The pre-activity shot is designed to enhance endurance and performance for athletes by giving your body a boost of cellular energy. Formulated with scientifically-backed ingredients to activate cellular energy metabolism.

The shot contains a patented formula with powerful ingredients like Oleuropein, Magnesium, and Vitamins B6 & C. These ingredients fuel cellular energy production, while Caffeine and Guarana provide an extra surge of energy to enhance endurance and fight fatigue.

Extended Endurance
Provides up to +6h of peak mitochondrial performance, allowing athletes to push further and longer¹.

Combat Fatigue
Contains Caffeine, Guarana, and essential vitamins to delay fatigue onset, keeping athletes stronger for longer periods¹³.

Improved Oxygen Delivery
Enhances oxygen uptake, delivering more energy to muscles for improved performance¹⁰.

ATP Maintenance
Ingredients like L-Citrulline support ATP levels, aiding in muscle recovery and reducing fatigue¹¹.

Take one shot approximately one hour before shorter runs and 30 minutes before longer runs, training sessions, or competitions.

For longer activities, consider taking another shot during training.

A shot of endurance performance for your engines

OLEUS' patented formula contains a potent dose of Oleuropein, alongside energy-optimizing nutrients such as Magnesium and Vitamins B6 & C, to fuel cellular energy production¹⁶. While the stimulating effect of Caffeine and Guarana delivers an additional surge of energy that enhances endurance and delays the onset of fatigue¹³. 

4 reasons why you should use our Pre-activity shots

  • More miles
    from your

    +6h of endurance performance¹ from your mitochondrial motors that lets you get the most out of every session⁴.

  • Feel

    Caffeine and Guarana deliver a surge of energy and delay the onset of fatigue¹³, while carbohydrate-electrolytes enhance endurance¹.

  • Increase

    More oxygen delivered to your cells means more energy delivered to your muscles¹⁰.

  • Maintenance
    of ATP levels

    L-Citrulline supports the reduction of excess lactates occurring during intense exercise¹¹.

Active ingredients


→ Olive leaf extract (Oleuropein) titrated in Oleuropein has antioxidant activity.

Guarana Seed Extract|364mg|22% Caffeine

→ Guarana is a source of energy, helps to make you feel more energetic, strengthens immunity, and suppresses feelings of hunger and fatigue.

Carbohydrate|26g & Electrolyte Solution|185 mg

→ Carbohydrate—electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise, time to exhaustion, and delays fatigue. It helps improve performance towards the end of endurance events. 


→ Helps to delay the onset of fatigue. Helps to maintain energy levels for prolonged periods during intense competition/exercise and helps to maintain peak effort during times of high physical demand. It makes energy metabolism more effective.


→ Maintenance of ATP levels through the reduction of lactates in excess for improved recovery from muscle fatigue.

Vitamin b: B1 - 1,1mg|B2 - 1,4mg |B3 - 16mg|B5 - 6mg|B12 - 2,5 mcg

→ Vitamin B group contributes to normal energy-yielding metabolism and the immune system.

Vitamin C|15 mg

→ Vitamin C contributes to maintaining the normal function of the immune system during and after intense physical exercise, and is a cofactor in the synthesis of carnitine which plays a role in energy production in the mitochondria.

Take the OLEUS Pre-Activity Shot approximately one hour before your shorter runs, and thirty minutes before longer runs, training sessions, or competitions. This natural energy boost is powered by Guarana, essential vitamins, and amino acids, delivering an additional surge of energy that enhances endurance and delays the onset of fatigue¹³. For those longer outings, feel free to repeat another during the training.

We recommend taking one Daily Shot every day. Pre-activity Shot should be taken 30-60 mins before the training or competition, and for those longer outings, you can repeat another during the session. And, one Recovery Shot should be taken after the activity. 

OLEUS has created a complete system designed to support your cell energy metabolism² through every performance stage. So we recommend incorporating all three shots into your routine. However, each OLEUS product is designed to provide specific benefits, and you can certainly choose the one that aligns with your needs.

OLEUS was developed by a team of research scientists from the University of Lausanne specializing in mitochondrial function.

OLEUS is made for serious and amateur endurance athletes who compete or train 1-5 times per week with at least one session over 2 hours.

We push the limits of cellular performance, so you can push your own

There are two parts to creating energy in the body. The first part is the fuel you consume. The second part is what happens in your cells, when the mitochondrial engines turn this raw fuel into ATP energy. 

It’s this cellular energy that powers every step, every flex, every stroke, and every pedal we make. The more efficiently they are able to do their jobs, the more energy is delivered to your muscles. The longer your cells stay at their peak, the longer you are able to run, cycle, or swim. 

OLEUS has created a simple but complete system to support your cell energy metabolism² through every stage of performance. Because the better your cells perform, the better you can.
