Best Peptides for Anti-Aging & Longevity
The peptides most studied for anti-aging and longevity include Epithalon (researched for telomerase and circadian pathways), NAD+ and SS-31 for mitochondrial function, MOTS-c for metabolic aging, and Thymalin for immune aging. Most evidence is preclinical.
Longevity peptides target the biology of aging rather than a single symptom. Epithalon is the most-discussed, studied for telomerase activity and circadian/pineal regulation. A mitochondrial group — NAD+, SS-31, MOTS-c, Humanin — is researched for cellular energy and metabolic aging. Thymalin and related thymic peptides are studied for immune aging. This is among the most preliminary categories: most data is animal or in-vitro, graded below.

Frequently asked questions
- Do anti-aging peptides actually extend lifespan?
- No human peptide has been shown to extend human lifespan. Compounds like Epithalon show longevity signals in animal studies, but this does not translate to proven human anti-aging benefit. Treat this category as experimental.
- Are these peptides legal and FDA-approved?
- Most research peptides discussed here are not FDA-approved for human use and are sold strictly for laboratory research purposes. A few molecules (such as certain GLP-1 receptor agonists) exist in approved prescription forms, but the research-grade material referenced on this site is not the same as a prescription product. Always consult a licensed healthcare provider before making any health decision.
- How strong is the research behind these?
- It varies by compound. Some — like the GLP-1 agonists — have large human clinical trials; others (such as BPC-157 or Epithalon) rest mainly on animal and in-vitro data with limited human studies. Each protocol page on this site grades the evidence so you can see exactly what is well-supported versus preliminary.
