the blue tops that i am not using have none of the redness but all other signs of gh sides. however, many say that because it's not known if the china gh is 191 or 192aa that it can either:
1) a reaction to the 192aa
2) a reaction to the filler since its uknown how pure the gh is
also, many people were getting red whelts from the water that was provided with certain kits however were not getting the same reaction once changing to bac water.
