NAD+ Nasal Spray

The molecule is identical — both deliver NAD+ to systemic circulation. The injection is the highest-bioavailability format and uses larger weekly doses (typically 100–250 mg subcutaneously, 1–2× weekly). The nasal spray uses smaller per-dose strengths (typically 50–100 mg per spray, dosed daily) and trades peak bioavailability for needle-free convenience and faster, more frequent on-demand use. Many patients pick one based on lifestyle, not just biology.

Patients commonly report a noticeable shift in mental clarity, alertness, or warmth within minutes of dosing. The intranasal route bypasses first-pass hepatic metabolism, which is why onset is faster than oral NAD+ precursors like NR or NMN. Cumulative effects on energy, sleep quality, and recovery typically build over 2–4 weeks of consistent daily use.

Yes. Most protocols are dosed daily, 1–3 times per day depending on goals and tolerance. A common pattern is 1–2 sprays per nostril in the morning and early afternoon, avoiding late-day dosing because some patients find NAD+ stimulating. Your prescribing doctor will set your daily total based on your goals and how you respond.

Mild nasal irritation, brief burning, or sneezing is the most commonly reported side effect, especially in the first week. Most patients adapt within a few days. Alternating nostrils, blowing your nose before dosing (not after), and avoiding overlap with nasal decongestants or saline rinses help. Persistent irritation, recurrent nosebleeds, or significant discomfort should be reported to your doctor.

Some patients use the injection 1–2× weekly as the primary protocol and the nasal spray as an on-demand format for focus during the day or while traveling. This is a doctor-supervised decision — your prescribing doctor will set total NAD+ exposure across both routes to avoid stacking effects, and may simplify to one format if symptoms or labs suggest it.

The metered nasal spray bottle is small, does not require refrigeration in short-term use, and contains no needles or syringes — so it travels well in carry-on bags and clears most security screening as a personal medication. Carry it in original packaging with your prescription label visible. For international travel, check destination country regulations for compounded prescriptions.

A single compounded bottle typically delivers 30–60 days of dosing depending on your prescribed daily total (number of sprays per dose × times per day). At 4 sprays/day a bottle generally lasts a full month; at higher daily totals it lasts proportionally less. Your prescription is set up to auto-ship in 30-day cycles aligned to your protocol so you do not run short.

Peptide12 partners with state-licensed compounding pharmacies that hold state and federal licensure and undergo regular USP <797> sterility audits. Every batch is third-party tested for identity, potency, sterility, and endotoxin before release. Compounded NAD+ nasal spray is not FDA-approved as a finished drug product but is prepared from FDA-regulated active ingredients under individualized prescription.
