Best Peptides for Anti-Aging & Longevity
GHK-Cu, epithalon, SS-31 and more — ranked on longevity evidence from clinical to preclinical.
Anti-aging peptides are best understood as targeted tools: copper-peptide skin regeneration, telomerase activation, mitochondrial support, and senescent-cell clearance. We ranked by the strength of the catalogued longevity evidence and by safety profile — clinical-tagged data beats preclinical, which beats anecdotes. Most picks are research compounds with no regulatory approval, and none reverse aging. Treat this as a map of the research landscape, not a prescription.
The Ranked List
Clinical-tagged skin-regeneration evidence — collagen and GAG synthesis, tighter skin — across 19 catalogued benefits; the safest injectable pick.
Reported dose: 1% topical or 1–2 mg SC
Half-life: Minutes to hours
Route: Topical/SC
Telomerase-activating peptide with preclinical telomere-elongation data and a 1.7-fold increase in melatonin-metabolite excretion; cycled 10-day protocols.
Reported dose: 5–10 mg daily for 10 days (cycled)
Half-life: 30 minutes
Route: SC/IM
Mitochondrial peptide (elamipretide) with clinical-tagged cardiolipin stabilisation and ATP support; investigational in the catalogue — not FDA-approved.
Reported dose: 40 mg daily
Half-life: Variable
Route: SC
Mitochondrial peptide with clinical-tagged neuroprotection against Aβ toxicity and a longevity association — the P3S variant is enriched in centenarians.
Reported dose: 1–5 mg daily
Half-life: 30 minutes
Route: SC
Cellular cofactor for energy metabolism and DNA repair; the gentlest profile of the set, though its longevity claims are anecdotal-tier.
Reported dose: 100–500 mg daily
Half-life: Short
Route: IV/SC/Oral
Senolytic peptide with a clinical-tagged senescent-cell elimination mechanism, but extremely limited safety data — research-settings only.
Reported dose: Research settings only — no established protocol
Half-life: Hours to days (D-amino acids confer stability)
Route: SC
Safety Note
Most compounds on this page are prescription drugs or research chemicals — not supplements. None of this content is medical advice: review each compound's full guide and safety note, respect WADA status if you compete, and consult a qualified clinician before making any health decision.
Frequently Asked Questions
Can I use these topically instead of injecting?
GHK-Cu has a well-documented topical route (1% formulations for skin regeneration). Epithalon, SS-31, humanin and NAD-plus are dosed parenterally in research; FOXO4-DRI is confined to specialised research settings.
Do these peptides reverse aging?
No. They target specific mechanisms — telomerase activation (epithalon), mitochondrial function (SS-31, humanin), senescent-cell clearance (FOXO4-DRI) — with mostly preclinical or early-clinical evidence. None reverse aging in any meaningful sense.
Is SS-31 FDA approved?
No. Despite some catalog flags, SS-31 (elamipretide) is an investigational compound with research-only status. Trust the research status over approval flags in the data.
What about Argireline and Matrixyl?
Those are topical cosmetic peptides — Argireline shows 48.9% anti-wrinkle efficacy versus 0% placebo in clinical-tagged data, and Matrixyl stimulates collagen — but they belong in the Skin & Beauty category, not longevity research.
