bigger breasts
There seems to be three types of breast enhancement product on the market right now:
herbal based phytoestrogens (i.e. Newbust, Grobust)
grain based phytoestrogens (i.e. Isis, Miracle Breast)
bovine ovary concentrate (Wonderbreast, Ova-lyte)
Some of them work for SOME women. Not all women have the same response and it seems to depend on their bodyfat percentage, whether they've ever been pregnant, etc. A lot of different factors.
Birth control pills can cause some growth, but it's just as likely it will end up on the butt too. Same with other synthetic hormones (HRT, estridiol, etc.).
I've been using about 1800-2400 mgs of bovine ovary concentrate and have been very happy with the results - about an inch in 6 weeks - and will continue taking them. Wonderbreast is bloody expensive, so I am using another brand. An internet seach on "bovine ovary concentrate" should yield the names of several manufacturers that will fit the budget. Ova-Lyte is a popular brand.
Failing that, there IS surgery, but you might as well try a less invasive method first. Not all women respond to all of these products, and it does take some months to see any real results. Depends really on your patience, your pocketbook, and the amount of cleavage you want vs. the risks of surgery.
