Telemedicine in Illinois.

Illinois permits telehealth prescribing under the Illinois Telehealth Act (225 ILCS 150). An Illinois-licensed physician can establish the patient relationship through online intake review — no in-person visit is required for peptide or GLP-1 prescribing. Pepti is available in all 50 states and Washington, D.C.

The Chicago metro is one of the largest telehealth markets in the Midwest, with strong GLP-1 and peptide-therapy demand.

Your protocol

How NAD+ Injection is prescribed in Illinois.

Who it's for

  • Adults focused on energy, mental clarity, and cellular repair
  • Patients who want injectable NAD+ rather than an IV visit

Your physician decides whether NAD+ Injection is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.83 mL (83 units) subcutaneously three times per week.

Cycle. Ongoing at your physician's direction; many patients use it a few times per week.
Ready for more? When you're ready for more, ask your physician to move you up to the next strength. Approved steps are charged at the price difference and applied to your next fill.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.

What's included

  • Licensed physician review of your intake, history, and labs
  • Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
  • Every batch independently tested before release
  • Sterile syringes and alcohol prep pads for injectables
  • Tracked delivery to your door, refills on schedule
  • Message your physician anytime; dose changes without an appointment

Storage & handling

  • Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
  • One vial is your monthly supply. A fresh vial ships to your Illinois address every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
  • Protect from light. Wipe the stopper with an alcohol pad before every draw.
  • Dispose of syringes in the sharps container per the included instructions.

What to expect

A typical course of NAD+ Injection in Illinois.

TimeframeWhat patients commonly report
Week 1Some patients notice an energy lift within the first few doses; flushing or nausea during injection is common and usually eases with slower administration.
Weeks 2–4Energy and focus changes tend to become more consistent.
OngoingLong-term treatment. Your physician adjusts the dose over time as your goals evolve.
Individual results vary. Compounded medications are not FDA-approved; a licensed physician determines whether treatment is appropriate and monitors your progress.

The science

How NAD+ Injection works, and what the research shows.

How it works

NAD+ injections deliver nicotinamide adenine dinucleotide directly into circulation, bypassing oral bioavailability issues.

NAD+ is essential for sirtuin activation, DNA repair, and cellular energy metabolism — all of which decline with age.

Clinical evidence

  • NAD+ levels decline significantly with age, falling 50-70% by the seventh decade.

    Massudi et al., PLOS ONE 2012
  • This decline is implicated in mitochondrial dysfunction, impaired DNA repair, and accelerated cellular senescence.

  • Yoshino et al. demonstrated that NMN supplementation restored mitochondrial function in aged mice.

    Cell Metab 2018
  • Direct NAD+ injection achieves substantially higher peak serum levels than oral precursors (NR, NMN) and bypasses first-pass metabolism.

  • Clinical studies are emerging, with ongoing trials in cardiovascular disease, neurodegeneration, and aging biomarkers.

  • NAD+ replacement is now considered a foundational longevity-medicine intervention.
