Ostarine from SarmsX is the real thing and it will HELP keep your gainzzzz, but only diet and regular workouts for maintaining your gainzz will get you to keep them!
Also IMO, Ostarine should be used with GW 501516-Cardarine to help keep fat off and energie up as long as your diet and rxcersise plan are in line! I use both ftom SarmsX. Your good to go dude.
