Epithalon and Humanin are both Longevity peptides, but they're studied for different things. In short, Epithalon is a tetrapeptide studied for telomerase activity and aging, while Humanin is a mitochondrial-derived peptide studied for cytoprotection and aging. This page compares the two side by side — what each is researched for, how mature the evidence is, and how they're typically used — so you can see where they overlap and where they differ. It's educational information only, not medical advice, and neither is a substitute for a conversation with a licensed professional.

How does Epithalon work?
Epithalon (epitalon) is a synthetic tetrapeptide based on the pineal extract epithalamin. It is studied in the longevity field for possible effects on telomerase activity and on circadian and hormonal regulation, primarily in animal and limited human research.
How does Humanin work?
Humanin is a mitochondrial-derived peptide with cytoprotective properties. Research has explored roles in metabolism, neuroprotection, and age-related conditions, making it a subject of interest in longevity science.
Epithalon vs Humanin: how to choose
Choosing between Epithalon and Humanin really comes down to your specific goal — and it's a decision for you and a licensed professional, not something to settle from a web page. Epithalon is most associated with Telomere & aging research and Sleep & circadian rhythm, while Humanin leans toward Cytoprotection and Metabolic health. Where they overlap, the practical differences are usually in mechanism and how far the research has actually progressed.

Frequently asked questions
Both are Longevity peptides. Epithalon is a tetrapeptide studied for telomerase activity and aging; Humanin is a mitochondrial-derived peptide studied for cytoprotection and aging. They're most researched for Telomere & aging research, Sleep & circadian rhythm (Epithalon) and Cytoprotection, Metabolic health (Humanin), respectively.
There's no universal "better" — it depends on your goal, and for most of these compounds robust head-to-head human evidence doesn't exist. The right choice is one made with a licensed professional. Selpho does not rank or prescribe; it offers educational information and a research-backed advisor.
They're in the same category, and combining research compounds is something to approach only with a licensed professional, since interactions and individual context matter. Selpho provides no dosing or protocols.
Epithalon: Limited human data, largely from Russian longevity research. Humanin: Preclinical research; emerging human interest.
