NAD+ 500mg Dosage & Mixing Guide

What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of the body. It plays a critical role in cellular energy production, DNA repair, and regulating circadian rhythms. NAD+ levels naturally decline with age, which has made it a focus of longevity and anti-aging research.

Unlike precursor supplements (NMN, NR), injectable NAD+ delivers the molecule directly, bypassing digestive breakdown and allowing for rapid cellular uptake. Research applications include metabolic function, cognitive health, and cellular aging studies.

The 500mg vial is ideal for researchers beginning NAD+ protocols or those using lower-dose subcutaneous administration.

Quick Reference

Reconstitution Guide

Step-by-Step Instructions

1. Clean vial stoppers — Wipe with alcohol swabs
2. Draw 5mL BAC water — Using sterile syringe
3. Add to peptide vial — Inject slowly down the wall
4. Dissolve — Gently swirl until fully dissolved (2-5 minutes)
5. Label and refrigerate — Store immediately at 2-8°C

Concentration Calculations

With 500mg in 5mL BAC water:

• Concentration: 100mg/mL (100,000mcg/mL)
• Per unit (U-100): 1mg per unit

Suggested Protocols

Note: NAD+ protocols often begin with a loading phase followed by maintenance dosing.

Administration Methods

Subcutaneous Injection

Most common for self-administration research:

• Clean injection site with alcohol
• Pinch skin at abdomen, outer thigh, or upper arm
• Inject at 45-90° angle
• Inject slowly — NAD+ can cause temporary stinging
• Rotate injection sites

Intramuscular Injection

• Deltoid or gluteal muscle
• Inject slowly over 30-60 seconds
• Less common than SubQ

Slow IV Push (Research/Clinical Setting)

• Requires proper training and sterile technique
• Administered very slowly (over 30+ minutes)
• Higher doses typically given IV
• May cause flushing, warmth, or nausea if pushed too fast

What to Expect

During Administration

NAD+ injections may cause:

• Temporary stinging/burning at injection site (SubQ)
• Flushing or warmth sensation
• Chest tightness (if IV is too fast — slow down)
• Nausea (rare, usually dose or speed related)

These effects are typically mild and resolve within minutes. Injecting slowly significantly reduces discomfort.

Research Observations

• Energy: Increased cellular energy (ATP production)
• Cognition: Improved mental clarity reported
• Recovery: Enhanced physical recovery
• Sleep: Better sleep quality in some studies

Storage Requirements

Important: NAD+ is light-sensitive. Store in original vial and keep away from direct light.

Research Considerations

Mechanism of Action

• Sirtuin Activation — NAD+ is essential for sirtuin enzyme function (SIRT1-7)
• PARP Support — DNA repair enzyme activation
• Mitochondrial Function — ATP production and cellular energy
• Circadian Rhythm — Clock gene regulation

Research Applications

• Cellular aging and senescence
• Metabolic function studies
• Neurodegenerative research
• Mitochondrial dysfunction
• Addiction recovery research (NAD+ therapy)

Synergistic Compounds

NAD+ is often researched alongside:

• Resveratrol — Sirtuin activator
• Quercetin — Senolytic
• Fisetin — Senolytic
• TMG (Trimethylglycine) — Methyl donor support

NAD+ vs. Precursors

Injectable NAD+ bypasses the conversion steps required by oral precursors, providing direct cellular delivery.

Sourcing for Research

Source from verified suppliers that provide third-party testing and certificates of analysis (COA) for each batch. Compare purity documentation, shipping conditions, and batch traceability before purchasing research materials.
