Are there any nootropics shown to increase intelligence?

People on the r/nootropics subreddit have mentioned Dihexa and Cerebrolysin being potential "IQ increasers". Cerebrolysin being a mixture of peptides derived from the brains of pig that are injected IM and Dihexa being a potent nuerogenesis catalyst. Some guy from longecity even claimed to have gained an eidetic memory from taking cerebrolysin, and the ability to manipulate very complicated 3D shapes in his head. However, the guy is probably larping. Dihexa seems dangerous and Cerebrolysin seems to be a risk factor for prion disease since it is derived from pig brains. Anyone have thoughts on this?
