Recognise this?

Before, during and after. Three moments that ask for focus.

01

Before the effort

Your head is still on work or on the road, and you want to start sharp: a training, a match, an important meeting.

02

During the effort

Halfway through, your concentration slips and every rep, every round or every task becomes work. That is exactly when you want a clear head.

03

After the effort

The session is over, your day is not: driving home, working, being there for the people around you. No sugar spike, so no crash.

Alvi, in his own words

“It does not matter where you come from or how well or badly things are going. Anything is possible, if you believe in it and work hard for it.”

The mechanism

Why a shot can be sharp and calm.

1 · Precision caffeine

80 mg caffeine. Alert, without the jitters.

80 mg caffeine contributes to increased alertness and concentration. About one good espresso, half of a typical energy drink. No sugar, so no spike and no crash an hour later.

2 · Cell energy

NR and magnesium: the energy your cells make.

150 mg NR helps maintain NAD+, the molecule your mitochondria use to produce energy. 100 mg organic magnesium contributes to normal muscle function and to the reduction of tiredness and fatigue.

3 · Flow

L-citrulline, taurine and L-carnitine.

A high-dose amino-acid matrix (3000 mg) plus 1000 mg L-carnitine. Liquid, so it is absorbed fast, formulated with ABSORPTIX® for stability and uptake.

What is in one shot

Six actives. One 25 ml shot.

01

Caffeine, 80 mg

A precise 80 mg per shot. Caffeine contributes to increased alertness and concentration. One shot, one moment.

04

05
