Adrenomedullin vs Urocortin

Adrenomedullin vs Urocortin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Adrenomedullin
Cardiovascular Peptide

Adrenomedullin (ADM) is a 52-amino acid vasoactive peptide first isolated from human pheochromocytoma tissue in 1993. It is now recognized as a pleiotropic hormone produced widely throughout the body, with highest expression in the adrenal medulla, heart, lung, kidney, and vascul...

Urocortin
Cardiovascular Peptide

Urocortin 1 (UCN1) is a 40-amino acid peptide belonging to the corticotropin-releasing factor (CRF) family. While sharing structural homology with CRF, UCN1 binds with higher affinity to CRF receptor type 2 (CRFR2), which predominates in the heart, skeletal muscle, and peripheral...
