I don't see why the moon rocks should be a fake. The Russians and the Americans were certainly not best friends at the time and both sides presented rock to the scientific community which was compared to ateroid and meteor remains to ascertain differences to these and earth rock. Both the American and Russian rock was identical so either they worked together to fake the whole thing or they independently through luck produced exactly the same type of synthetic rock or it came from the moon. I will let you decide on that one.
