Epithalon vs MOTS-c
Epithalon and MOTS-c are both grouped under longevity research, but they come from entirely different biological contexts. This page sets out how they differ so a protocol can be matched to the right compound.
Different origins
Epithalon is a synthetic tetrapeptide developed from work on pineal peptide preparations and is usually discussed alongside other bioregulator peptides. MOTS-c is a mitochondrial-derived peptide, encoded in mitochondrial DNA rather than assembled as a fragment of a larger nuclear-encoded protein. That difference in origin drives the difference in research literature.
Research context
Epithalon appears mainly in ageing and bioregulator research. MOTS-c is studied predominantly in metabolic and mitochondrial research. Both bodies of work are preclinical in the contexts most often cited, and neither supports statements about outcomes in people.
Analytical documentation
The two compounds differ substantially in sequence length, so their expected masses and chromatographic behaviour are distinct. Each lot of each compound is analysed independently by reversed-phase HPLC for purity and mass spectrometry for identity, and released with a lot-matched certificate.
Scope
This comparison describes published research characterisation only. It contains no efficacy claim, no superiority claim and no dosing or administration guidance. Both compounds are supplied for laboratory research only.
