Building a Longevity Stack: Epithalon + NAD+ + SS-31 + MOTS-C

Why a Stack? The Hallmarks of Aging

In 2013, López-Otín et al. published a landmark paper in Cell identifying nine hallmarks of aging: genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication.

No single molecule addresses all nine. But four peptides — each targeting a different primary hallmark — can cover the most actionable mechanisms with remarkable efficiency.

The Four Pillars

Pillar 1: Telomere Maintenance — Epithalon

Target hallmark: Telomere attrition

Epithalon (Ala-Glu-Asp-Gly) activates telomerase via upregulation of hTERT gene expression. It also restores pineal gland function, normalises melatonin output, and modulates circadian gene networks.

• Primary effect: Extends telomeres, delays replicative senescence
• Secondary effects: Improved sleep quality, immune function, antioxidant enzyme expression
• Protocol: 5–10 mg/day subcutaneous, 10–20 day cycles, 2–3 times per year

Pillar 2: Cellular Energy — NAD+ (via NMN or direct IV)

Target hallmark: Mitochondrial dysfunction, epigenetic alterations

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in every living cell. It declines by roughly 50% between ages 40 and 60. NAD+ is the essential cofactor for:

• Sirtuins (SIRT1-7): Deacetylase enzymes that regulate DNA repair, mitochondrial biogenesis, inflammation, and fat metabolism

• PARPs: Poly-ADP-ribose polymerases that repair DNA single-strand breaks

• CD38: An ectoenzyme involved in immune regulation (and a major consumer of NAD+)

• Primary effect: Restores sirtuin activity, enhances DNA repair

• Secondary effects: Improved energy, better exercise recovery, enhanced cognitive clarity

• Protocol: Subcutaneous NAD+ injections (100–250 mg) 2–3 times per week, or NMN supplementation (250–500 mg daily)

Pillar 3: Mitochondrial Repair — SS-31

Target hallmark: Mitochondrial dysfunction (membrane-level)

While NAD+ addresses the signalling side of mitochondrial health, SS-31 addresses the structural side. It concentrates 5,000x in the inner mitochondrial membrane, stabilises cardiolipin, restores electron transport chain supercomplex assembly, and reduces ROS production at the source.

• Primary effect: Restores mitochondrial membrane integrity and ATP production
• Secondary effects: Improved cardiac function, exercise tolerance, reduced oxidative stress
• Protocol: 1–5 mg/day subcutaneous, 4–8 week cycles

Pillar 4: Metabolic Optimisation — MOTS-C

Target hallmark: Deregulated nutrient sensing

MOTS-C is a mitochondria-derived peptide (encoded by mitochondrial DNA) that activates AMPK — the master metabolic switch. It improves insulin sensitivity, enhances fat oxidation, regulates glucose metabolism, and has been shown to reverse age-related metabolic decline in animal models.

• Primary effect: Restores metabolic flexibility and insulin sensitivity
• Secondary effects: Weight management, exercise performance, reduced inflammation
• Protocol: 5–10 mg subcutaneous, 3–5 times per week, 4–8 week cycles

How Each Targets a Different Mechanism

Peptide	Primary Target	Aging Hallmark	Level of Action
Epithalon	Telomerase / hTERT	Telomere attrition	Nuclear DNA
NAD+	Sirtuins / PARPs	Epigenetic drift, DNA damage	Nuclear–mitochondrial signalling
SS-31	Cardiolipin / IMM	Mitochondrial dysfunction	Organelle membrane
MOTS-C	AMPK pathway	Nutrient sensing	Cellular metabolism

There is virtually no mechanistic overlap. Each peptide works at a different biological layer — from DNA (Epithalon) to nuclear signalling (NAD+) to organelle structure (SS-31) to whole-cell metabolism (MOTS-C).

Protocol Design: The 12-Week Longevity Cycle

Weeks 1–4: Foundation Phase

• SS-31: 2.5 mg/day subcutaneous (repair mitochondrial membranes first — this improves the efficacy of everything else)
• NAD+: 150 mg subcutaneous 3x/week (restore cofactor levels)
• MOTS-C: 5 mg subcutaneous 3x/week (activate metabolic pathways)

Weeks 5–6: Epithalon Cycle

• Epithalon: 10 mg/day subcutaneous for 10 consecutive days
• NAD+: Continue 150 mg 3x/week
• SS-31: Reduce to 1 mg/day maintenance or pause
• MOTS-C: Continue 5 mg 3x/week

Weeks 7–10: Consolidation Phase

• SS-31: Resume 2.5 mg/day
• NAD+: Continue 150 mg 3x/week
• MOTS-C: Continue 5 mg 3x/week

Weeks 11–12: Taper and Assess

• NAD+: Reduce to 2x/week
• MOTS-C: Reduce to 2x/week
• SS-31: 1 mg/day or stop
• Bloodwork: Comprehensive panel including fasting insulin, hsCRP, lipids, IGF-1, DHEA-S, complete metabolic panel

Adding GHK-Cu for Tissue-Level Rejuvenation

GHK-Cu (1–2 mg/day subcutaneous) can be added throughout the 12-week cycle for tissue-level gene modulation. Its 4,000+ gene effects complement the stack by addressing collagen synthesis, wound healing, antioxidant enzyme expression, and anti-inflammatory pathways at the tissue level — a layer not directly covered by the four core peptides.

Who This Stack Is For

This protocol is designed for:

• Adults 35+ experiencing early signs of aging (reduced energy, slower recovery, declining body composition)
• Biohackers and longevity enthusiasts who want a structured, evidence-based approach
• Athletes in their 40s–60s seeking to maintain performance and recovery
• Anyone with biomarker evidence of mitochondrial decline, metabolic dysfunction, or accelerated aging

Who Should Consult a Physician First

• Anyone with active cancer or a history of cancer (telomerase activation requires careful consideration)
• Those on blood-thinning medications
• Individuals with autoimmune conditions
• Pregnant or breastfeeding women

The Bottom Line

Aging is not one process — it is at least nine interconnected processes. Addressing just one is better than nothing, but true longevity optimisation requires a multi-target approach. Epithalon + NAD+ + SS-31 + MOTS-C provides four complementary pillars covering telomere maintenance, cellular signalling, mitochondrial structure, and metabolic regulation.
