Why You're Always Tired and Foggy
(And How to Actually Fix It)
Your brain and body run on the same fuel. When that fuel runs low, everything suffers — energy, focus, memory, mood.
Razor-Sharp Focus
Alpha GPC and Huperzine A boost acetylcholine — the neurotransmitter behind focus, learning, and memory. Think clearly for hours, not minutes.
No More Afternoon Crashes
Sustained energy from morning to evening. No 2pm wall. No jitters. Just consistent output that lasts all day.
Natural. No Additives.
Every ingredient in Circuit Neural Performance is high-quality and natural. No fillers, no proprietary blends, no compromises.
Fixes the Root Cause
Circuit NMN boosts NAD+ at the cellular level — the molecule your mitochondria need to produce energy. Not a band-aid. An actual fix.
Works in 1-2 Weeks
Most users notice improvements in mental clarity and energy within 7-14 days of consistent daily use.
Wake Up Actually Rested
Better cellular energy and neurotransmitter balance means better sleep quality. You'll wake up feeling like yourself again.
Sound Familiar?
You're exhausted by 2pm every single day
You can't focus for more than 20 minutes
You sleep 8 hours but wake up tired
Brain fog makes work feel impossible
You've tried everything — more coffee, energy drinks, vitamins, better sleep. Nothing works for more than an hour.
Here's Why →The Real Reason You're Foggy and Tired
It's not stress. It's not laziness. Your brain is running low on the raw materials it needs to function.
Acetylcholine drives your focus, memory, and learning. Alpha GPC and Huperzine A in Circuit Neural Performance directly boost and preserve it — so your brain has the fuel to operate at full capacity.
L-Theanine and caffeine work together to deliver smooth, focused energy without jitters or crashes. Bacopa monnieri supports memory and learning over time. Phosphatidylserine keeps your brain cell membranes healthy and responsive.
And for the energy your body needs to keep up with your brain: Circuit NMN restores NAD+ at the cellular level — the molecule your mitochondria use to convert food into usable energy.
How Circuit Works
Simple to take. Powerful results. Three steps to feeling like yourself again.
Take Daily
One capsule of Neural Performance each morning. Two capsules of NMN each morning. With or without food. Consistency is everything.
Ingredients Activate
Alpha GPC, Huperzine A, and L-Theanine begin supporting neurotransmitter function. NMN converts to NAD+ and restores cellular energy production.
Feel the Difference
Within 1-2 weeks: sharper focus, no brain fog, no afternoon crashes, consistent energy all day.

Real People. Real Results.
No more brain fog — I'm stunned
"I've been taking Neural Performance for 3 weeks and the afternoon fog is completely gone. I used to re-read the same email five times. Now I'm sharp straight through to dinner."
Finally something that actually works
"Tried every focus supplement out there. Nothing came close until Circuit. The L-Theanine and caffeine combo is smooth — no jitters, just clear energy. I'm sharper at 4pm than I used to be at 10am."
I feel like myself again
"I forgot what it felt like to think clearly. Circuit brought it back. No jitters, no crash — just my brain working the way it used to before I turned 40."
My productivity has tripled
"The mental clarity from Neural Performance is on another level. I'm getting more done before lunch than I used to get done in a full day."
Worth every single penny
"I was spending $6/day on coffee that just gave me anxiety. Circuit costs less and actually solves the problem. My only regret is not finding this sooner."
Skeptical but converted
"Didn't believe the hype. Tried it anyway. Week 3 I realized I hadn't crashed once. Week 4 I came back for more. This is the only supplement I'll never skip."
Questions, Answered
They target different sides of the same problem. Neural Performance is formulated for cognitive function — focus, memory, mental clarity — using compounds like Alpha GPC, Bacopa monnieri, and Huperzine A that directly support brain chemistry. Circuit NMN works at the cellular level, restoring NAD+ so your mitochondria can produce energy efficiently. Together, they cover both your brain and your body.
Yes. Neural Performance contains caffeine paired with L-Theanine, which is clinically shown to smooth out caffeine's effects — giving you focused, jitter-free energy rather than a spike and crash. If you're sensitive to caffeine, start with one capsule and assess your tolerance.
For Neural Performance, most people notice sharper focus and mental clarity within 7-14 days of consistent daily use, with some feeling a difference in 3-5 days — ingredients like Bacopa monnieri build in effect over time. For NMN, cellular energy benefits typically become noticeable within 2-4 weeks as NAD+ levels are restored. Taken together, many customers report meaningful improvements in both brain and body within the first 2 weeks.
Yes — for both products. Every ingredient in Circuit Neural Performance and Circuit NMN is a high-quality, natural compound. No artificial additives, no fillers, no proprietary blends hiding weak doses. What's on the label is what's in the capsule.
Both Neural Performance and NMN are backed by our 60-day money-back guarantee. If you don't feel a noticeable difference after consistent use of either product, we'll refund every penny. No questions asked.
Neural Performance: take 1 capsule daily with 6-8 oz of water, preferably in the morning. NMN: take 1 capsule daily with water, ideally in the morning with food for best absorption. If taking both, they can be taken together at the same time. For best results, take at the same time each day. Consult your healthcare professional if you have any medical conditions.
Yes — they're designed to complement each other. Neural Performance supports cognitive function and brain chemistry; NMN supports cellular energy production by restoring NAD+. There are no known interactions between the two, and many customers take both daily for comprehensive mental and physical performance.
Each bottle of Neural Performance and each bottle of NMN contains 30 capsules. At the recommended dose of 1 capsule per day, each bottle lasts 30 days. If you're taking both, plan on one bottle of each per month.
