Unfortunately, this formula favored by the Qing Dynasty Imperial family, especially Empress Dowager Ci Xi and formulated by Dr. Chang’s family has several key ingredients that are no longer available, as a result GT-715 Brain Enhancer is no longer available.  We apologize for this sad news, however, one may pray that things change.  If this does change in the future, then we will provide an update here and on the QiInstitute.com store/site.

Many Blessings to all of you!
