The Protocol
The mechanism.
01
STAG NAD+
NAD+ Resveratrol Quercetin
Three longevity compounds in one capsule. NAD+ at 500mg per serving supports cellular energy production and DNA repair. Resveratrol and Quercetin extend the sirtuin activation pathway.
NAD+ (Nicotinamide Adenine Dinucleotide)500mg
Quercetin Dihydrate Extract250mg
Japanese Knotweed Extract (98% Resveratrol)150mg
02
STAG Eternal
NMN 500mg
Beta-Nicotinamide Mononucleotide at 500mg per capsule. NMN is an NAD+ precursor — it raises intracellular NAD+ levels more effectively than NAD+ taken directly due to cellular transport mechanisms.
Beta-NMN (Nicotinamide Mononucleotide)500mg
03
STAG Multi
Complete Men's Multivitamin
Full-spectrum men's multivitamin covering the micronutrient deficiencies most common in men over 40. The nutritional foundation the other two products build on.
Vitamin D32000IU
Vitamin B121000mcg
Magnesium100mg
Zinc15mg

Why It Works
Mechanism, not marketing.

NAD+ declines approximately 50% between ages 40 and 60. That decline is linked to reduced energy, slower DNA repair, impaired mitochondrial function, and accelerated cellular ageing.

The NAD+/NMN combination is deliberate. NAD+ taken orally is partially degraded before reaching cells. NMN (its precursor) crosses cell membranes more efficiently and converts to NAD+ intracellularly — raising actual cellular NAD+ levels more effectively.

Multi provides the micronutrient foundation. Vitamin D, B12, zinc, and magnesium deficiencies are endemic in men over 40. Without addressing these, the more targeted interventions underperform.

01
NAD+ Restoration
Dual-pathway approach — direct NAD+ plus NMN precursor — targets intracellular NAD+ restoration more effectively than either alone.
02
Sirtuin Activation
Resveratrol and Quercetin activate sirtuin pathways that depend on NAD+ — extending the longevity signalling cascade.
03
DNA Repair
Adequate NAD+ is required for PARP enzyme function — the primary DNA repair mechanism. Decline in NAD+ slows repair.
04
Micronutrient Foundation
Multi addresses the deficiencies that cause most supplement protocols to underperform — D3, B12, zinc, and magnesium.

Common Questions
FAQ
When do I take each product?
NAD+ and Eternal: both taken in the morning with food. Multi: with breakfast. All three can be taken together.
How long does the longevity protocol take to work?
Cellular changes take time. Most men notice energy improvements within 2–4 weeks. The deeper longevity benefits — DNA repair, mitochondrial function — are measured in months, not weeks. This is a long-term protocol.
Is NMN safe?
NMN has an extensive safety profile in human trials. No serious adverse effects have been reported at doses up to 1250mg/day.
How does shipping work?
Fulfilled by Supliful from the US. Australia delivery 7–14 business days. Free shipping over $80.
What's the return policy?
30-day money-back guarantee. No hassle.

STAG D3
STAG D3
Vitamin D3 5000IU + K2. Most men are deficient.
STAG Mag
STAG Mag
Magnesium glycinate for sleep and recovery.
