His power is to mess with hormones. So in theory he could work similar to Shelong unlocking people's potential. He could make one more muscular, bigger, smarter etc. Maybe even unlocking haki and making it stronger.
He definitely can make people stronger with it. Imagine an awakening of his DF. He can maybe even shit his awakening to it with his DF basic powers. And make others to awaken as well. He definitely shouldn't have lost to Magellan.
