Best Peptide for Anti-Aging
Anti-aging peptides target aging at the source — telomere shortening, mitochondrial decline, gene expression drift, and GH axis attenuation. This guide compares the top four compounds with clinical evidence, dosing, and a decision framework.

Frequently Asked Questions
Which anti-aging peptide has the most evidence?
Epithalon has the most long-term human evidence for actual longevity outcomes — the Khavinson Institute published 15-year follow-up data showing 27–36% reductions in all-cause mortality. GHK-Cu has the most robust mechanistic data, with over 4,000 studies documenting its gene expression effects. NAD+ (via NMN/NR) has the strongest understanding of mechanism and the most rapidly growing human trial database. For pure evidence-of-longevity, Epithalon's human mortality data is unique in the peptide world.
Can I take all three together?
Yes — and this is the recommended approach for comprehensive anti-aging. The Longevity Elite Stack combines Epithalon, GHK-Cu, NAD+, and CJC-1295/Ipamorelin because they operate through entirely different pathways with no negative interactions. Epithalon handles telomere biology, GHK-Cu resets gene expression and tissue regeneration, NAD+ restores mitochondrial function, and the GH stack optimizes hormonal anti-aging. They are additive at minimum, potentially synergistic.
How often do I run Epithalon?
Epithalon is run in short cycles rather than continuously. The standard protocol is 5–10mg per day for 10–20 consecutive days, repeated 1–2 times per year. The Khavinson research used 5mg/day for 10 days, twice yearly. Unlike most peptides, Epithalon's telomere effects persist long after the cycle ends — you are triggering telomerase expression, not relying on a constant blood level. Many users do a spring and autumn cycle annually.
What's the difference between anti-aging and longevity?
Anti-aging typically refers to visible and functional markers: skin quality, body composition, energy, cognitive sharpness, and joint health — things that are measurable in months. Longevity refers to extending lifespan and healthspan at the cellular level — telomere preservation, mitochondrial function, sirtuin activation, and reduced all-cause mortality. The best approach addresses both: GHK-Cu and GH peptides drive anti-aging aesthetics and function, while Epithalon and NAD+ target the fundamental longevity biology. The Longevity Elite Stack covers both layers.
