I train tennis, swimming and also do workouts at home. is it clever and safe to consume proteins (such as whey or similar) to get more muscles and mas?

Teen Boys: I am always amazed at the young men who ask this question. They are in the prime of their life and their bodies are usually perfect. So, i would say this is not 'clever'. But it is safe if you must try to grow 'bigger' muscles than nature intends. But, a 17 year old healthy young man often just needs to keep eating good food high in protein.
