We investigate the precessing motion around the the regular black hole with an asymptotically Minkowski core which has a suppression parameter . We obtain the third-order post-Newtonian quasi-Keplerian motion of a test particle in this spacetime and find its relativistic periastron advance. Then, we test this model with the precessing motion of the star S2 and of OJ 287 and determine the upper limits of the dimensionless suppression parameter as , where m is the mass of the black hole. Compared with the bound given by the shadow of Sgr A*, our bound on is reduced by 2 orders of magnitude, although our upper limit of still needs further improvement.
