Adrenomedullin vs Angiotensin 1-9

Adrenomedullin vs Angiotensin 1-9 — 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...

Angiotensin 1-9
Cardiovascular Peptide

Angiotensin 1-9 (Ang 1-9) is a 9-amino acid peptide formed when ACE2 cleaves the C-terminal leucine from angiotensin I (Ang I, 10 AA). Discovered as part of the counter-regulatory renin-angiotensin system (RAS), Ang 1-9 opposes the hypertensive and tissue-damaging actions of angi...
