Peptides, senolytics & the experiments

Frontier

The most interesting corner of the field, and the one where the gap between excitement and evidence is widest. Plausible mechanisms, striking animal data, thin human proof. We take it seriously enough to explain it properly — and seriously enough to tell you when there's no human trial behind the hype.

Frontier

Urolithin A

A gut-microbiome metabolite that improves mitochondrial quality — with a few real human RCTs showing modest muscle and endurance effects.

C Suggestive evidence Know the context

Frontier

NMN & NR

NAD+ precursors that reliably raise a biomarker — with almost no evidence yet that the biomarker translates to living longer or better.

C Suggestive evidence Know the context

Frontier

Rapamycin

The strongest animal-longevity signal in the field — and almost no human outcome data. A fascinating hypothesis, not a protocol.

D Mechanistic evidence Know the context

Frontier

Spermidine

A dietary polyamine tied to autophagy and, in observational data, to longer life — with human trials still small and early.

C Suggestive evidence Know the context

Frontier

Resveratrol

The red-wine 'longevity molecule' that launched a thousand supplements and then failed to deliver in humans.

D Mechanistic evidence Skip it

Frontier

BPC-157

A 'healing peptide' with genuinely interesting animal data and essentially no human trials, sold gray-market with unknown safety.

D Mechanistic evidence Know the context

Frontier

GH secretagogues

Sermorelin, ipamorelin and similar peptides that nudge growth-hormone release — marketed for anti-aging on evidence that doesn't exist.

D Mechanistic evidence Know the context

Frontier

Senolytics

Drugs that try to clear 'zombie' senescent cells — one of the most promising longevity ideas, and nowhere near ready to self-administer.
