What are the best peptides for longevity?

The top longevity peptides include Epithalon (telomerase activation), SS-31/Elamipretide (mitochondrial health), MOTS-c (metabolic regulation), and Thymosin Alpha-1 (immune rejuvenation). Each targets different aging pathways for comprehensive anti-aging benefits.

What is MOTS-c peptide?

MOTS-c is a mitochondrial-derived peptide that acts as a metabolic regulator. It improves insulin sensitivity, promotes fat oxidation, and has exercise-mimetic effects. Research shows it can improve metabolic health and has anti-aging properties at the cellular level.

How does SS-31 work for mitochondria?

SS-31 (Elamipretide) specifically targets cardiolipin in the inner mitochondrial membrane. It reduces oxidative stress, improves electron transport chain efficiency, and enhances ATP production. It

What is NAD+ and why is it important for aging?

NAD+ (nicotinamide adenine dinucleotide) is a crucial coenzyme for cellular energy production, DNA repair, and sirtuin activation. NAD+ levels decline with age, contributing to mitochondrial dysfunction and aging. NAD+ precursors like NMN and NR can restore levels.

What does Epithalon do for telomeres?

Epithalon activates telomerase, the enzyme that lengthens telomeres—the protective caps on chromosomes. Telomeres shorten with each cell division, limiting cellular lifespan. By activating telomerase, Epithalon may help preserve cellular youth and extend healthy lifespan.

Can peptides help with energy and fatigue?

Yes, mitochondrial peptides like SS-31 and MOTS-c directly target cellular energy production. By improving mitochondrial function and reducing oxidative stress, they can enhance ATP production and reduce fatigue. NAD+ support also improves cellular energy.

What is Thymosin Alpha-1 used for?

Thymosin Alpha-1 is an immune-modulating peptide that enhances T-cell function and immune surveillance. It

What blood tests should I get for longevity?

Key longevity markers include fasting insulin and HbA1c (metabolic health), hs-CRP and homocysteine (inflammation), lipid panel (cardiovascular), IGF-1 and DHEA-S (hormones), and vitamin D. Advanced panels may include oxidative stress markers and telomere length testing.
