Cognitive SupportNeuroprotectionCellular EnergyDual-Listed

What It Is

NAD+ is dual-listed here for its significant cognitive benefits. Beyond cellular energy, it's critical for neuronal health and cognitive function.

How It Works

NAD+ supports neuronal mitochondrial function, activates sirtuins involved in neuroprotection, and supports DNA repair in brain tissue.

Who It's For

Those seeking cognitive enhancement as part of a broader longevity protocol. See Longevity category for full details.

Who Should Avoid It

AUTO-DENY for active cancer and chemotherapy.

Protocol & Pricing

Pharmacy Price

$100

100mg/mL, 10mL vial (1000mg total)

You pay pharmacy price. No markup.

Starting Dose

50 units (50mg)

Form

Injectable vial, 10mL

Your pharmacy label will read

NAD+

100 MG/ML (10 ML)

The label shows strength per mL, not the total in the vial.

What that means

  • 100mg/mL means 100mg in every mL.
  • The vial holds 10mL, so 100mg/mL × 10mL = 1000mg in the vial.
  • Each 50-unit injection (0.5mL) gives you 50mg, about 20 injections per vial.

Dosing Protocol

See Longevity listing for full protocol details.

Beyond Use Date

90 Days from compounding (USP <797>)

A licensed U.S. 503A compounding pharmacy assigns this date and prints it on your vial label. Always follow the label.

Two doses of NAD+ Injectable, and what the evidence shows

From our medical director's protocol for NAD+ Injectable. Where the evidence is thin, it says so.

50 units (50 mg)

For patients new to NAD+.

When
Three times weekly
Order
1 vial
Supply
20 doses per vial, 46 days
Cost
$100 per vial

100 units (100 mg)

For patients already taking NAD+, or who have taken it before.

When

Supply
20 doses in 2 vials, 46 days
Cost
$200 for 2 vials

Why this dose

The protocol starts at 50 mg three times weekly for patients new to NAD+. Patients with prior NAD+ experience use 100 mg three times weekly.

At 50 mg, one vial provides about 20 doses. At 100 mg, two vials provide the same treatment period.

Slow administration is preferred. Flushing and chest tightness have been reported with faster NAD+ administration. Patients who experience persistent symptoms should contact their provider.

What the evidence shows

NAD+ plays an essential role in cellular energy production and metabolism. Human research has also studied several oral NAD+ precursors.

Subcutaneous NAD+ has received far less clinical study. No published trial has established an optimal subcutaneous dose or demonstrated benefits for energy, cognition, exercise recovery, or longevity in healthy adults.

Oral NAD+ precursors and injected NAD+ reach NAD metabolism through different biological pathways. Research has not established one route as superior for general wellness outcomes.

Some patients report changes in energy, mental clarity, or exercise recovery during treatment. Those experiences come from clinical practice rather than controlled NAD+ injection trials.

Each order also carries the $39 prescriber review. Pharmacy prices are the pharmacy's own; we add nothing to them.

NAD+ Injectable certificate of analysis

All 4 NAD+ Injectable samples tested for sterility and endotoxin passed both. Latest sample received by the lab Oct 12, 2026.

Every NAD+ Injectable batch dispensed by a licensed U.S. 503A compounding pharmacy is independently tested by Eagle Analytical Services (FDA-registered, A2LA ISO 17025 accredited). Sterility testing checks that nothing grows in the sample; the USP <85> endotoxin test checks for bacterial toxins that can cause fever.

How to get NAD+ Injectable prescribed online

NAD+ Injectable is available by prescription after an online medical review and dispensed for human use by a licensed 503A pharmacy. That is what separates it from research-use-only vials sold without a prescription. There is no membership, just a medical review fee per order, and automatic refills are optional.

  1. 1

    Complete a $39 medical review. Answer a short intake about your health history and your goals for NAD+ Injectable. The $39 fee is the only charge Rx Peps Direct collects, paid once, not a recurring subscription.

  2. 2

    A licensed provider reviews it. A US-licensed clinician reviews your intake and, if NAD+ Injectable is appropriate for you, writes a patient-specific prescription. The starting dose is typically 50 units (50mg).

  3. 3

    The pharmacy compounds and ships it. A licensed 503A compounding pharmacy in Texas compounds NAD+ Injectable and ships it pre-reconstituted by FedEx overnight in a reusable cooled case. Your fill is a 10mL injectable vial at 100mg/mL (1000mg total), labeled "NAD+ 100 MG/ML (10 ML)", and you pay the pharmacy $100 per vial at wholesale, with no clinic markup, plus a $15 flat FedEx overnight shipping fee charged by the pharmacy.

Common questions about NAD+ Injectable

Is the NAD+ injectable under Cognitive & Brain Health a different product?
No. It is the same product as the NAD+ injectable listed under Longevity & Anti-Aging: the same pharmacy vial (10 mL at 100 mg/mL, 1000 mg total), the same price, and the same label. It is listed again under Cognitive & Brain Health for patients whose main goal is focus and brain energy.
Is there a separate cognitive formulation of NAD+?
No. The active ingredient, concentration, vial size and price are identical; there is no separate cognitive formulation. Only the goal differs: brain energy and focus rather than systemic mitochondrial support. Your provider sets the dose schedule, whichever listing you order from.
How is NAD+ dosed for cognitive protocols?
The Rx Peps Direct starting dose for patients new to NAD+ is 50 units (50 mg) injected subcutaneously three times weekly (for example Monday, Wednesday, Friday). Patients already taking NAD+, or who have taken it before, can choose 100 mg three times weekly, which is ordered as two vials. Either order lasts about 46 days. A licensed U.S. 503A compounding pharmacy compounds the formulation against Rx Peps Direct prescriptions. As with all NAD+ injections, push slowly to minimize flushing or chest pressure.
How do I inject NAD+?
Subcutaneously into the abdomen, upper outer thigh, or back of the upper arm using a 31-gauge, 5/16-inch needle on a U-100 insulin syringe. Push slowly over 30 to 60 seconds. Sterile syringes are included with every Rx Peps Direct shipment.
How is the NAD+ injectable supplied?
Compounded by a licensed U.S. 503A compounding pharmacy under a patient-specific prescription. Ships pre-reconstituted and ready to inject in cold-chain packaging. Every batch is tested by Eagle Analytical Services; the Certificate of Analysis is published on this product page.
