How do I take the Pre-Activity Shot?

One 60ml shot, about an hour before you ride. Shake well and drink cold. One shot per day at most.

What's in it?

Six actives, all disclosed at full dose.

  • Olive leaf extract, standardised to 100mg oleuropein
  • Acetyl-L-carnitine 375mg
  • L-citrulline 675mg
  • Magnesium 56.25mg: contributes to electrolyte balance and to normal muscle function
  • Vitamin C 40mg and B vitamins: contribute to normal energy-yielding metabolism
  • Caffeine from guarana 80mg: helps increase alertness and improve concentration

No proprietary blends. High caffeine content. Not recommended for children or pregnant or breastfeeding women. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle.

Do I take it on the bike?

No. You take one 60ml shot about an hour before you ride, not during, so there is nothing extra to carry or eat on the bike.

How often should I drink OLEUS?

One shot per day at most, about an hour before your long rides and hard sessions.

Can I pause or cancel my subscription?

Anytime, from your account. No calls, no forms: pause, skip, or cancel in one click.

The problem

Starting fast is easy. Finishing strong is the fight.

A gel or an energy drink hits fast and is gone just as fast. What follows is the drop, and it always arrives in the back half, where the ride gets decided.

  1. Dead legs at hour three

    Three hours in, the same effort costs twice as much. The last climbs get ridden on whatever is left rather than what you trained for.

  2. Cramping and heavy climbs

    Heavy legs the moment the road tilts, and a cramp waiting behind them. Long, hot rides take a lot out of you.

  3. A stomach that stops cooperating

    There is a limit to how much fuel your gut will take, and long rides find it. Past that point more gels do not become more energy, they just sit there.

How it works

What each ingredient is there for.

Energy

Big efforts demand more from your energy system. B vitamins and vitamin C contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue.

Focus

Long rides test your focus as much as your legs. The caffeine from guarana helps increase alertness and improve concentration. High caffeine content. Not recommended for children or pregnant or breastfeeding women.

Muscles

When the road tilts up, magnesium contributes to normal muscle function and to electrolyte balance.

Defences

Big training blocks load the whole system. Vitamin C contributes to maintaining the normal function of the immune system during and after intense physical exercise.
