KPV vs Adrenomedullin
Side-by-Side Comparison
| Attribute | Kpv | Adrenomedullin |
|---|---|---|
| Category | Anti-Inflammatory / Immune | Cardiovascular / Vasoactive |
| Mechanism | KPV exerts anti-inflammatory effects through a mechanism distinct from the parent α-MSH hormone. Rather than acting through melanocortin receptors (which would trigger pigmentation), KPV is... | Adrenomedullin signals through the calcitonin receptor-like receptor (CLR) complexed with receptor activity-modifying protein 2 or 3 (RAMP2/RAMP3), forming the AM1 and AM2 receptors respectively. |
| Evidence Rating | D — Preclinical | D — Biomarker / Early Research |
| Clinical Status | Preclinical. No formal clinical trials completed. Used in compounding pharmacy protocols. Removed from FDA Category 2 on April 15, 2026. | Research stage. MR-proADM used as prognostic biomarker in sepsis and heart failure. No approved therapeutic use of adrenomedullin peptide. |
| Safety Profile | No significant adverse effects reported in preclinical studies; Does not cause skin darkening (unlike Melanotan peptides) | No human safety data from controlled therapeutic trials; Experimental IV infusion in healthy volunteers caused hypotension and reflex tachycardia |
| Route | Oral (gut), Subcutaneous (systemic), Topical (skin) | Intravenous infusion (research only) |
| Dose Range | Oral: 200-500 mcg/day; SC: 100-500 mcg/day; Topical: 0.01-0.1% preparation | 10–50 ng/kg/min in human physiological studies |
| Frequency | 1-2 times daily | Continuous or bolus infusion |
| Molecular Weight | ~342.4 g/mol | ~6028 g/mol |
| Half-Life | ~2 hours (SC); shorter oral due to GI degradation | ~22 minutes (plasma) |
Overview
KPV and Adrenomedullin are both research peptides studied across multiple applications. This comparison examines their mechanisms, evidence base, dosing protocols, and safety profiles to help researchers understand the key differences and overlaps.
KPV — Mechanism & Evidence
KPV is a naturally occurring tripeptide (Lys-Pro-Val, MW ~342.4 g/mol) derived from the C-terminal region (positions 11–13) of alpha-melanocyte-stimulating hormone (α-MSH). It retains potent anti-inflammatory and antimicrobial properties of the full-length hormone without activating melanocortin receptors responsible for skin pigmentation or sexual arousal. KPV suppresses NF-κB activation and is transported into intestinal epithelial cells via the PepT1 transporter, which is upregulated during gut inflammation — creating a self-targeting mechanism. Its small size enables oral bioavailability, which is unusual for peptides. It was among the 12 peptides removed from FDA Category 2 on April 15, 2026.
Key claims: Reduces intestinal inflammation; Anti-inflammatory without pigmentation; Wound healing and skin benefits.
Adrenomedullin — Mechanism & Evidence
Adrenomedullin is a 52-amino-acid vasodilatory peptide (MW ~6028 g/mol) originally isolated from human pheochromocytoma tissue. It is widely expressed in the cardiovascular system, lungs, kidneys, and adrenal glands, with potent vasodilatory, natriuretic, and cardioprotective properties. It is currently investigated as a biomarker (MR-proADM) for sepsis and heart failure prognosis, with no approved therapeutic use of the peptide itself.
Key claims: MR-proADM is a strong prognostic biomarker in sepsis; MR-proADM predicts mortality in acute heart failure; Adrenomedullin has potent vasodilatory effects in humans.
Shared Research Applications
These peptides target different research areas. KPV focuses on Gut Health, Immune Support, while Adrenomedullin targets Sepsis Prognostication, Heart Failure Biomarker, Cardiovascular Research.
Safety Considerations
KPV: No significant adverse effects reported in preclinical studies Does not cause skin darkening (unlike Melanotan peptides) No formal human safety trials have been conducted
Adrenomedullin: No human safety data from controlled therapeutic trials Experimental IV infusion in healthy volunteers caused hypotension and reflex tachycardia Theoretical risk of excessive vasodilation and hemodynamic instability
