There are several supplements that are available in the market and I don't know how safe they are. You can consult your gym instructor and make sure that you get a good one. If you don't trust your gym instructor then you can ask your friends and check if they are have used supplements before. Generally, most protein supplements are safe as long as you burn energy. If you take supplements then you must hit the gym and get rid of all that excess protein. Both cardio and muscle building exercises are extremely important. Hope that was what you are looking for.
