• Angiotensinogenum → angiotensini I
• Cholecalciferolum (Vitaminum D₃) → calcitrioli
• Dehydroepiandrosteronum → androgenorum et oestrogenorum
• Procalcitoninum → calcitonini
• Proglucagon → glucagoni
• Prohormon N-terminus peptidi natriuretici cerebralis (Nt-ProBNP)^[1]
• Proinsulinum → insulini
• Thyroxinum (T₄) → triiodthyronini (T₃)

Prohormonta supplementum nutriminum

Quaedam prohormonum, imprimis talia testosteroni supplementum nutrimium, consumantur^[2]. In artibus athleticis consumptio prohormonum adulescentibus vel in pueritia dubitabilissime videtur^[3].
