What is NAD+?

Nicotinamide Adenine Dinucleotide (CAS: 53-84-9)

NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in every living cell. It is indispensable for two fundamental biological operations: converting nutrients into cellular energy (ATP) and acting as a fuel source for enzymes that repair DNA and control cellular aging.

The Age-Related NAD+ Collapse: By age 50, average NAD+ levels decline by roughly 50%, primarily because the body consumes it faster than it can synthesize it. This drop is a major driver of mitochondrial dysfunction, slower cellular repair, and metabolic decline.

Four Core Biological Functions

1. Cellular Energy (Redox Engine)

In mitochondria, NAD+ picks up electrons from food metabolism to become NADH, carrying them to the electron transport chain to generate ATP energy. The NAD+/NADH ratio determines metabolic efficiency.

2. DNA Repair via PARPs

When DNA suffers damage from UV light, oxidative stress, or toxins, enzymes called PARP-1 consume large amounts of NAD+ to rebuild and repair the double-helix strands.

3. Longevity via Sirtuins

Sirtuins (SIRT1–SIRT7) are protective enzymes regulating mitochondrial biogenesis, circadian rhythm, and anti-inflammation. Sirtuins cannot function without consuming NAD+.

4. The CD38 Inflammaging Bottleneck

As chronic low-grade inflammation rises with age ("inflammaging"), the immune enzyme CD38 becomes hyperactive, degrading vast amounts of NAD+ and starving cellular repair systems.

Delivery Methods Comparison: Injections, IVs & Oral Precursors

Method Typical Dosage How It Works & Key Trade-Offs
Subcutaneous (SubQ) Injection 25 mg – 100 mg (2–4x / week) High Bioavailability. Bypasses liver first-pass metabolism. Delivers direct NAD+ systemically. Can cause localized transient cramping if injected too quickly.
Intravenous (IV) Infusion 250 mg – 1,000 mg (sessions) Rapid Saturation. Delivers high doses straight to bloodstream. Requires slow drip (1.5 to 3+ hours) to prevent intense chest tightness and nausea.
Oral Precursors (NMN / NR) 300 mg – 1,000 mg daily Gentle & Sustained. Oral NMN and NR are smaller precursor molecules absorbed and assembled into NAD+ by cells.
Oral Direct NAD+ 100 mg – 500 mg daily Low Direct Absorption. Standard oral NAD+ breaks down into basic Vitamin B3 (nicotinamide) in gut unless using liposomal delivery.

Subcutaneous (SubQ) NAD+ Titration & Math

SubQ NAD+ provides high systemic bioavailability without requiring a 2–3 hour IV drip. Because NAD+ rapidly engages adenosine receptors and stimulates smooth muscle contraction, following a gradual titration schedule prevents acute discomfort.

1. Clinical Step-by-Step Titration Schedule

Phase Duration Dosage Frequency Primary Goal
Week 1: Test Phase Days 1–7 20 mg – 25 mg 2–3x / week (Mon/Thu) Test sensitivity; minimize initial chest/abdominal physical sensations.
Week 2: Ramp-Up Days 8–14 40 mg – 50 mg 2–3x / week (Mon/Wed/Fri) Gradual tissue adaptation and metabolic uptake.
Weeks 3–4: Target Dose Days 15–28 75 mg – 100 mg 2–3x / week Core cellular repletion, energy support, DNA repair signaling.
Maintenance Ongoing / Cycled 50 mg – 100 mg 1–2x / week Long-term mitochondrial maintenance.

2. Reconstitution & Syringe Math (500 mg & 1,000 mg Vials)

Syringe Unit Measurements (U-100 Insulin Syringe):
500 mg Vial (Reconstituted with 5.0 mL BAC Water = 100 mg/mL):
  • 25 mg dose: Draw to 25 units (0.25 mL)
  • 50 mg dose: Draw to 50 units (0.50 mL)
  • 75 mg dose: Draw to 75 units (0.75 mL)
  • 100 mg dose: Draw to 100 units (1.0 mL)
1,000 mg Vial (Reconstituted with 5.0 mL BAC Water = 200 mg/mL):
  • 25 mg dose: Draw to 12.5 units (0.125 mL)
  • 50 mg dose: Draw to 25 units (0.25 mL)
  • 100 mg dose: Draw to 50 units (0.50 mL)

3. Practical Rules to Minimize the "NAD+ Rush"

The Physical Sensation: Within 1–3 minutes of injecting, users may feel transient chest tightness, abdominal cramping, flushing, or lightheadedness due to rapid smooth-muscle adenosine receptor activation. These resolve in 5–10 minutes.
  • Inject in the Morning: NAD+ boosts mitochondrial ATP output and central nervous system alertness. Injecting late in the afternoon or evening causes insomnia.
  • Inject Very Slowly: Depress the plunger steadily over 20 to 30 seconds. Rapid delivery spikes blood concentration and triggers stronger cramping.
  • Warm the Syringe: Let the drawn syringe sit at room temperature for 5–10 minutes. Cold liquid straight from the fridge exacerbates burning.
  • Injection Sites: SubQ belly fat (2 inches away from navel) or outer upper thigh. Rotate sites with each dose.
  • Split Large Doses: If injecting 100 mg or more, split into two 50 mg injections in opposite flanks to reduce localized volume pressure.

The Methylation Connection: TMG (Trimethylglycine)

When excess NAD+ is broken down, it produces nicotinamide (NAM). The liver uses the enzyme NNMT (nicotinamide N-methyltransferase) to attach a methyl group before excreting it in urine.

Why TMG Co-Supplementation is Mandatory:

High-dose NAD+ injections heavily draw down your body's available methyl pool. To prevent methyl depletion, clinicians recommend taking 500 mg to 1,000 mg of oral TMG (Trimethylglycine / Betaine) daily with a meal during an active NAD+ protocol to preserve methyl donors, support liver detoxification, and prevent homocysteine elevation.

Stacking NAD+ with GHK-Cu & BPC-157

Circadian Split Protocol & Syringe Isolation Rules

SubQ NAD+ can safely be run alongside peptide protocols like GHK-Cu and BPC-157 because they operate through distinct biological pathways. However, strict execution rules must be followed:

THE GOLDEN RULE: NEVER MIX NAD+ IN THE SAME SYRINGE

NAD+ solutions have an acidic pH (~3.0–4.0) for liquid stability. Drawing GHK-Cu or BPC-157 into the same barrel as NAD+ will degrade the delicate peptide chains and disrupt copper binding. NAD+ must ALWAYS be injected on its own in its own separate syringe. (BPC-157 and GHK-Cu *can* be combined together in their own separate syringe).

Circadian AM / PM Split Schedule

MORNING (AM): The NAD+ Window

Spikes cellular alertness and ATP. Take early to support daytime energy and avoid sleep disruption.

  • Inject SubQ NAD+ (25–100 mg) slowly over 20–30s.
  • Take 500–1,000 mg oral TMG with breakfast.
EVENING (PM): The Peptide Window

Growth hormone secretion and cellular tissue remodeling naturally peak during deep sleep cycles.

  • Inject GHK-Cu (1–2 mg) + BPC-157 (250–500 mcg) SubQ.
  • Take 15–30 mg oral Zinc Bisglycinate with dinner.

Weekly Cycle Coordination Table

Compound Weekly Frequency Cycle Length Rest Period
SubQ NAD+ 2 to 3 days / week (Mon/Wed/Fri) 4 to 8 weeks 2 to 4 weeks off (or 1x/wk maintenance)
BPC-157 Daily or 5 days on / 2 days off 4 to 8 weeks 4 weeks off
GHK-Cu Daily or 5 days on / 2 days off 30 to 45 days max 30 days off (copper clearance)
Master Daily Routine (Semax + Selank + SubQ NAD+ + GHK-Cu + BPC-157):
Full Master Protocol & FDA Table >

Combines AM Semax (BDNF focus) & AM SubQ NAD+ (energy), Midday Selank (stress buffer), and PM GHK-Cu + BPC-157 (collagen remodeling & sting relief).

Symptom Troubleshooting Guide

Side effects like fatigue, headaches, or nausea are almost always linked to acute methyl donor depletion, rapid titration, trace mineral shifts, or dose timing:

1. Unexplained Fatigue or "Brain Fog"

Cause: Methyl donor depletion from clearing NAD+ breakdown products.
Fix: Increase TMG to 500–1,000 mg daily with morning meal. Add methylated B-vitamins. Drop NAD+ dose by 50% for 3–5 days to let system rebalance.

2. Headaches or Feeling "Wired yet Tired"

Cause: Over-stimulation, vascular modulation, or dose timing.
Fix: Increase water & electrolytes (sodium, potassium, magnesium). Shift NAD+ injection to early morning before noon.

3. Nausea or Metallic Taste

Cause: GHK-Cu copper accumulation OR taking zinc on an empty stomach.
Fix: Always take oral zinc with a full meal containing protein/fat. Pause GHK-Cu for 3–5 days while continuing 15–30 mg zinc with food.

The 3-Step "Reset" Adjustment Protocol

Action Step Protocol Adjustment Expected Outcome
1. Drop NAD+ Dose by Half If at 50–100 mg, drop back to 20–25 mg (or skip 1–2 doses). Alleviates methylation strain and smooth-muscle tension in 24–48 hours.
2. Temporarily Isolate Peptides Pause GHK-Cu for 3 days while keeping BPC-157 steady. Identifies if copper accumulation is the root cause.
3. Re-introduce One at a Time Raise one compound back up every 4–5 days. Pinpoints exact individual threshold for each compound.

Blood Work & Clinical Biomarkers

Targeted blood testing ensures liver clearance capacity, methylation status, and trace mineral balance remain healthy throughout your protocol.

Panel / Marker What It Measures Target / Clinical Importance
Fasting Homocysteine Primary indicator of methyl donor status. Key Flag >10–12 µmol/L: Indicates NAD+ metabolism is draining methyl pool faster than replenished. Requires TMG increase.
Serum Copper & Serum Zinc Circulating trace mineral equilibrium. Ideal Ratio 0.8:1 to 1.2:1 (Zinc to Copper). Prevents copper excess from GHK-Cu.
Ceruloplasmin Primary copper-transport blood protein. Evaluates liver copper binding & synthesis capacity.
Comprehensive Metabolic Panel (CMP) Liver enzymes (AST, ALT) & Kidney markers (eGFR, BUN). Evaluates hepatic and renal clearance capacity for peptide breakdown products.
Complete Blood Count (CBC) Red/white blood cells & platelets. Baseline check for overall immune health and bone marrow function.
