For a few women: You may not know how stressful your life really is, and expect a Breast Enlargement pill to change your bust in a matter of 4 weeks. Studies have shown that most supplements will not do this.  Just like puberty didn't happen over the' course of one month, usually a breast pill will not change your cup size in a month.  It can take some women up to a full year to see a cup size increase.  Othe'r women may see larger breasts or results in a matter of 2-3 months.  Each individual will respond to the' ingredients differently based on body chemistry as well as external forces already mentioned.
