What’s In Dr. Jekyll Signature?

Cognizin (Citicoline)

Citicoline (Cognizin®), is a naturally occurring compound that aids in brain health, memory, and focus. It is crucial in enhancing brain energy, improving motor function, and reducing mental fatigue.


EndoFlo™ provides enhanced nitric oxide (NO) production, vasodilation, blood flow, and antioxidant levels. This helps boost exercise performance, increase endurance, and enhance nutrient transport.

Enfinity (Paraxanthine)

Paraxanthine (enfinity®) is caffeine’s primary metabolite in the human body, contributing to the vast majority of caffeine’s beneficial effects. It is a central nervous system stimulant that enhances energy, focus, and mood and improves reaction time while also reducing mental errors.


NeuroRush™ utilizes Coffea Arabica Extract to boost cognitive function, mood, and vitality, while also supporting neuroprotection. It is rich in chlorogenic acids, also known as CGA, and can enhance reaction time, alertness, and memory, making it a reliable choice for optimizing brain health and function. †


L-Citrulline is an amino acid that increases nitric oxide levels which promotes vasodilation. This increases blood flow in order to enhance exercise performance, reduce fatigue, and improve recovery.†

Betaine Anhydrous

Betaine Anhydrous, referred to simply as Betaine, is a compound found in various foods. However, the amounts obtained through diet alone are not sufficient to maximize the potential benefits of Betaine. For exercise performance, Betaine is shown to support power, strength, and endurance during resistance training and high-intensity exercise.


L-tyrosine is a non-essential amino acid, meaning that the body can produce it on its own. It serves as a precursor to several important neurotransmitters, including dopamine, norepinephrine, and epinephrine. In exercise performance, L-Tyrosine may help mitigate the effects of stress on cognitive function during prolonged periods of activity.†

Sea Salt

Sea Salt, or Sodium, helps maintain electrolyte balance which is crucial for exercise as it maintains proper hydration, nerve function, and muscle contractions. Additionally, it helps facilitate nutrient absorption including glucose, amino acids, and certain minerals in the digestive system.




To perform efficiently and effectively energy is crucial for a workout because it fuels all physiological processes from sweating to muscle contraction and repair.



Focus plays an important role in optimizing the benefits of exercise: mind-muscle connection, improving technique, enhancing performance, and reducing the risk of injury.



Hydration refers to maintaining adequate fluid balance in the body which maintains electrolytes needed for physical activity and prevents dehydration.

Amazing endurance without the jitters!

I've been trying to cut down on my caffeine consumption lately but was afraid of the trade-off in the intensity of my workouts. Decided to give this this new Jekyll a try about 3 weeks ago and I am HOOKED. I’ve been training for an open water swim and this stuff has majorly increased my endurance. It gets me completely dialed in/focused and helps reduce muscle fatigue. I just want to keep working out. This is absolutely my new go-to pre.

Thank you for taking the time to leave such a positive review for our Jekyll Pre-Workout! We are thrilled to hear that it has helped you with your endurance and focus during your workouts. We understand the struggle of cutting down on caffeine but still needing that extra boost, and we're glad to hear our product has been able to meet your needs. Keep up the great work in your training and thank you again for choosing our product as your go-to pre-workout!

Like Old School Jekyll

This reminds me of the old school Jekyll that I used to stack with Hyde (when I could handle the caffeine). It has some new age ingredients that crank up the focus and endurance, and the caffeine is in my sweet spot at about 100mg. You might hear colors and see sounds. OH, and it tastes really good. Worth the $40 for the 20 servings.

Thank you for your review of our Jekyll Pre-Workout! We appreciate your support and for choosing our product. Keep pushing through those workouts!

Fantastic flavor and results

The strawberry watermelon flavor is wonderful and the energy I get from drinking it gives me everything I need for my less intense workouts.

If I am not lifting or doing any tearing down, I am absolutely drinking this before I start my routine.

Thanks for your review, Ethan! Glad you're loving Jekyll Pre-workout!

Amazing Product and Best Tasting Pre

I have tried several pre workouts throughout my lifetime and I can say that Jekyll has to be the best tasting one I have ever come across personally. On top of the taste the formula is top notch. I like to use it for when I train at night since it is low stimulant but when I train in the morning, I like to stack it with my higher stim pre workout making this product even more versatile. I will be re upping on this asap.
