You’ll feel it.

Five sensations. Behind each one, grams.

The tingle.

The signal

It stings: face, hands, neck. That’s the beta-alanine kicking in. Now you know it’s time to pull heavy.

  • 6 g beta-alanine
  • 200 mg caffeine
The science
800 mg
Beta-alanine tingles from this threshold, in a single serving.
6 g
The dose in one ROK scoop: 7.5 times that threshold. The tingle is on purpose and passes within minutes.
200 mg
Caffeine rises within the hour. The effort feels easier.

Locked in.

Focus

You step into your bubble. The gym noise fades, there’s just the bar and your reps. Focused, you stay clean on every rep: that’s how you avoid bad positions and injuries.

  • 200 mg caffeine
  • 2 g L-tyrosine
  • 3 g taurine
The science
200 mg
Caffeine: perceived effort drops.
2 g
L-tyrosine: fewer attention errors under acute stress, at this exact dose.
3 g
Taurine with caffeine: faster reaction time than caffeine alone (meta-analysis).

The pump.

The pump

Citrulline raises NO. NO opens the vessels and blood fills the muscle. The pump comes fast and holds until the end of the session.

  • 10 g L-citrulline
  • 3 g taurine
The science
10 g
L-citrulline becomes arginine, then NO (nitric oxide). NO opens the vessels.
10 g
The dose chosen by the 2 to 15 g dose study. Above it, arginine production saturates.
3 g
Taurine manages water and calcium inside the muscle cell.

Past the burn.

The last reps

The burn comes later. The reps where you used to quit, you finish.

  • 6 g beta-alanine
  • 10 g L-citrulline
  • 200 mg caffeine
The science
1 to 4 min
The efforts where beta-alanine helps: it loads muscle carnosine, which buffers acidity.
10 to 20 min
Until the tingle hits: the signal to go load the bar.
+ reps
More reps on the last bench press set with citrulline.

Still standing.

The day after

Heavy leg day yesterday. Today, you still take the stairs like normal.

  • 10 g L-citrulline
  • 3 g taurine
The science
−40%
Soreness at 24 and 48 h with 8 g of citrulline malate.
2 trials
The effect shows up again in a second trial.
10 g
The pure citrulline in one ROK scoop, above the doses studied.

No spike. No crash.

The crash comes from caffeine when there’s too much at once: everything, then nothing. ROK peaks lower, holds the whole session and comes down on its own, never below where you started. The session itself runs on 21 g of non-stimulant actives.

Last questions.

It tingles. Is that normal?

Yes. It’s the beta-alanine, 6 g per scoop. The sensation is well known and passes within minutes. If it bothers you, take half a scoop.

Will it make me crash?

ROK is built to avoid the spike-then-drop: 200 mg of caffeine, not 300 or 400, and 21 g of non-stimulant actives carrying the session. Keep it to one scoop and count the day’s coffee.

How much caffeine?

200 mg per scoop. One scoop a day, no more. Count your coffee and energy drinks for the day too.

Why pure citrulline?

Because the printed number is the real number. 6 g of 2:1 malate is 4 g of citrulline. Our 10 g are 10 g of citrulline.

What does it taste like?

Blue raspberry, tart. Best ice cold.

Wake the heavy.

One tub, 20 scoops, 21.2 g of actives in each.
