Dimension Breakdown
DimensionScoring NotesScore
Study Design
Primarily in vitro and mouse/rat models for Alzheimer's, cardiovascular protection, and metabolic function. Some human correlational data (endogenous levels) but no intervention RCTs in humans.
2 / 25
Sample Size
No human intervention participants. In vitro and animal studies only for interventional evidence.
0 / 20
Replication
In vitro neuroprotective findings and animal studies replicated across multiple independent groups globally. Mitochondria-derived peptide field has active academic interest.
15 / 20
Journal Impact Factor
Published in PNAS (IF ~11), Nature Aging, Cell Metabolism. Parent mitochondria-derived peptide research has strong journal placement.
8 / 15
Funding Independence
NIH and academic funded. Independent research — Pinchas Cohen (USC) and others have NIH-backed programs.
7 / 10
Population Diversity
Animal/in vitro only. Not applicable.
3 / 5
Researcher h-Index
Pinchas Cohen (USC Dean of Gerontology) has h-Index 60+. The defining humanin researcher has a very strong profile. Capped at 5.
2 / 5
Animal Only Note
This score reflects evidence in humans. Animal and in vitro evidence may be substantially stronger than the score suggests — this compound has not yet been studied in human trials.
