Best Peptides for Anti-Aging

Epitalon (Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the natural pineal gland peptide epithalamin, developed by Russian gerontologist Professor Vladimir Khavinson over three decades of research. It is the most extensively studied telomerase-activating peptide, shown to lengthen telomeres, restore melatonin production, and extend lifespan in multiple animal models. Epitalon occupies a unique position in anti-aging research as one of the few compounds with direct evidence of telomere elongation in human cell cultures.

FOXO4-DRI is a D-retro-inverso peptide that selectively induces apoptosis in senescent cells — making it a true senolytic agent. Developed by Peter de Keizer at Erasmus University Medical Center, it works by disrupting the interaction between FOXO4 and p53 that keeps senescent cells alive. In aged mice, it restored fitness, fur density, and renal function.

MOTS-c (Mitochondrial Open Reading Frame of the 12S rRNA Type-c) is a mitochondrial-derived peptide that functions as a systemic exercise mimetic and metabolic regulator. Discovered in 2015 by Dr. Changhan David Lee's lab at USC, it is the first peptide shown to be encoded in the mitochondrial genome yet act on the nuclear genome, fundamentally challenging the traditional view of mitochondria as passive energy producers. MOTS-c activates AMPK, regulates metabolic homeostasis, and has demonstrated remarkable anti-aging and exercise-mimetic effects in both preclinical and early human studies.

N-Acetyl Epitalon is a modified form of Epitalon (epithalon), a synthetic tetrapeptide (Ala-Glu-Asp-Gly) that activates telomerase and is studied for anti-aging properties. The N-acetyl modification enhances its bioavailability and resistance to enzymatic degradation compared to standard Epitalon. It was originally developed based on the work of Dr. Vladimir Khavinson on pineal gland peptide bioregulators.

NAD+ (nicotinamide adenine dinucleotide) is a critical coenzyme found in every living cell that plays essential roles in energy metabolism, DNA repair, gene expression regulation, and cellular signaling. NAD+ levels decline significantly with age — by age 60, levels are roughly half of what they were at age 20 — and this decline is implicated in numerous age-related diseases. Supplementation via IV infusion, subcutaneous injection, or precursors aims to restore youthful NAD+ levels and support cellular function.

PNC-27 is a synthetic anticancer peptide consisting of an HDM-2 (MDM2) binding domain fused to a cell-penetrating peptide leader sequence. It selectively targets and kills cancer cells that overexpress HDM-2 on their surface while sparing normal cells. It represents a targeted approach to cancer-cell destruction based on exploiting the differential expression of MDM2 between cancerous and healthy tissue.

SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of expression wrinkles by modulating neuromuscular junction signaling. It is a longer, more potent version of Argireline (Acetyl Hexapeptide-3) and works by partially inhibiting the SNARE complex responsible for vesicular neurotransmitter release. Often called 'topical Botox,' it offers a non-invasive approach to wrinkle reduction.

SS-31 (Elamipretide, Bendavia, MTP-131) is a mitochondria-targeted tetrapeptide that selectively concentrates in the inner mitochondrial membrane and restores bioenergetic function. It binds to cardiolipin, a phospholipid unique to mitochondria that is essential for electron transport chain efficiency. SS-31 represents a first-in-class approach to treating mitochondrial dysfunction, with clinical trials in heart failure, Barth syndrome, and age-related mitochondrial decline.
