As a good friend of mine reminded me the saying was (and you said it while you did the exercise)
You must, you must, you must increase your bust, the bigger the better the tighter the sweater you must increase your bust!
(still laughing Michele!) hahahahahahhahahhahah
If I remember properly, which we all know I don't, I think it worked on my biceps and not pecs so much.... yah, still had 38 longs!
I remember a device thingy back when I was a teenager and dinosaurs roamed the earth... can't remember the name of it but you held it directly in front of your breasts and used both arms to squeeze it, supposedly to make them grow larger. >>>>>>>Mark EDEN bust enhancer!!! Hahahahahhahahahaha (didn't work but breast cancer took the boobs and a micro surgeon recreated them)
Ok, so was this a serious question? Don't waste your money on that junk... really :)
I think it would be risky to try this product, which is advertised as an herbal product, because such products are unregulated. They might contain no "active ingredient," a huge amount to plant estrogens, or even be illegally spiked with prescription estrogens. So yes, they could be problematic.
Another question to consider would be, "Does it work?" (Do you really believe millions of women would spend thousands of dollars and put themselves through breast augmentation surgery, if a bag of herbs would do the trick?)
A third issue is can you trust their money-back guarantee? (Apparently not, according to one post on Ripoff Report, a consumer Web site.
