Get more out of every session
You bring the effort. We bring the science. Momentous Pre-Workout combines research-aligned ingredients to support sustained energy, sharp focus, strength, and endurance.*
A Pre-Workout you can feel good about putting in your body.
Sharp Focus & Steady Energy
150mg caffeine supports alertness, while 300mg L-Theanine activates attentional pathways. Together, their effect is focused attention without overstimulation, so you can stay locked in on the work ahead.
Performance Boost
Clinically-dosed 6g L-citrulline & 2.5g betaine support blood flow, muscular endurance, and strength to help you handle more intensity, for longer.
Train With Your Brain
Training is mental work too. 300mg Alpha-GPC, in a clinically dosed amount, supports focus and cognitive performance. 1g L-tyrosine is a building block for dopamine and norepinephrine, both involved in attention.
Trust That’s Verified
Every ingredient and its dose is listed on the label. No proprietary blends. Nothing artificial. NSF Certified for Sport® and independently third-party tested to give you unmatched confidence in what you’re taking.
What a Pre-Workout is Actually Doing
A pre-workout isn't one ingredient doing one job. Here's what's inside, and what it's there for. Key ingredients are dosed to align with clinical research:
- L-Citrulline, 6g — for blood flow and exercise tolerance
Unlike oral arginine, it largely bypasses breakdown in the gut and liver, helping raise arginine levels in your blood. - Betaine, 2.5g — for muscular strength
It helps muscle cells hold water and plays a role in energy production. - L-Theanine + Caffeine, 300mg + 150mg — for focused energy
Caffeine works on tiredness, L-theanine on attention. Together, at a measured 2:1 ratio, they support alertness with focused attention. The caffeine comes from green tea leaf extract. - Alpha-GPC, 300mg — for cognitive support
A source of choline your body uses to make acetylcholine, a neurotransmitter involved in attention. In one study, a single 315mg dose improved cognitive performance in resistance-trained men within the same session. - L-Tyrosine, 1g — for attention
A building block for dopamine and norepinephrine, both involved in attention. Research suggests it may help support cognitive function under acute stress or mental demand. - Magnesium (50mg), Sodium (75mg) + Potassium (80mg) — for muscle function
Sodium and potassium help maintain the electrical gradients that let nerve impulses travel and muscles contract. Magnesium supports normal neuromuscular function and the ATP-dependent processes behind energy production. They're included to complement the formula, not to replace electrolytes or serve as a standalone hydration solution.
- Mix 1-2 scoops with 8-12oz of cold water. Drink 20–30 minutes before training.
- The 20–30 minute window aligns with caffeine’s onset of action. By the time you start your first working set, the caffeine is active, the theanine is tempering it, and the citrulline and betaine are available in your bloodstream.
- For best results, drink your entire serving of Pre-Workout within 5-10 minutes (rather than slowly sipping it over a longer period of time).
Important timing note: Avoid taking Pre-Workout within 6 hours of bedtime. The 150mg of caffeine has a half-life of roughly 5–6 hours in most people, and late-day dosing can impair sleep quality even if you don’t feel “wired.”
Best practice: Avoid taking Pre-Workout at the same time as collagen, a multivitamin, iron, or calcium supplements, as these can interfere with absorption of certain ingredients. Give at least 1 hour between them.
Lemonade: 6g L-citrulline, 2.5g betaine anhydrous, 1g L-tyrosine, 300mg L-theanine, 300mg Alpha-GPC, 150mg caffeine (from green tea leaf extract), 80mg potassium (as potassium citrate), 75mg sodium (as sodium chloride), and 50mg magnesium (as dimagnesium malate, Albion®) per serving.

Momentous Pre-Workout is designed to be taken 30 minutes before training, so it's working with you by the time you start your session. The benefits of Pre-Workout are noticeable on the first use:
- Steady energy without chasing a maximum stimulant dose
- More in the tank when training asks more of you
- Sharper focus and mental clarity going into a session
Consistency matters. Pre-Workout is built to earn a repeated place in your routine rather than to be saved for the heaviest day on the calendar. Much of the research behind these ingredients reflects consistent use over time, so the benefit compounds when it becomes part of how you train.
There are 8 credible reviews and studies related to this product:
1. l-Citrulline supplementation improves O2 uptake kinetics and high-intensity exercise performance in humans
"In a 10-person crossover RCT, citrulline improved oxygen-uptake kinetics, improved exercise performance, extended tolerance to severe-intensity exercise, and modestly lowered blood pressure vs. placebo (Bailey et al., 2015, Journal of Applied Physiology)."
"In a 30-person crossover RCT citrulline (6 g) and alpha-GPC (300 mg) increased 20 km time-trial peak power by 11% and time-to-fatigue by 36% vs. placebo in trained cyclists (Harrington, 2023, Journal of the International Society of Sports Nutrition)."
"In a 10-person crossover RCT young athletes increased muscular-endurance reps and lowered post-exercise cortisol and lactate vs. placebo (Arazi et al., 2022, Journal of the International Society of Sports Nutrition)."
"Pooling 17 studies (n = 317), chronic betaine supplementation (≥7 days) increased maximal strength (SMD 0.47), with the largest effect in lower-body lifts (Zawieja et al., 2024, Journal of Sports Sciences)."
5. Acute Alpha-Glycerylphosphorylcholine Supplementation Enhances Cognitive Performance in Healthy Men
"In a 20-person crossover RCT, a single 315 mg dose of alpha-GPC improved Stroop-test cognitive performance in resistance-trained men within the same session (Kerksick, 2024, Nutrients)."
"In a crossover RCT theanine plus caffeine improved attention-switching performance vs. placebo (Einother et al., 2010, Appetite)."
7. Effect of Green Tea Phytochemicals on Mood and Cognition
"Reviewing 49 studies spanning 12–250 mg of theanine combined with caffeine, the combination consistently improved sustained attention while blunting caffeine's overarousal effect (Dietz & Dekker, 2017, Current Pharmaceutical Design)."

Momentous Pre-Workout is designed for active adults who want to support both physical performance and mental focus during training, without relying on excessive stimulants. Whether you're strength training, performing high-intensity intervals, or preparing for a demanding workout, the formula combines research-backed ingredients for energy, focus, and physical performance. It's especially well suited to people who value transparent dosing, third-party testing, and an intentional approach to supplementation.
You may begin noticing the effects of caffeine within 15–45 minutes, with alertness typically increasing during the first hour. Other ingredients work differently. For example, betaine has been studied for potential strength benefits with repeated supplementation over at least seven days. Your experience will depend on factors including caffeine sensitivity, training intensity, and individual response.
For most people, taking Momentous Pre-Workout approximately 20–30 minutes before training is a practical starting point. This allows time for the caffeine and other ingredients to begin taking effect. Mix one serving with water according to the package directions, and consider your personal caffeine tolerance and workout schedule.
Momentous Pre-Workout is formulated with a moderate 150mg of caffeine, rather than relying on a high stimulant dose.
