Precursor Gummies™
Urolithin A, NMN, and TMG at clinical doses — the mitochondrial precursor stack built for peptide users. Your peptides send the signal. This is the cellular layer that lets your body execute it.
Your peptides are only half the equation.
- Your peptides send the signal. BPC-157, MOTS-C, GHK-Cu — every peptide works by telling your cells to do something. Repair this. Build that. But a signal is only as good as the cell's ability to act on it.
- Acting on it costs energy. Every repair and adaptation your peptides trigger runs on ATP. And ATP cannot be produced without NAD+. No NAD+, no execution — the signal arrives and nothing happens.
- Your NAD+ is running low. By age 50, NAD+ has fallen roughly 50%. By 70, it is down 80%. You are paying for a full peptide protocol but running it on a depleted power supply.
- Precursors restore the power supply. Urolithin A clears the damaged mitochondria. NMN rebuilds NAD+. TMG protects the methylation pathway NMN draws from. Three compounds, three bottlenecks, one gummy.
- Now your protocol executes. Same peptides. Same dose. A cellular environment that can finally act on the signal. This is the layer most peptide users are missing.
Three compounds. One daily gummy. The three most clinically validated mitochondrial precursors — dosed for synergy, not for a label.
Urolithin A — 500mg
Triggers mitophagy: your cells identify damaged mitochondria, break them down, and build fresh, efficient ones. Only about four in ten adults produce a useful amount on their own. We dose it directly, at the clinical 500mg.
NMN — 250mg
The most direct precursor to NAD+, the molecule every cell uses to turn fuel into ATP. NAD+ falls roughly 50% between age 20 and 50. NMN rebuilds it — measurably, within weeks.
TMG — 250mg
The methyl donor that keeps NMN safe long-term. NMN burns through methyl groups as it converts to NAD+; without TMG, homocysteine climbs. Most NMN products skip it. We don't — because the research is clear they work together or not at all.
Four numbers from human trials.
Every number below comes from randomized, placebo-controlled human trials, published in peer-reviewed journals. Not animal studies. Not in-vitro. Real people.
Muscle strength
Clinical resultParticipants on the clinical Urolithin A dose gained 12% in muscle strength — with no change to training, diet, or exercise habits.
Peak VO2 (endurance)
Clinical resultYour endurance ceiling is mitochondrial, not pulmonary. Peak VO2 rose 19% on the clinical dose.
CRP (inflammation marker)
Clinical resultC-reactive protein, the standard systemic-inflammation marker, fell 22%. Less inflammation means resources go to repair instead of firefighting.
Mitochondrial function
Clinical resultMarkers of mitochondrial function more than doubled — the engine every peptide signal depends on.

Your protocol, with Precursor.
What the precursor layer adds to a peptide protocol. The peptides signal it. The precursors execute it.
What to expect with Precursor
25+ human clinical trials · 2,200+ participants · honest pacing
Two gummies. Every morning. That's the protocol.
Two gummies, every morning
500mg Urolithin A, 250mg NMN, 250mg TMG. With or without food, alongside your peptide protocol. The simplest part of your day.
Daily, consistently
Precursors work by restoring a baseline. The effect builds with consistency — and one gummy makes that effortless. No three-bottle juggling.
Around month two
Most customers say recovery and energy shift first — usually between week 3 and month 2 — then strength and endurance follow.
I'd been running BPC-157 for over a year and figured I'd hit my ceiling. Eight weeks after adding Precursor, recovery between sessions was on another level. The peptides were finally landing.— Marcus T., verified customer · on peptides 2 years
Real peptide users. Real protocols.
Recovery is finally keeping up.
Two years on BPC-157 and something always felt missing. Three weeks on Precursor and my recovery between sessions is noticeably faster. The protocol is finally working the way it should.
Finally, NMN done right.
I stacked NMN solo for a year and my homocysteine kept creeping up at every checkup. Switched to Precursor — UA, NMN and TMG together — and my labs are back in range.
Bought for the science.
I read every trial before buying. JAMA, Nature, Cell Reports. The data is real, and now I can feel what the data showed. Month three and my endurance is fundamentally different.
Outperforming guys half my age.
CrossFit four days a week. Since adding Precursor my Fran time dropped 40 seconds and I'm not wrecked the next day. Something is different at the cellular level.
Stacking with MOTS-C.
Added Precursor to my BPC-157 and MOTS-C cycle. How fast my tendons recover now is night and day. My physical therapist noticed before I told her what I'd changed.
Sleep improved too.
Unexpected bonus — my sleep quality jumped around week 3. Deeper sleep, better HRV scores on my Whoop. Mitochondrial health clearly reaches past muscle.
Stronger at 52 than at 45.
Seven months on the stack. Deadlift up 30lbs, inflammation markers the lowest in a decade, and I recover from heavy sessions in half the time.
Honest, full-dose formula.
Read the label before I bought. Clinical doses, no proprietary-blend games, no tiny sprinkles. That's what made me trust it.
Run it for 90 days. If you don't feel it, we refund you.
Take Precursor daily for three months alongside your protocol. If you don't feel a measurable difference in recovery, energy, or output, send the bag back — even empty — and we'll refund every cent. We carry the risk so you don't have to.
The longer you run it, the more it compounds.
Precursors work by restoring a baseline — staying on is the whole point. Most customers run 2 or 3 bags.
