The #1 Choice For Tested Athletes

Unleash Your Best Performance With Kairos

A Revolution In Pre-Workout Nutrition

Kairos Nutrition was created by two college students in Oklahoma City who were passionate about sports performance but couldn't find a formula that was both effective and banned substance free. They took matters into their own hands, devoting countless hours to researching and experimenting to find the best ingredients and dosages.

Their mission was clear: to create the ultimate line of supplements for tested athletes of all disciplines. Whether you’re a beginner or a seasoned pro, Kairos Nutrition brings you a fully dosed, banned substance free formula to boost your performance in the gym and on the field.

What’s with Critical Pre-Workout?

Backed by Science

We believe that your pre-workout should be just that - a supplement specifically designed to enhance your gym performance. That's why we made sure to leave out all the filler ingredients other companies sneak in. You know the ones - the unnecessary vitamins and minerals that do nothing for your workout. Instead, we included clinically-dosed adaptogens, a powerful ingredient not found in any other pre-workout on the market.

These adaptogens work to optimize your hormones, so you can crush your workout and see real results. So, don't settle for a "multivitamin in disguise" pre-workout. Choose Critical and unlock your strength potential.

FREQUENTLY ASKED QUESTIONS

Can both male and female athletes take Critical?

Absolutely! This formula is designed with clinically-dosed ingredients that are safe and effective for both genders. Each ingredient is also safe for long-term use, making our pre-workout the perfect choice for athletes of all levels.

How and when should I take it?

Simply mix 1–2 scoops of Critical with 6-8oz of water for 1 scoop, or 10-12oz of water with 2 scoops. Then, consume it 15–30 minutes before your training or athletic endeavor. Please note that we do not recommend "dry scooping" as it is more effective when when taken with water.

Does Critical contain high levels of stimulants?

Each scoop of Critical contains 200 mg of caffeine and 50 mg of theobromine. A single scoop is a tolerable dose that most people find effective. However, taking 2 scoops will provide a much higher level of stimulation and is recommended only for those who are familiar with their tolerance and can handle it.

Does a single scoop of Critical provide effective results?

Definitely! It provides the perfect balance of performance and focuses for those who prefer a milder stimulant effect. With 200 mg of caffeine and a clinically-dosed blend of nootropics and ergogenic aids, a single scoop will give you the boost you need to take your training to the next level, time and time again.
