Best Peptides for Anti-Aging & Longevity

Top anti-aging peptides backed by research - epitalon, GHK-Cu, thymosin alpha-1 and more for cellular rejuvenation.

GHK-Cu

A naturally occurring copper-binding tripeptide that declines with age. Promotes collagen synthesis, wound healing, and has broad regenerative effects on skin, hair follicles, and tissues.

Dose: 1-3 mg topical ยท 200-500 mcg injectable | Route: Topical cream/serum or subcutaneous injection

Thymosin Alpha-1

A thymic peptide approved in over 35 countries for immune modulation. Enhances T-cell function, dendritic cell maturation, and anti-viral/anti-tumor immunity without overstimulation.

Dose: 1.6-3.2 mg | Route: Subcutaneous injection

FOXO4-DRI

A D-retro-inverso peptide that disrupts FOXO4-p53 interaction in senescent cells, triggering selective apoptosis of senescent cells while sparing healthy cells.

Dose: 5-10 mg/kg (animal studies) | Route: Subcutaneous

MOTS-c

A mitochondria-derived peptide that acts as an exercise mimetic, improving metabolic homeostasis, insulin sensitivity, and fat oxidation. Levels decline significantly with age.

Dose: 5-10 mg | Route: Subcutaneous injection

Copper Peptides

A family of small peptides complexed with copper ions that stimulate collagen synthesis, wound healing, and skin remodeling. Beyond GHK-Cu, includes AHK-Cu and other tripeptide-copper complexes.

Dose: 1-3% topical solution | Route: Topical

Matrixyl

A lipopeptide of palmitic acid linked to pentapeptide KTTKS. One of the most researched anti-aging cosmeceutical peptides, stimulating collagen and fibronectin.

Dose: 2-8% in serum/cream | Route: Topical

Argireline

A synthetic hexapeptide that mimics SNAP-25 protein. Often called "topical Botox," it reduces expression lines by inhibiting neurotransmitter release at neuromuscular junctions.

Dose: 5-10% solution | Route: Topical

Leuphasyl

A pentapeptide mimicking enkephalin that binds enkephalin receptors on nerve cells, reducing neural excitability and complementing argireline for enhanced anti-wrinkle effects.

Dose: 3-5% solution | Route: Topical

SNAP-8

An elongated version of argireline (8 vs 6 amino acids) providing enhanced SNARE complex inhibition for superior wrinkle reduction.

Dose: 3-10% solution | Route: Topical

Palmitoyl Tripeptide-1

A lipopeptide acting as a matrikine, signaling skin repair by mimicking collagen breakdown products that trigger fibroblast collagen production.

Dose: 2-5% in formulation | Route: Topical

Palmitoyl Tetrapeptide-7

A lipopeptide that reduces IL-6 secretion and inflammaging. Often paired with Pal-Tripeptide-1 as "Matrixyl 3000" for combined collagen-building and anti-inflammatory action.

Dose: 2-4% in formulation | Route: Topical
