Epitalon vs NMN
The honest difference
NMN has small human studies, while Epitalon rests mostly on lab and animal work. Neither has been shown to slow ageing in people.
Peptide
Epitalon
Grade D: animal data only
Why people buy it
People buy it to slow ageing and live longer. Some also take it for better sleep.
Bottom line
Interesting in lab dishes and mice, unproven in people. The big anti-ageing claims are not backed up.
- UK status
- Not a licensed medicine in the UK and not approved by the MHRA for any use.
- Sport / WADA
- Not specifically listed by name on the WADA Prohibited List.
Peptide
NMN
Grade C: early / limited human data
Why people buy it
People take it as a supplement pill to slow ageing and live longer. The body turns it into NAD+, a molecule cells use for energy.
Bottom line
It raises a number in your blood. Whether that slows ageing in people is still unknown.
- UK status
- NMN is not a licensed medicine in the UK. Its supplement status hinges on novel food rules: NMN was not widely eaten before 15 May 1997, so it is treated as a 'novel food' requiring Food Standards Agency authorisation before legal sale as a food supplement.
- Sport / WADA
- NMN is not specifically named on the WADA Prohibited List as of 2026.
Grades are about evidence in humans, not about whether something is right for you. Nothing here is dosing advice. Talk to a qualified clinician before any health decision.
