The ingredient behind the ambition
You bring the ambition.
Creatine helps fuel the effort.
Strength. Muscle. A daily habit worth building.
Training. Nutrition. Consistency.
Built one day at a time.
Creatine helps replenish ATP, your muscles’ quick-use energy. It supports repeated high-intensity efforts—the hard sets and explosive bursts that make demanding training count.
ESTABLISHED ADULT PERFORMANCE RESEARCHCreatine paired with resistance training can support greater strength and lean mass gains than training alone. A 2024 adult review found an average additional 1.14 kg of lean mass.
*ADULTS UNDER 50. LEAN MASS INCLUDES WATER, NOT JUST MUSCLE. RESULTS VARY.Your brain uses creatine, too. A review of 16 adult trials found a benefit for memory. That makes cognition an exciting research direction, with more to learn before promising broader brain-health benefits.
EMERGING ADULT RESEARCH / FINDINGS ARE MIXEDWhy MTRL belongs in the conversation
Two soft chews. One grab-and-go packet. Dessert-inspired flavor. We’re building the routine around convenience, creatine stability and a dose we commit to verifying by batch.
Meet your next daily ritualCreatine helps replenish ATP, which fuels short, intense efforts. Research supports improvements in repeated high-intensity performance, strength and muscle gains when combined with resistance training in adults.
Explore the NIH evidenceA 2024 meta-analysis in adults under 50 found creatine plus resistance training increased lean body mass by 1.14 kg more, on average, than resistance training alone. Lean mass includes water; it does not measure muscle alone. Results vary.
Read the meta-analysisA 2024 review of 16 randomized trials found a benefit for memory, with mixed findings across other cognitive measures. This is emerging adult research, not a promise of better focus or brain health.
Explore the cognitive researchThese are ingredient findings, not clinical results for MTRL. Effects vary with training, population and study protocol. Adult findings should not be assumed to apply to teens. MTRL’s final formula and serving directions remain in development.

Form matters / Why we chose a chew
The gummy headlines raised the right question: how much creatine is actually left in the product?
creatine gummy products sampled by SuppCo failed identity and potency testing.
Read the original testing reportA limited sample, not a finding about every gummy. Two gummy products passed.WIRED reported the potency shortfalls and the formulation challenges behind creatine gummies in June 2025.
Read the coverageCreatine can convert to creatinine in solution. In the pH range common to acidic foods, more acidity can accelerate that conversion.
Water content and water activity are different. The water available in a formula helps determine how creatine behaves during storage.
Temperature and time influence degradation. A result on day one does not establish the dose at the end of shelf life.
The MTRL response
We chose a soft-chew platform to develop around creatine stability. Our priorities: manage available water, pH and processing conditions, then protect the finished chew in its daily packet.
A delicious chew should come with a dose you can trust. Our commitment: verify every finished batch, study the dose over time and publish the results. Choose your flavor. Expect the proof. Testing is being finalized before launch.

Made for the everyday athlete
The early starts. The last rep. The decision to show up again.
MTRL is being built to fit into that life.
The MTRL standard
“Third-party tested” should lead somewhere. Our commitment is to publish independent potency results by batch and show how the finished product holds up over time.
Independent potency testing on every finished production batch. Measure what’s in the serving, rather than relying on the amount added.
Stability studies in the final daily packet. Publish study conditions, time points and results so shelf-life evidence can be understood.
Public reports tied to the batch on your pouch. Clear potency results and accessible stability data are the standard we commit to.
We have selected Eurofins for our planned potency and stability program. Eurofins offers finished-product and shelf-life testing, and has published technical guidance on validated creatine and creatinine analysis.
Explore Eurofins’ testing capabilitiesBatch reports and stability results will be published as they become available. Laboratory scope and study design are being finalized; no completed MTRL test reports are available yet.
Laboratory selection is a MTRL decision. It does not represent Eurofins endorsement, certification or completed testing.
For adults on a GLP-1 journey
Build the conversation around more than the scale.
Weight loss can include lean tissue. If you’re using a GLP-1 medication, protecting your strength deserves a place in your plan: resistance training, enough protein and nutrition that supports your goals.
Creatine supports resistance-training gains in adults generally. Our vision for MTRL is to make that daily routine easier to keep—two soft chews, one portable packet, flavors you look forward to.
Make room for your next routineCreatine has not been proven to prevent muscle loss specifically during GLP-1 treatment. Discuss your plan with your clinician. Read the 2025 joint professional advisory and the evidence review.
For parents of teen athletes
They put in the work.
You ask what’s behind the label.
From a father and founder
I’m a father before I’m a founder. MTRL began with my mission to find reliable, trusted products for my son Knox.
When your child is putting in the work, you want to feel confident about what supports his routine. What’s really in a serving? Does that amount hold up over time? Can a parent see the evidence, rather than just a promise on the front of a pouch?
I wanted a product that could earn my trust and fit into real life: a convenient packet, flavors worth looking forward to and a testing standard parents could understand. That is what we are building with MTRL—thoughtful formulation, independent testing and a commitment to publish results by batch.
Knox is part of why we began. The mission extends to every athlete building a routine and every parent asking the right questions. Trust should be something you can verify.
Better MTRL. Better build.
Built on a father’s standard of trust.
Creatine research is strongest in adults. Adolescent studies are smaller and long-term evidence is limited. For athletes under 18, make supplement decisions with a parent or guardian and a qualified healthcare professional. Read the adolescent research review.
