Research Overview
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
Epoetin Alfa
Human studies in anemia and performance-related settings show that increasing red-cell mass can improve aerobic capacity and endurance. It remains heavily regulated because excessive erythropoiesis raises thrombotic and cardiovascular risk.
