GH7 or KH3 are just names trying to copy the genuine GH3 Gerovital even they dont contain the original formula by Ana Aslan but a fantasy Gingko Biloba formula with only PLACEBO effects !!! I QUOTE from WIKIPEDIA : ''The drugs existing on the market today are made after the original medicine but are not directly related to Ana Aslan's medicine. They are only using the fame of the original name. Especially the ones produced outside Romania.'' I use only the genuine gerovital produced in Romania by the original manufacturer since Ana Aslan's dicovery of its formula .
