In this work, we investigate the dynamics of test particles in the background of the Bocharova-Bronnikov-Melnikov-Bekenstein (BBMB) black hole solution, which arises in a scalar-tensor theory with a conformally coupled scalar field. We analyze the motion of neutral particles by deriving the effective potential governing geodesic motion in the BBMB spacetime. The influence of the conformal scalar field on the energy and angular momentum of test particles is studied in detail, with particular emphasis on the stability of circular orbits and the determination of the innermost stable circular orbit (ISCO). Our results reveal that the scalar field significantly modifies the geodesic structure near the black hole horizon, leading to shifts in the location and energy of the ISCO compared to the Schwarzschild case. These deviations may have implications for accretion disk physics and observable signatures around black holes with scalar hair. The study highlights the role of scalar fields in altering particle trajectories and provides further insights into alternative gravity scenarios.
