cutting-edge ingredients to unleash your potential
ElevATP® (150mg)
ElevATP is a natural combination of ancient peat and apple polyphenols clinically shown to increase levels of adenosine triphosphate (ATP), the energy currency of the body, and support improved strength, power, and performance.
Since ATP is the source of energy for use and storage at the cellular level, the more you can elevate your ATP levels prior to exercise, the better you’ll perform.
In research, ElevATP has been clinically shown to…
- Improve Lean Muscle and Strength, and Training volume
- 64% Increase in Mitochondrial ATP vs Placebo
- 15.5% Increase in Time to Fatigue
NMN (400mg)
NMN is a precursor to NAD+, which is an important molecule that promotes the process of glycolysis and the kreb’s cycle.
This means it increases the rate of energy production from our body’s reserve of fats and glucose.
NMN is also known for its anti-aging benefits due to its ability to boost NAD+ production and its impact on mitochondrial health.
Specifically related to performance in amateur runners, NMN has been shown to…
- Boost Aerobic Capacity by up to 30% in Trained Athletes
- Counteracts Age-Related Muscle Decline
- 30-40% Decrease in Pro-Inflammatory Cytokines, a Marker of Exercise Damage
Beetroot Powder (500mg)
Beetroot powder is a concentrated form of beetroot, specifically designed to be taken as a performance enhancing supplement.
Beetroot is notably high in nitrates, which convert to nitric oxide (NO) in the body.
Nitric oxide helps improve blood flow, thereby improving the transportation of oxygen and nutrients throughout the body, especially during exercise.
Thus, beetroot has been shown in research to improve exercise performance in various different contexts.
- Improve Time to Exhaustion By as Much as 15%
- Increased power output and performance during exercise
- Improved Performance by 2.7% in a 16.1km Time Trial and 2.8% in a 4 km Time Trial.

recovery and endurance
I took a chance on this supplement after I saw it advertised in one of the newsletters I read and I’m pleasantly surprised. I definitely feel like my endurance and recovery have improved quite a bit.

Big impact on my VO2
I kind of hit a plateau last fall so this winter and spring I really wanted to get my VO2max number up. I spent months training with almost no change to baseline. I tried the MAS Endurance challenge and within 2 weeks my score shot up nearly 5 points. Excited to see what this means for my summer and fall.

Great but wish it had caffeine
I love the concept of this product, but I wish it had caffeine to really be called a “pre workout”. I just didn’t feel like it made me excited to workout like some other pre workouts ive tried.
