Made for people on peptides
Urolithin A + NMN + TMG
You are running a serious protocol, and your eyes are the first thing to complain.
You are running a serious protocol, and your eyes are the first thing to complain.
You dialed in your peptides. You track everything. You are doing the work most people never will.
And yet by the afternoon your eyes feel dry, strained, and slightly out of focus. The screen gets harder to read. Bright light feels harsher than it used to.
Here is what nobody flags for you: your peptides are asking your body to do more repair, more often. Repair costs energy. Your retina burns more energy per gram than almost any tissue you have. When the cellular power supply runs low, your eyes are where you feel it first.
It is not the screen. It is your mitochondria.
It is not the screen. It is your mitochondria.
Blue light and long hours are real, but they are not the whole story. Deep in every retinal and ocular cell sit your mitochondria, the tiny engines that turn fuel into the ATP your eyes need to focus, adapt to light, and stay comfortable. As NAD+ declines, those engines slow and the worn-out ones never get cleared. That is the strain. That is the blur. No pair of glasses fixes a power-supply problem.
The eye fatigue has a cause, and it is not just "too much screen time."
The eye fatigue has a cause, and it is not just "too much screen time."
You have quietly wondered if your eyes are just getting old. They are not giving out. Their supply of cellular energy is. When mitochondria decline, every high-demand tissue pays more to do the same job, and few tissues are as demanding as the retina. That is not aging you cannot touch. That is bioenergetics, and bioenergetics can be supported.
“A routine eye exam was never designed to see this. The retina is one of the most mitochondria-dense tissues in the body, and when cellular energy and NAD+ fall, ocular tissues are among the first to struggle. That is the layer most eye workups miss entirely.”
Two gummies. The full cellular-energy stack.
Two gummies. The full cellular-energy stack.
Precursor is two gummies a day. That is the whole ask. Inside is a clinical 500mg dose of Urolithin A plus 250mg NMN and 250mg TMG — the stack studied for restoring the cellular power your high-demand tissues, including your eyes, run on. No drops. No new device. No ritual you abandon by Thursday. You take them with your coffee. That is it.
Most Urolithin A products are quietly underdosed.

A lot of brands print Urolithin A on the label, then hide a tiny useless amount so they can charge less and still make the claim. You take it for a month, feel nothing, and decide the whole thing is a scam. You never actually tried it. The research is built on 500mg. Precursor gives you the full 500mg of Urolithin A, plus NMN and TMG to rebuild and protect NAD+, not a marketing dose.
What two weeks actually feels like.
What two weeks actually feels like.
This is not a jolt and your eyes will not suddenly feel wired. It is quieter and better than that. Around two weeks in, the late-day eye strain softens. Screens feel easier to sit in front of. You get to the end of a long day without that gritty, dragging tiredness behind your eyes you had stopped even noticing. It feels less like a fix and more like the floor under your visual stamina got raised.
“The retina is metabolically expensive tissue. Photoreceptors run on enormous mitochondrial output, and when cellular energy drops the eyes are one of the first places it shows. Urolithin A, NMN and TMG work upstream of any drop or lens, on the power those cells run on.”
The blur lifts, and your visual sharpness comes back.
The blur lifts, and your visual sharpness comes back.
The fuzzy, effortful focus is the part that worries people most on a protocol. Straining to read what used to be easy. Losing sharpness by evening. Your eyes are among the most energy-hungry tissues you have, and they suffer first when cellular energy drops. When fresh mitochondria come online and NAD+ is rebuilt, that visual clarity is usually one of the first things to steady. Focus comes back. The sharp version of your sight returns.
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 lets fresh, fully charged ones take their place. As you age and as your protocol demands more, that crew slows down. Urolithin A puts it back to work while NMN rebuilds the NAD+ that fuels ATP and TMG protects the methylation that keeps NMN working. Fresh engines, real energy — the part the screen-time conversation completely skips.
"I'm on a BPC-157 and MOTS-C protocol and my eyes were fried by 3pm every day. Three weeks on this and the late-day strain is genuinely gone."
"Blue-light glasses did nothing for the tired, gritty feeling. This is the only thing that actually touched it while I'm running my peptides."
"I stare at screens 10 hours a day on top of my protocol. My focus used to fall apart by evening. It holds now, all the way to dinner."
"Bright light and headlights at night were getting rough. Two months in, my eyes handle it the way they used to. Didn't change anything else."
Every month you wait, the energy deficit gets deeper.
Every month you wait, the energy deficit gets deeper.
It is tempting to file this under maybe later and keep pushing through the strain. But cellular decline does not pause while you decide, and your protocol keeps demanding energy your eyes have to help pay for. The longer worn-out mitochondria pile up, the harder your ocular tissues work for less return. Waiting is not neutral. It has a cost, and your eyes have been paying it.

You are tired of being sold the next thing that does not work, so do not take our word for it. Right now Precursor is up to 55% off with a 90 day money back guarantee. Take the gummies, run your protocol, notice how your eyes feel by 6pm, how screens sit, how light lands. If you do not feel the difference, you get your money back — feel it or send it back, even empty. No fight, no fine print.
The most-researched cellular stack since creatine.

Urolithin A, NMN and TMG are not a trend. The stack has been put through randomized, placebo-controlled human trials for what it does inside the cell, while most of the eye-care aisle 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 this cellular-energy stack on our radar.
“Your peptides send the signal. This stack makes sure the cell still has the power to act on it. For the eyes — some of the most energy-hungry tissue you have — that missing power is the whole story.”
“I spent years watching people on protocols push harder while their eyes strained and blurred. The cell is where it was hiding. That is exactly where Urolithin A, NMN and TMG work.”
“It is a rare stack with randomized human trials behind its core mechanism. That is the bar I want before I tell anyone something is worth their money.”

How It Works
I'm on a BPC-157 and MOTS-C protocol and my eyes were fried by 3pm every day. Three weeks on this and the late-day strain is genuinely gone.
Blue-light glasses did nothing for the tired, gritty feeling behind my eyes. This is the first thing that actually touched it while I'm running my peptides.
I stare at screens 10 hours a day on top of my protocol. My focus used to fall apart by evening. It holds now, all the way to dinner.
Headlights and bright light at night were getting rough. Two months in my eyes handle it the way they used to. Didn't change anything else.
For the first time in ages I got through a full workday without my eyes begging me to stop. That alone was worth it.
Dry, tired eyes every single evening no matter how many drops I used. This is the first thing that fixed the cause instead of the symptom.
My optometrist couldn't find anything wrong, but my eyes felt exhausted on my protocol. Turns out it was an energy problem, not an eye problem. Finally feel normal.
My night vision felt like it was slipping. Around week six things looked crisper and driving after dark stopped stressing me out.
I run GHK-Cu and a GLP-1 and everything felt like it was demanding more from my body. My eyes were the first to complain. Not anymore.
I'd accepted permanently tired eyes as the price of my protocol. It wasn't. I feel like my sight climbed back into gear.
Everyone told me to cut screen time. I already had. The difference here was real and it wasn't about the screens.
The eye drops masked the dryness for an hour. This actually reached whatever was causing it. Huge difference by week three.
I code all day and stack peptides for recovery. My eyes used to burn out by 2pm. Now they hold steady until I log off.
The late-afternoon blur used to flatten my focus. I haven't hit it in weeks. Not wired, just steady, which is all I wanted.
My partner noticed I'd stopped squinting at my phone every night. I hadn't even clocked how bad it had gotten.
I'd read every biohacking thread and wasted hundreds on eye supplements that did nothing. This one I'd actually repurchase.
Screen glare used to give me a headache behind the eyes by evening. That's basically gone now that my cells have fuel again.
Not a miracle, and I like that they don't pretend it is. But week by week my eyes feel less taxed on my protocol.
The blur was the scariest part. Feeling visually sharp again has given me my confidence back at work.
I wish I'd found the cellular-energy angle two years ago. My eyes stopped being the weak link in my protocol.
Steady focus, comfortable on screens, and no more gritty evenings. Three things I'd given up on, quietly handled.
My eye exam was always "fine" while my eyes felt shot. Someone finally explained the energy side, and then it actually helped.
Light sensitivity had me reaching for sunglasses indoors. That's eased right off. I notice bright rooms don't bother me now.
I'm deep into a peptide protocol and my eyes finally feel like they can keep up with it. Worth more than I paid.
“Willpower does not refuel a cell. Pushing through tired eyes just draws the energy deficit deeper.”
Pushing through works right up until it doesn't. It gets you to the end of the day, but it does nothing for the cellular power your eyes are running short on — which is why the strain keeps coming back harder. Peppy works one layer deeper, on the energy those ocular cells run on. The two are not the same thing.
“Each one manages a symptom. None of them reaches the cell underneath it.”
You tried the blue-light glasses for the screens, the drops for the dryness, the whole drawer. Each one works on one symptom on the surface. None of them reaches the mitochondria that power your eyes in the first place. Peppy is that missing layer, the one place the surface fixes never went.
“You stacked more signal onto cells that were already short on the energy to act on it.”
When your eyes still felt off, the instinct was to add more peptides. Sometimes more signal helps. But peptides drive repair, and repair costs energy — when the cellular power supply is low, the signal outruns what the cell can actually do. Peppy rebuilds the power underneath so your protocol has something to execute with. Always run any change to your protocol past your doctor first.

Is this going to interfere with my peptide protocol?
No. Urolithin A, NMN and TMG are not peptides and don't compete with yours. They work one layer deeper, restoring the cellular energy and NAD+ your body needs to actually execute the repair your peptides are signaling for — which is exactly what energy-hungry tissue like your eyes relies on. Safe to run alongside a protocol, but check with your prescribing doctor first.
I've tried glasses and drops and my eyes still feel tired.
Then you already proved the most important thing. The blue-light glasses, the drops, pushing through — each managed a symptom on the surface. None of them reached the mitochondria that power your eyes. This is that missing layer, and it is the one place the others never went.
How long until I notice a difference in my eyes?
The stack works at the cellular level, so it builds gradually over several weeks of daily use. 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 is a well-studied compound your body normally produces from foods like pomegranates and walnuts, and NMN and TMG are well-researched cellular-energy nutrients, all 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 Urolithin A, 250mg NMN and 250mg 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.
