Made for people who want to feel younger
500mg Urolithin A
You are doing everything right and still feel older than you should.
You are doing everything right and still feel older than you should.
The sleep, the training, the protein, the supplements. You are doing the work most people over 40 never will.
And yet some weeks you feel scraped out. Flat by mid-afternoon. Recovery drags. A low-grade tired feeling you can’t quite name.
Here is what nobody tells you about aging: it is not really about willpower. Every cell in your body has a power supply, and that supply quietly declines with age — and when it does, feeling older is exactly what you get.
It is not you getting lazy. It is your cellular power supply.
It is not you getting lazy. It is your cellular power supply.
Aging raises the demand on your body while quietly cutting the supply. Deep in every cell sit your mitochondria, the tiny engines that turn fuel and oxygen into ATP — the actual energy your muscles, brain, and recovery run on. They run on NAD+, and NAD+ can drop by as much as 50% between your 20s and 50s. Worn-out mitochondria pile up while NAD+ runs low, and the cellular power supply can’t keep pace. That gap is what feeling older actually is.
The tired feeling has a name, and it is not weakness.
The tired feeling has a name, and it is not weakness.
You have quietly wondered if you just can’t keep up anymore. You can. Your effort never dropped — your supply of cellular energy did. When NAD+ falls and tired mitochondria stack up, every day costs more to power. That is not a discipline problem. That is bioenergetics, and bioenergetics can be rebuilt.
“Aging isn’t just time passing — it’s your cells’ power supply quietly declining. NAD+ can drop by half between your 20s and 50s. Most people chase symptoms without ever touching the energy layer underneath them, which is where real change happens.”
Two gummies. A clinical stack of Urolithin A, NMN and TMG.

Precursor is two gummies a day. That is the whole ask. Inside is a clinical 500mg dose of Urolithin A plus NMN and TMG — the stack built to rebuild the cellular power supply that quietly declines with age. Urolithin A clears worn-out mitochondria, NMN rebuilds NAD+, TMG protects the methylation that keeps NMN working. No new ritual. You take them with your coffee.
Most cellular-energy products are quietly underdosed.

A lot of brands print Urolithin A or NMN on the label, then hide a tiny amount so they can charge less and still make the claim. You take it for a month, feel nothing, and write the whole category off. You never actually tried it. The research is built on a real 500mg dose of Urolithin A. Precursor gives you the full clinical dose alongside NMN and TMG, not a marketing sprinkle.
What two weeks actually feels like.
What two weeks actually feels like.
This is not a jolt and you will not feel wired. It is quieter and better than that. Around two weeks in, the afternoon dip softens. You come out of a long day without feeling wrecked. You realize you got through the whole day without the heavy, dragging tired feeling you had started treating as normal. It feels less like a stimulant and more like the floor under you got raised.
“Recovery gets metabolically expensive as we age. Repairing tissue and clearing inflammation both run on ATP, and ATP runs on NAD+ and healthy mitochondria. When that cellular power supply thins out with age, recovery is one of the first things to slow. Rebuilding that supply works upstream of any single symptom of aging.”
Steadier energy, and the mental fog lifts.
Steadier energy, and the mental fog lifts.
The part people notice first is the fog and the flatness. Your brain is the most energy-hungry organ you have, and it feels a stretched cellular power supply before anything else does. When NAD+ climbs back up and fresh mitochondria come online, the heavy tired feeling is usually the first thing to ease. Steadier energy. A clearer head. You feel like yourself again, not just older.
Mitophagy, in plain English.
Mitophagy, in plain English.
Mitophagy is your body’s cleanup crew for cells. It clears out the dead, worn-out mitochondria clogging your system and makes room for fresh, fully charged ones. That cleanup crew slows down with age. Urolithin A puts it back to work while NMN rebuilds the NAD+ that fuels the new engines. Fresh mitochondria, real energy — the layer aging alone never lets you rebuild on your own.
"I'm 44 and I was dragging every afternoon and couldn't figure out why. Three weeks on these and the tired feeling lifted. I finally feel like myself again."
"My bloodwork was fine and I was still gassed all the time. This is the only thing that actually touched the fatigue that came with getting older."
"Recovery between workouts used to take days. Since adding these I bounce back like I did in my 30s."
"I train hard and I'd gone flat anyway. After two months my steady energy genuinely came back without changing anything else."
Every year you wait, the deficit gets deeper.
Every year you wait, the deficit gets deeper.
It is tempting to file this under later and keep telling yourself feeling tired is just part of getting older. But the decline does not pause while you decide. The longer NAD+ stays low and worn-out mitochondria pile up, the harder your body works for less return. Waiting is not neutral. It has a cost, and you have been feeling it.

Urolithin A, NMN and TMG are not a trend. Together they have been put through randomized, placebo-controlled human trials for what they do inside the cell, while most of what gets marketed for aging has been put through none.
When everything else is a maybe, take the studied one.

Experts
Why we built itThe researchers and clinicians who put the Urolithin A, NMN and TMG stack on our radar.
“NAD+ can decline by up to 50% between your 20s and 50s. Urolithin A, NMN and TMG make sure your cells still have the power to keep up with the life you want to live, at any age.”
“I spent years watching people over 40 chase symptoms of aging while their labs looked fine. The gap was in the cell — a depleted NAD+ pool and tired mitochondria. That is exactly where this stack works.”
“These are the rare compounds with randomized human trials behind their core mechanism. That is the bar I want before I tell anyone something is worth their money.”

How It Works
I'm 44 and I was dragging every afternoon and couldn't figure out why. Three weeks on this and the tired feeling lifted. I finally feel like myself again.
My bloodwork was fine and I was still gassed all the time. This is the only thing that touched the fatigue that came with getting older.
I used to feel wrecked for two days after every hard session. My recovery is finally keeping up with the work I'm putting in.
I train hard and I'd gone flat anyway. Nothing helped. After two months my steady energy genuinely came back without changing a thing.
For the first time in years I got through a full week without that heavy tired feeling. Just steady.
Wired but exhausted every night since I ramped up. I'd tried more caffeine, pre-workout, all of it. This is the first thing that let my energy actually stabilize.
My doctor kept saying my labs looked great while I felt run-down constantly. Turns out it was the cellular side. I finally feel like myself on my protocol.
Recovery had gone to garbage no matter how much I slept. Around week six I started bouncing back between sessions again. My training partners noticed.
I used to get run into the ground by a heavy training block on my protocol. This block I didn't. I feel resilient again.
I felt run-down in my own body, like the tank was always half empty. It's filling back up, slowly, and I didn't think it would.
Everyone kept telling me to just rest more. I already was. The difference here was real and it wasn't willpower.
The peptides did their thing but the fatigue stayed brutal. This filled the gap the protocol never reached.
I'm a runner and my protocol had me too gassed to log real miles. My stamina is finally climbing back instead of sliding.
The 3pm wall used to flatten me on protocol days. I haven't hit it in weeks. I'm not buzzing, I'm just steady, which is all I wanted.
My wife kept asking when I'd stop being so wiped out. Last week she said I seemed like myself again. That's the whole review.
I'd read every Reddit thread and spent hundreds on recovery stacks that did nothing. I was a skeptic. This one I'd actually repurchase.
Sleep went to pieces when I ramped up my protocol. I'm finally waking up rested instead of like I never slept.
Not a miracle, and I like that they don't pretend it is. But week by week I feel steadier and less run-down on my protocol.
The mental fog was the worst part of feeling run-down. Feeling sharp again has given me my edge back at work.
I'd accepted that feeling drained was just the cost of the protocol. It wasn't. I wish I'd found the cellular angle a year ago.
Steady energy, clearer head, and I'm recovering. Three things I'd given up on while grinding my protocol, quietly handled.
My labs were always "fine" while I felt drained. Someone finally explained why, and then actually helped.
I felt flat, like my drive had been turned down under the protocol. It's come back up. I've got my energy again.
I'm 53 and running a protocol, and I feel like I climbed back into my own body. That's worth more than I paid.
“Grinding through a tired stretch doesn’t rebuild the cellular power supply it comes from. It just spends more of it.”
Pushing through is a skill, and as you age you’ll need it more. But willpower spends cellular energy, it doesn’t rebuild it. That is why you can grind through a week and still feel more run-down at the end of it. Peppy works one layer deeper — rebuilding the NAD+ and mitochondria that the grind runs on. The two sit together.
“Stimulants borrow energy against tomorrow. They never rebuild the cellular supply that age quietly drains.”
You reached for another coffee, the pre-workout, the energy drink. Each one whips a tired cell to work harder for a few hours, then leaves you flatter. None of them rebuilds the NAD+ or the mitochondria that decline with age. Peppy is that missing layer — the one place the stimulants never went.
“A cabinet of one-off supplements still misses the cellular power supply underneath all of them.”
When energy lagged you built a stack — the electrolytes, the greens, the sleep aids, the magnesium. Each one nudges a single piece. None of them reaches the NAD+ and mitochondria that drive energy across your whole body as you age. Peppy rebuilds the power underneath the stack.
Two Gummies Daily.
The Clinical Dose.
Worth More Than You Pay.
Will this interfere with any medications or supplements I'm already taking?
No. Precursor works one layer deeper — rebuilding the NAD+ and mitochondrial function your cells run on. It is built to work alongside your existing routine, but always run any new addition past your doctor first.
I've tried everything to feel less tired and nothing worked.
Then you already proved the most important thing. More caffeine, the pre-workout, the random supplement stack — each one masked a symptom or borrowed energy against tomorrow. None of them rebuilt the cellular power supply that declines with age. This is that missing layer, and it is the one place the others never went.
How long until I notice a difference?
The stack works at the cellular level, so it builds gradually over several weeks of daily use as NAD+ rebuilds and worn-out mitochondria get cleared. Everyone responds differently and results are not guaranteed, which is why every first order is backed by the 90-day money-back guarantee.
Is this stack safe?
Urolithin A, NMN and TMG are well-studied compounds — Urolithin A is one your body normally makes from foods like pomegranates and walnuts — made here in a third-party-tested facility. If you are pregnant, nursing, or on medication, check with your doctor first.
How many gummies, and what's the dose?
Two gummies a day deliver 500mg of Urolithin A plus NMN and TMG, the amounts used in published research. A full pouch is a 30-day supply.
Can I cancel easily? What if I don't feel anything?
Yes. Pause or cancel anytime in a couple of taps. Cellular support can be quiet at first, so give it a fair, consistent run, and if you are not feeling the difference the 90-day money-back guarantee makes it right — feel it or send it back, even empty.
