Epithalon vs SS-31
Which should you choose? Here's what you need to know.
The short answer
Epithalon protects cells from aging by maintaining telomeres. SS-31 protects mitochondria from aging by stabilizing their inner membrane. Both are anti-aging but at different cellular targets.
On 9 Oct 2026 Peptide Compare tracked 57 vendors selling Epithalon, cheapest in stock $1.30 per mg at Nextech Labs, and 29 selling SS-31, cheapest $2.30 per mg at Nextech Labs.
Epithalon

Choose Epithalon if:
You're focused on telomere-level longevity and chromosomal protection.
SS-31
Metabolic / LongevitySS-31 (elamipretide) is an FDA-approved synthetic peptide that physically stabilizes the inner mitochondrial membrane, protecting energy production and reducing oxidative damage.
Choose SS-31 if:
You want to directly protect and restore mitochondrial function, especially for age-related energy decline.
