Why Use Build

This muscle-builder formula features evidence-based ingredients to help recovery and performance day in and day out.

Accelerate Muscle Growth & Strength

Made with epicatechin and elevATP® to enhance muscle hypertrophy, strength, and overall muscle performance.

Improve Endurance & Oxygen Utilization

PeakO2™ significantly boosts VO2 max, delays fatigue, and improves exercise capacity.

Enhance Recovery & Reduce Soreness

SenActiv® and PeakO2™ reduce muscle damage and improve recovery times.

Superior Nutrient Absorption

Formulated with AstraGin® for greater nutrient uptake and efficacy.

Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Peak02™ (Adaptogenic Mushrooms)

2,000 mg
Clinically studied mushroom blend that enhances VO2 max, endurance, and oxygen utilization during exercise.

Epicatechin (from Green Tea Extract)

150 mg
This green tea constituent is a putative myostatin inhibitor thought to promote muscle hypertrophy.

elevATP®

150 mg
A patented blend of ancient peat and apple extracts for boosting the body’s production of cellular energy (ATP).

AstraGin®

50 mg
A blend of adaptogenic herbs that improve nutrient absorption and support muscle recovery.

SenActiv®

50 mg
Adaptogenic herbal blend for accelerating recovery and improving exercise performance.

Peak02™ (Adaptogenic Mushrooms)

2,000 mg

PeakO2™ is a comprehensive blend of six adaptogenic mushrooms, namely Cordyceps, Reishi, King Trumpet, Shiitake, Lion’s Mane, and Turkey Tail. These mushrooms collectively enhance the body's ability to adapt to both physical and mental stressors, including high-intensity and long-duration exercise.

Clinical research has demonstrated that PeakO2™ significantly improves oxygen utilization and increases time to exhaustion, both key factors for athletes looking to push beyond their current performance limits [1]. 

Other research has shown improvements in VO2 max, anaerobic threshold, and perceived exertion in participants supplementing with PeakO2™ [2]. Thus, taking PeakO2™ can lead to marked performance enhancements in as little as 7 days.

Epicatechin (from Green Tea Extract)

150 mg

Epicatechin is a naturally occurring flavonoid predominantly found in cocoa and green tea leaves. Renowned for its potent antioxidant properties, epicatechin has garnered significant attention for its role in muscle physiology. One of its key functions is the inhibition of myostatin (growth and differentiation factor-8), a protein that negatively regulates muscle growth [3]. Furthermore, it activates adenosine monophosphate-activated protein kinase (AMPK), which is instrumental in energy homeostasis, thereby promoting lipolysis, fatty acid oxidation, and improved glucose uptake in muscle tissues [4].

Epicatechin aids in nitric oxide production, a critical factor that enhances vascularity and blood flow [5]. Improved blood flow ensures more effective nutrient delivery to muscles during physical exertion, leading to optimized muscle performance and recovery [6]. Collectively, these benefits make epicatechin a valuable addition to muscle-building and performance-enhancing regimens.

elevATP®

150 mg

elevATP® is a natural combination of ancient peat and apple extracts designed to increase the production of adenosine triphosphate (ATP), the body’s primary energy currency. This blend leverages the synergy of its components to stimulate endogenous ATP production, thereby enhancing cellular energy availability. ATP, a pivotal molecule in energy transfer within cells, is essential for muscle contractions, nerve impulse propagation, and chemical synthesis.

Supplementation with elevATP® has been demonstrated to increase intracellular ATP levels, leading to improved strength, power, and performance during high-intensity exercise. Notably, elevATP® enhances mitochondrial efficiency and supports the physiological demand for energy during strenuous physical activities. Additionally, research suggests that elevATP® may play a role in delaying the onset of muscle fatigue, thus extending workout durations and intensities​​.

AstraGin®

50 mg

AstraGin® is a patented blend of Astragalus membranaceus and Panax notoginseng. Research shows that AstraGin® can increase the absorption of various nutrients, including amino acids, vitamins, and minerals, thereby supporting overall health, energy levels, and performance [13].

SenActiv®

50 mg

SenActiv® is an adaptogenic blend of Panax notoginseng and Rose hips extracts designed to promote muscle energy and recovery. The bioactive constituents of these herbal extracts work by enhancing the regeneration of muscle cells and mitigating inflammation, thereby facilitating quicker recovery times and improved muscle endurance.

Research indicates that SenActiv® can significantly improve muscle recovery, reduce muscle damage, and support overall exercise performance. Studies have demonstrated that individuals supplementing with SenActiv® experienced decreased levels of exercise-induced muscle soreness and markers of muscle damage, such as creatine kinase. Moreover, the anti-inflammatory properties of SenActiv® contribute to the maintenance of healthy muscle tissue, reducing the risk of chronic injuries that could impede athletic progression.

I have been using Build for almost 2 weeks and can definitely feel the results of muscle recovery. Only reason why it is not 5 stars is taste. I learned the hard way to shake the container before every scoop, which helped a-lot. But because of the mushroom powders it still has a strong earthy taste.

Earn that last start with an unflavored option

I'm a broken record, going through TL's products that have been best suited to my fitness goals and regiment and rating them. All would be 5 stars if they came in unflavored options. If I need a flavor or sweetness, I'll add it myself.

Third week taking this, feel pretty good but it tastes like mango flavored bone dust. Pretty rough.

May Not Always Agree With Your GI

I was drinking this every day for a few months, in the mid morning. It took a few months of IBS like issues, and me eliminating this from my diet to realize this often did not agree with me. It does have 1300+ mg of Citric Acid, which can cause GI issues. Plus this just plain taste nasty. I never did get used to the taste. At 53, staying natural with how I'm putting on muscle I was hopeful for some results with this drink. I may try it again, but having it later in the day. I've been able to drink it sometimes and not have any issues, then other times 45 mins after drinking it, I'm off to the bathroom. Sorry for the TMI, but felt I had to warn folks.

Fruit Punch? Yeah,OK, lol.

Haven't had a chance to see how it affects my workouts yet, but unless I got a bad batch, it does 100% not taste like Fruit Punch.

Deliciou!

I love this shit. I had to remember the dose is 2 or less scoops per day cause it’s so refreshing mixed in a glass of water with ice. I may start making non-alcoholic cocktails 🍸 🍹 with it.

Tastes Like Chalk

I can't comment on the effectiveness of this product yet because I just barely started using it. So, in fairness, I will give it three stars. However, I can say like several of the other reviews, that this stuff tastes like chalk. I got the fruit punch flavor, but it barely has any flavor, other than it feels and tastes like I'm drinking chalk. I wish they had an unflavored version because then I could mix it with my post workout shake. Please create an unflavored version. Thank you

BUILD!

First time trying out Build (Peach Mango flavor) and while I can't say I'm a fan of the chalky like taste, I don't take it for the taste, I do so because of what's in it.

Although I haven't been taking it for too long, I believe Build is helping me push myself harder and is giving me the strength to work towards my fitness goals. I will continue taking it and see where I go with it.

Tastes great, another superb product in their lineup

I am halfway through my first container and have nothing but great things to say so far. After reading the reviews I was concerned about how this product would taste, especially since people were complaining about the "mushroom taste". I found that the taste is very palatable, close to the fruit punch flavor and mixes very well. The container opening and spoon length were fine, a lot of people were complaining, they must be akin to Andre The Giant. Too early to tell how the supplement is aiding me in the gym but so far I have nothing but great things to say!!

Great supplement!

This is a must have if you’re serious about lifting, it gets me through those heavy compound movement without feeling winded or fainted. I can feel the difference if I stop taking it for a while had to subscribe to it.

Great supplement! Wrong container.

I think this is a great supplement. I can’t guarantee that it’s effective, but I do think it has helped me recover and add additional mass. It certainly can’t hurt to add into your routine and if anything it helps me get another 32 ounces of water a day. The only problem is that the container is incredibly inconvenient when you get down to the last week or so. The mouth is too small to be able to fit your hand in and effectively scoop the supplement out. To make it easier, you either need a longer spoon or one of the widemouth containers.
