Pharmaceutical-grade NAD+
The science

The metabolic advantage of injection, without the needle.

GLP-1 receptor agonists work. The delivery method, daily subcutaneous injection with significant nausea and muscle loss, is not a sustainable protocol for most people. GLP-4 delivers pharmaceutical-grade NAD+ through transmucosal absorption, bypassing digestion entirely.

The compound

NAD+ (10mg per spray)

One coenzyme, central to metabolism. NAD+ is the molecule your cells depend on to convert fuel into energy, regulate glucose, activate longevity pathways, and mobilize stored fat. Delivered intranasally or sublingually for absorption that bypasses first-pass metabolism.

Pathway 1 · Metabolic energy

Mitochondrial output

NAD+ is the primary electron carrier in cellular respiration. It drives the energy substrate cycle for sustained output rather than stimulant-driven peaks.

Pathway 2 · Insulin sensitivity

Glucose regulation

NAD+ supports insulin signaling and glucose handling, targeting the post-meal dynamics that drive fat storage and energy crashes.

Pathway 3 · Sirtuin activation

Longevity genes

Sirtuins (SIRT1, SIRT3) are NAD-dependent enzymes. Without NAD+ they cannot fire. This is the same longevity mechanism caloric restriction activates, metabolic efficiency at the gene expression level.

Pathway 4 · Lipolysis support

Fat mobilization

By restoring the metabolic machinery that releases stored fatty acids for energy, NAD+ supports the fat-mobilization cascade, replicating part of what injectable GLP-1 agonists achieve.

What exactly is in GLP-4?

A single active compound: pharmaceutical-grade NAD+ at 10mg per spray, 100 sprays per bottle (1,000mg total). No fillers, no stimulants, no proprietary blends.

How does this compare to injectable GLP-1 medications?

GLP-4 delivers NAD+ through a non-injection route. It is not a pharmaceutical substitute, it is a precision metabolic support protocol for individuals who want metabolic support without the clinical intervention.

Any nausea or muscle loss?

None. NAD+ supports metabolic pathways through a mechanism that does not produce nausea, vomiting, or the muscle catabolism associated with aggressive caloric restriction protocols.

Nasal or sublingual, is there a difference?

Equivalent bioavailability through both routes. Nasal is faster for acute application. Sublingual allows for more controlled dosing. Both bypass first-pass metabolism.
