The differences that actually matter
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Once reconstituted, SS-31 (Elamipretide) keeps noticeably longer than Epithalon (~30 days vs ~21 days), so vial waste is a real difference between the two.
Reported mainly for Epithalon: better sleep, melatonin restoration, longevity markers.
Reported mainly for SS-31 (Elamipretide): mitochondrial repair, energy, cardiovascular support.
What Epithalon is
Epithalon is a synthetic tetrapeptide, Ala-Glu-Asp-Gly, that is understood to influence gene expression. Its primary researched mechanism involves the upregulation of telomerase activity, an enzyme crucial for maintaining the length and integrity of telomeres, which are protective caps on chromosomes. While it does not typically target specific receptors in the conventional sense, Epithalon is thought to modulate regulatory pathways, particularly within the pineal gland, impacting the synthesis of melatonin and ant
What SS-31 (Elamipretide) is
SS-31, also known as Elamipretide, is a small, aromatic-cationic peptide designed to selectively target mitochondria. It primarily localizes to the inner mitochondrial membrane where it interacts with cardiolipin, a unique phospholipid essential for mitochondrial structure and bioenergetics. By binding to cardiolipin, SS-31 helps to stabilize the inner mitochondrial membrane, protect it from oxidative damage, and preserve the integrity of the electron transport chain. This action supports efficient ATP production a
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Epithalon and SS-31 (Elamipretide) are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Epithalon and SS-31 (Elamipretide)?
Both are classed as Longevity peptides, so they get compared constantly and are often researched for overlapping reasons.
Can you log Epithalon and SS-31 (Elamipretide) in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Epithalon or SS-31 (Elamipretide)?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
