estrogen at the actual receptor site in male breast tissue and other estrogen-sensitive tissues. 3,5,4-Trihydroxystilbene is an effective inhibitor of aromatase as well as an antagonist of the estrogen receptor. This greatly reduces the amount of estrogen activity and results in higher natural levels of testosterone. This is why it is used in products that bodybuilders use to avoid "bitchtits".
Endogenous estrogens are steroid hormones synthesized by humans and other mammals that bind to estrogen receptors within cells. A compound that binds to estrogen receptors and elicits similar responses to endogenous estrogens is considered an estrogen agonist, while a compound that binds estrogen receptors but prevents or inhibits the response elicited by endogenous estrogens is considered an estrogen antagonist.
In cell culture experiments, resveratrol acts as an estrogen agonist in the absence of 17-beta-estradiol, but acted as an estrogen antagonist in the presence of 17-beta-estradiol. It appears that Resveratrol has the potential to act as an estrogen agonist or antagonist depending on such factors as cell type, estrogen receptor isoform (ER alpha or ER beta), and the presence of endogenous estrogens. If there is estrogen present, it acts as an antagonist, reducing estrogen activity. So for anyone who naturally has, or is adding estrogen to their system, Resveratrol will reduce it's effects.
