How the kit works
Measure. Understand. Optimize.
Your night-time erections happen while you sleep, so most men never see them. The Starter Kit closes the loop: measure them at night, understand them in the morning, and support the blood flow behind them.†
Measure
The Adam Sensor records your night-time erections while you sleep: how many, how long and their quality.
Understand
The Adam app turns each night into results and your AndroAge™ score, so you can follow your trend.
Optimize
One scoop of NightNOX™ before bed supports nitric oxide and the blood flow behind your erections.†
Repeat
Every night you measure adds to the picture, so you see the direction you’re heading, not just one night.
Born in the clinic
For the last 12 years we’ve run men’s health clinics. The Starter Kit brings the same three steps home.
AndroAge™ score in the animation is an example. NightNOX™ is a dietary supplement, not a medicine. The Adam Sensor is a general wellness device.
01 · Measure
Why night-time erections matter
erections every night, while you sleep - your body’s built-in maintenance routine.
Your body’s natural night gym
Each episode sends oxygen-rich blood into the erectile tissue, keeping it flexible, nourished and healthy — like a nightly workout that protects function for the long term. Just as your daily steps reflect physical activity, the total duration of your night-time erections reflects how well your body is maintaining itself at rest. Longer total duration means better oxygenation, tissue health and recovery.
A key indicator of male longevity & wellness
Night-time erections are more than a measure of performance; they are one of the most powerful functional biomarkers of men’s health. They depend on your cardiovascular system, hormones, nerves and sleep quality. Changes in night-time erections often mirror early shifts in heart, metabolic or hormonal health long before symptoms appear. Through the Adam App this is translated into your AndroAge™ — a single score, expressed in years, that reflects how well your body is functioning across these systems.

Why before bed?
Your body does its repair work while you sleep, and repair runs on blood flow.
Most nitric oxide products are pre-workout powders built around a pump that is gone by dinner. NightNOX™ is built for the eight hours that actually matter - and it is stimulant-free, so it will not keep you up.†

What do the experts say?
Night-time erections are a little-known yet crucial biomarker of sexual function, as well as cardiovascular, hormonal, and lifestyle health. The Adam Sensor, a revolutionary technology once confined to sleep labs, now puts this insight in any man’s hands.
— Dr Ben DavisMen's Health Doctor and Clinical Sexologist
The Adam sensor represents an important step forward in proactive men’s health. By transforming nocturnal erections into objective, longitudinal data, the platform gives men valuable insight into a key marker of sexual and overall health. I strongly support tools that encourage earlier engagement, meaningful tracking, and greater ownership of long-term health and performance.
— Michael StrømMen’s Health Specialist and International Shockwave Educator
Tracking night-time erections is one of the single best indicators of a man’s overall health and wellbeing.
— Professor Amr RaheemConsultant Andrologist & Professor of Men’s Health
Healthy erections are built while you sleep. The Adam Sensor proves it, showing which habits boost or blunt night time erections and long-term function. Its data drives the research and protocols I share with my men’s-health communities, because data beats marketing.

FAQs
What’s in the Adam Starter Kit?
The Adam Sensor, lifetime access to the Adam app, and your first month of NightNOX™ (one tub, 30 servings).
How does billing work?
$275 today covers the Adam Sensor and your first month of NightNOX™. NightNOX™ then renews at $59 a month, starting one month after your order, until you pause or cancel. The Sensor is a one-off purchase.
Can I cancel?
Yes. Pause or cancel your NightNOX™ subscription anytime in your account. You keep the Sensor and the app.
How does the Sensor feel while I sleep?
The Adam Sensor is non-constrictive. Its flexible, adjustable pull-out section adapts to your size and sits securely without applying pressure, so most men don’t notice it once they’re asleep. If it doesn’t fit, we give you a full refund.
How is the Adam Sensor different from a penis ring?
Most consumer rings, even ones sold as trackers, are constriction devices, and safety guidelines generally recommend not wearing those for more than 30 minutes. The Adam Sensor is designed for sleep: a flexible, adjustable band that doesn’t restrict blood flow or natural movement.
How often should I wear the Sensor?
Wear it for three nights when you start to set your baseline. After that, once a week or every couple of weeks is enough to follow your trend. Some men like to wear it nightly.
What is NightNOX™ and when do I take it?
NightNOX™ is a stimulant-free nitric oxide and blood flow support formula: nine active ingredients in one mixed-berry scoop.† Mix one scoop in water and drink it 30 to 60 minutes before bed.
Can I take NightNOX™ with medication?
If you take medication for blood pressure or erectile function, or you have a medical condition, ask your doctor before starting. Nitric oxide affects blood vessels, and so do several common medicines.
How is my data used?
Your data is encrypted and used to give you your insights in the app. We don’t sell your personal health information to third parties, insurance companies or advertisers.
Is the Adam Sensor a medical device?
No. The Adam Sensor is a general wellness device. AndroAge™ is an estimate from night-time erection patterns, not a diagnosis.
