Longevity curious
The "live better, longer" peptides — big ideas, early evidence, lots of marketing
How strong is the science here?
There are some human studies, but they tend to be small, mixed, or early — not enough to be sure.
Probably not your path if…
- Anyone expecting proven life-extension in humans
- Treating longevity marketing as settled science
- Skipping the basics (sleep, food, movement) for a vial
Compounds to explore
- Some human data
NAD+
NAD+ is a core energy molecule in every cell. IV NAD is trendy; evidence for big wellness claims is mixed.
- Some human data
Epithalon
A short peptide (also called Epitalon) famous in longevity circles for telomeres and aging.
- Clinical evidence
SS-31
A mitochondria-targeting peptide (elamipretide) tested in serious medical trials.
Who this is for
You're interested in aging well and keep seeing longevity peptides. You want the grounded version — what's promising versus what's mostly marketing.
How to think about it
This is the most speculative corner of the site, so calibrate your expectations. NAD is central to how cells make energy and is popular in clinics, though the outcome data for infusions is mixed. Epithalon has an interesting aging-and-sleep research story, mostly from Russian labs. SS-31 (elamipretide) targets the mitochondria — the cell's power plants — and is the furthest along in real clinical trials. None of it is proven to extend human lifespan.
