Best Peptides for Anti-Aging
Anti-aging peptides target the fundamental mechanisms of biological aging — telomere shortening, mitochondrial decline, cellular senescence, and oxidative stress. From copper peptides that remodel skin to senolytics that clear zombie cells, this category spans the frontier of longevity science.

Showing 19 peptides ranked by popularity and research evidence
NAD+
ResearchAnti-AgingA coenzyme present in every living cell, critical for energy metabolism and cellular repair. NAD+ levels decline with age; replenishment is a cornerstone of modern longevity medicine.
Sermorelin
ResearchGrowth HormoneA bioidentical analog of growth hormone-releasing hormone (GHRH). The bedrock of clinical anti-aging endocrinology, prescribed to safely restore youthful IGF-1 levels and improve sleep.
Ipamorelin
ResearchGrowth HormoneThe cleanest growth hormone secretagogue available, delivering potent GH pulses without triggering hunger, cortisol, or prolactin spikes. The premier choice for year-round anti-aging protocols.
GHK-Cu
ResearchAnti-AgingA naturally occurring copper-binding tripeptide that modulates over 4,000 human genes. The gold standard in dermal remodeling, wound healing, and systemic anti-aging research.
CJC-1295
ResearchGrowth HormoneA modified GHRH analog that delivers intense, acute GH spikes mimicking natural nocturnal pulses. Almost always stacked with Ipamorelin for synergistic, non-suppressive GH release.
Epitalon
ResearchAnti-AgingA synthetic tetrapeptide derived from the bovine pineal gland, sitting at the apex of life-extension bioscience. Studied for its ability to activate telomerase and reset the biological clock.
KPV
ResearchRecoveryA master anti-inflammatory tripeptide derived from alpha-MSH. Obliterates systemic inflammation at the genetic level without immunosuppression, making it a staple for IBD and gut health.
MOTS-c
ResearchMitochondrialA mitochondrial-derived peptide dubbed an 'exercise mimetic' that reverses age-related insulin resistance and enhances fat oxidation even in sedentary individuals.
SS-31
Clinical TrialsMitochondrialA mitochondria-targeted tetrapeptide that stabilizes the inner membrane to halt age-related energy decline. In clinical trials for heart failure and rare mitochondrial diseases.
Glutathione
ResearchAnti-AgingThe body's master antioxidant — an endogenous tripeptide critical for liver detoxification and cellular defense. Levels decline with age and toxin exposure.
FOXO4-DRI
ResearchAnti-AgingA senolytic peptide that selectively forces zombie (senescent) cells to self-destruct, reducing systemic inflammation and reversing aging markers.
Humanin
ResearchAnti-AgingA mitochondrial-derived peptide that protects against programmed cell death. Discovered in brains of Alzheimer's patients who resisted neural decay.
Matrixyl
ResearchCosmeticThe gold standard in structural dermal remodeling. Tricks the skin into overproducing collagen by mimicking wound signals.
Thymalin
ResearchAnti-AgingA legendary polypeptide bioregulator from Soviet military research that regenerates the involuted thymus gland and extends lifespan.
SLU-PP-332
ResearchMitochondrialA synthetic ERRγ agonist hailed as an exercise mimetic that replicates endurance training adaptations without physical exertion.
Sermorelin + Ipamorelin
ResearchGrowth HormoneThe 'Golden Ratio' of clinical anti-aging: a GHRH + GHRP combination that produces synergistic GH release exceeding either peptide alone.
Decapeptide-12
ResearchCosmeticA skin-lightening peptide that inhibits melanin production for even skin tone without the toxicity of hydroquinone.
Epithalamin
ResearchBioregulatorThe natural Cytomax extraction from pineal glands, the raw predecessor to synthetic Epitalon. Used in Khavinson's landmark 15-year human longevity studies.
Endoluten
ResearchBioregulatorThe crown jewel of the Khavinson Cytomax line — the natural pineal extract predecessor to Epitalon for circadian and longevity restoration.
