Any specific variant of MOND, with definite formulae for the gravitational quantities, is falsifiable. (Though it may not be very easy to verify or falsify it, because besides the hypothetical "dark matter" there also exists true dark matter, i.e. interstellar gas and dust clouds.) Any theory based on dark matter is not falsifiable, regardless what model is used for gravitation, because for now there is no constraint on the distribution of the dark matter. The only way for the theory of dark matter to become a scientific theory is to discover an alternative way to determine where the dark matter is located, besides placing it wherever necessary to remove the discrepancies between the observations of the movements of the celestial bodies and the predictions of the current model of gravitation.
