CLASSIFICATION
Coenzyme; dinucleotide found in all living cells. Essential cofactor for hundreds of metabolic reactions. Not a peptide — a small molecule coenzyme derived from niacin (vitamin B3).
MECHANISM
Directly fuels the electron transport chain (NADH → ATP). Activates sirtuins (SIRT1–7) — longevity proteins that regulate DNA repair, inflammation, and metabolism. Activates PARP1 for DNA strand break repair. Activates CD38/CD157 ectoenzymes.
WHY INJECT
Oral NAD+ precursors (NMN, NR) require cellular conversion. IV/SC NAD+ delivers the active molecule directly — bypasses conversion steps, achieves higher acute plasma/intracellular levels. Particularly relevant for neurological and addiction recovery protocols.
DISCOVERY
Discovered by Arthur Harden & William Young (1906). Nobel Prize 1929. The role of NAD+ decline in aging established by David Sinclair, Johan Auwerx, and Charles Brenner — 2013–2016.
NAD+ DECLINE WITH AGE
NAD+ levels decline ~50% between age 20 and 60. This decline correlates with reduced mitochondrial function, increased DNA damage accumulation, metabolic dysfunction, and neurodegeneration. Restoration = core anti-aging target.
02 / RESEARCH HISTORY

Development Timeline

1906
Arthur Harden and William Young discover a "coferment" required for alcoholic fermentation — later identified as NAD+. Nobel Prize in Chemistry awarded 1929 to Harden and Hans von Euler-Chelpin for this work.
1930s–1960s
NAD+ established as central redox cofactor in cellular metabolism — NADH/NAD+ ratio governs glycolysis, TCA cycle, and oxidative phosphorylation. Pellagra (niacin deficiency) understood as NAD+ depletion disease.
2000
Leonard Guarente (MIT) discovers sirtuins — the first SIRT1 described as an NAD+-dependent deacetylase that regulates caloric restriction longevity effects in yeast. Sirtuins require NAD+ as a cofactor — establishing NAD+ as a longevity signaling molecule, not just an energy carrier.
2013
David Sinclair lab (Harvard) publishes landmark Cell paper: NAD+ decline with age disrupts SIRT1 regulation, causing muscle mitochondrial dysfunction. Restoring NAD+ in aged mice reverses muscle aging biomarkers to that of young mice within one week. Media: "Fountain of Youth Molecule."
2016–2020
Johan Auwerx (EPFL) shows NAD+ restoration improves mitochondrial function in models of muscular dystrophy, NAFLD, and neurodegeneration. Charles Brenner (University of Iowa) develops NR (nicotinamide riboside) as oral precursor; human trials confirm blood NAD+ elevation. NMN (nicotinamide mononucleotide) gains massive popularity.
2019–2024
IV NAD+ therapy popularized in addiction recovery, anti-aging clinics, and functional medicine. Protocols established for addiction withdrawal (opioid, alcohol, benzos) — NAD+ reduces neurological cravings and withdrawal severity. Human studies confirm safety of IV NAD+ at 500–1500mg doses.
03 / BENEFITS

Primary Effects

01
Mitochondrial Function & Energy Production
NAD+ is the terminal electron acceptor in the mitochondrial electron transport chain — NADH donates electrons to Complex I, producing the proton gradient that drives ATP synthesis. Elevated NAD+ directly increases mitochondrial efficiency, ATP output, and metabolic capacity. Users report dramatic energy increases within hours of IV administration.
02
DNA Repair Activation (PARP)
PARP-1 (poly-ADP-ribose polymerase) is the primary DNA damage repair enzyme — it consumes NAD+ as a substrate. Elevated NAD+ dramatically accelerates detection and repair of DNA strand breaks, preventing mutation accumulation. Critical for cancer prevention and cellular longevity.
03
Sirtuin Activation (SIRT1–7)
Sirtuins are the longevity proteins that regulate gene expression, inflammation, metabolism, and stress response. SIRT1: fat mobilization, inflammation suppression. SIRT3: mitochondrial function. SIRT6: DNA repair, telomere maintenance. All require NAD+ — low NAD+ = low sirtuin activity = accelerated aging.
04
Neurological Recovery & Addiction
The most clinically established use of IV NAD+. Addiction medicine clinics report 70–85% reduction in withdrawal symptoms for opioid, alcohol, and benzodiazepine dependence with 10-day IV NAD+ protocols. Mechanism: restores depleted neuronal NAD+ levels that are critically low in addiction states, restoring normal dopamine signaling.
05
Anti-Aging & Longevity
Addresses the root biochemical mechanism of aging: NAD+ decline → sirtuin silencing → epigenetic dysregulation → hallmarks of aging. Studies in aged animals show reversal of vascular aging, improved muscle function, restored memory, and extended lifespan. Human data accumulating but still limited to surrogate endpoints.
06
Cognitive Enhancement & Neuroprotection
NAD+ is essential for neuronal energy metabolism and is dramatically lower in neurodegenerative conditions (Alzheimer's, Parkinson's). Restoration improves synaptic plasticity, reduces neuroinflammation, and protects against excitotoxicity. Users report improved mental clarity, focus, and cognitive performance within 24–72 hours of IV administration.
04 / RECONSTITUTION

Preparation Protocol

// 1,000MG VIAL — MILLIGRAM-SCALE RECONSTITUTION
1,000 mg ÷ 3.0 mL BAC water = 333 mg/mL
Add 3.0 mL (300 units) bacteriostatic water to 1000mg lyophilized vial. NAD+ is dosed in milligrams (not micrograms) — work in mL volumes, not unit counts.
IMPORTANT — Milligram Scale: NAD+ is NOT dosed in micrograms. Do not use the standard "units" method. Work in mL volumes directly from the 333 mg/mL concentration. Example: 500mg dose = 1.5 mL draw.
TARGET DOSE VOLUME TO DRAW ROUTE NOTE
LOW250 mg 0.75 mL SC or IV slow Maintenance / SC protocol starting point
STANDARD500 mg 1.50 mL IV (slow drip) or SC split Standard clinic protocol; well-tolerated
HIGH750 mg 2.25 mL IV slow drip (≥2 hours) Anti-aging / neurological protocols
MAX1,000 mg 3.0 mL (full vial) IV slow drip (3+ hours) Addiction protocol / maximum anti-aging
IV Rate Critical: NAD+ IV MUST be administered slowly — typically over 2–4 hours for 500–1000mg doses. Rapid infusion causes intense, unpleasant side effects: chest tightness, flushing, nausea, muscle cramps, shortness of breath. Slow the drip if any of these occur. All effects resolve when infusion is slowed.
SC Alternative: For home use, NAD+ can be administered subcutaneously in smaller doses (100–250mg split across 2 sites). Less dramatic acute effect than IV but avoids infusion logistics. Well-tolerated route for maintenance protocols.
Storage: Lyophilized — refrigerate (2–8°C), protect from light and moisture. Critical: NAD+ is unstable once reconstituted. Use within 24 hours of reconstitution. Do not pre-reconstitute and store. Reconstitute fresh for each use.
05 / DOSING PROTOCOL

Administration Guide

PROTOCOL DOSE FREQUENCY DURATION CONTEXT
MAINTENANCE 250 mg SC 2–3×/week Ongoing Anti-aging baseline; home protocol
LOADING 500 mg IV Daily × 5–10 days 1–2 weeks Initial repletion; anti-aging boost
ADDICTION 750–1000 mg IV Daily × 10 days 10 days Opioid/alcohol/benzo withdrawal support
PERFORMANCE 250–500 mg SC 1–2×/week 12+ weeks Energy, cognition, athletic recovery
Synergy with NMN/NR: Many protocols combine IV/SC NAD+ loading with daily oral NMN (500–1000mg) or NR (500mg) for sustained NAD+ precursor availability between injections. The oral precursors maintain elevated NAD+ between IV/SC sessions.
06 / TIMING

Administration Timing

PREFERRED WINDOW
Morning — NAD+ activates energy production and cognitive pathways. Evening administration can cause sleep disruption in some users (increased energy and metabolic activation).
FOOD STATE
Fasted (or light meal) preferred for IV protocols. GI discomfort during infusion is worsened by a full stomach. SC dosing is less sensitive to food state.
POST-EXERCISE
Excellent timing — exercise depletes cellular NAD+ via PARP activation. Post-workout SC NAD+ replenishes depleted stores and amplifies recovery signaling.
IV DURATION
500mg: minimum 90–120 min. 750mg: 2–3 hours. 1000mg: 3–4 hours. Never rush NAD+ infusion — chest tightness and intense discomfort result. Slow drip = better experience.
FREQUENCY NOTES
Anti-aging: 1–2×/month IV loading + daily oral NMN. Performance: 2–3×/week SC. Addiction: daily for 10 days then transition to 2×/week SC maintenance.
STACKING
Excellent with SS-31 (mitochondrial synergy — different targets). Pairs with Glutathione IV for comprehensive cellular detox + energy restoration protocol.

5–10
DAYS INITIAL IV
Ongoing
MAINTENANCE
2–3×
SC/WEEK (MAINT.)
Loading Phase (Week 1–2): 500mg IV daily for 5–10 consecutive days. This achieves rapid tissue repletion. Clinic setting preferred for first 2–3 infusions — monitor for infusion reactions. After tolerance established, continue at home with proper IV setup or transition to SC.
Maintenance Phase (Ongoing): 250–500mg SC, 2–3×/week. OR monthly 500–1000mg IV "recharge" sessions combined with daily oral NMN (500–1000mg). Both approaches maintain elevated whole-blood NAD+ levels.
Performance Add-On: 250mg SC 30 minutes pre-workout on training days. Enhances mitochondrial energy production during exercise and accelerates post-workout recovery. Compatible with all other Apex peptides.
Longevity Stack: NAD+ IV/SC + SS-31 (mitochondrial membrane protection) + Epitalon (telomere extension + sirtuin activation) + GHK-Cu (tissue remodeling) = comprehensive cellular anti-aging protocol targeting multiple hallmarks of aging simultaneously.
Notice: IV NAD+ is available through licensed medical providers and functional medicine clinics. SC administration requires proper training and sterile technique. NAD+ is not FDA-approved as a drug (it is a naturally occurring coenzyme). IV administration carries small infection and air embolism risk — sterile technique is mandatory. Monitor uric acid with high-dose protocols. Not recommended during pregnancy or breastfeeding.
