— Mechanism / 01

Cellular currency. Replenished.

NAD+ isn't a peptide — it's the universal cellular coenzyme that every metabolic and longevity protocol routes through. Element MD ships pharmaceutical-grade NAD+ with the same lab QC as our peptide line.

Energy metabolism

NAD+ is the electron acceptor in mitochondrial energy production. Levels decline with age; restoration reverses several downstream signals.

Effect · Primary

Sirtuin signaling

SIRT1–7 require NAD+ as substrate. The gene-regulatory machinery of healthy aging.

Effect · Secondary

DNA repair

PARP-driven DNA repair consumes NAD+. Adequate levels keep the repair machinery operating.

Effect · System
— Reference protocol / 02

Trial-aligned titration ladder.

This is the published Phase 2 escalation pattern, not a dosing recommendation. Adjust under qualified guidance based on tolerability and research goals. Open the dosing calculator below to convert mg to units.

Subcutaneous100 mg

Daily SC. The most-tolerated route.

IV500 mg

Slow IV push, weekly. Higher dose, more flushing.

Cycle mg

Most run 4-week loading + 8-week maintenance.

— What ships / 03

The complete research kit.

Every Element MD box ships with everything needed to reconstitute and run the protocol. We don't fragment the workflow into upsells — the kit is the kit.

Element MD makes NAD+ a non-event.

Daily SC. Mental energy, recovery between training, sleep. Consistent across two reorders.

Pharma-grade. The QC is the difference.

Tried three NAD+ vendors. Element MD is the one whose flushing profile matches what NAD+ should feel like.

Stacked under epitalon, MOTS-c.

Three-peptide longevity stack. NAD+ is the spine. Element MD's consistency keeps it that way.

Switched from a compounded source. Half the cost, twice the documentation.

Element MD is the one whose batch consistency I have not had to question. Reorder is automated and the COA on top of every box matches the database.

— Common questions / 05

Before you order. Before you reconstitute.

SC vs IV?
SC is more tolerated and self-administered; IV pushes a bigger bolus and produces more flushing.
Stack with epitalon or MOTS-c?
Yes — the canonical longevity stack.
Independent COA?
Every batch ISO-17025 tested.
What's your cold-chain process?
Lyophilized peptide is stable at room temperature for short transit, but we ship every order with insulated mailers and gel packs sized to the destination. Average arrival temperature on cross-country routes is 4.7°C.
How do I cancel a subscription?
From your account dashboard, in two clicks. No retention call, no email loop. Pause, skip, or cancel any time before the next ship date.
