What Crack Barbarian feels like

  • Dialed-in session intensity
  • A no-distraction, no-hesitation training headspace
  • Hard push pacing from start to finish
  • A serious, take-the-set-personally attitude

All in. No pacing. No apologies.

If you've been lifting long enough to know when a pre-workout hits and when it doesn't, you already know most formulas are all talk. Crack Barbarian is for the lifter who's past the beginner-hype stage and wants something that matches the way they train.

This is the switch you flip when the session matters. It's built for aggressive, locked-in training days where the rest of the room disappears and it's just you, the weight and the work in front of you.

25 servings, 25 chances to train like you mean it. Not for tourists.

Full formula. Doses per full serving (1 scoop)

L-Citrulline

6,000 mg

Commonly used in high-output formulas to support a full, dense, powerful training feel — especially during heavy or high-volume work.

Beta Alanine

3,200 mg

The signature "it's time to move" sensation. Signals that the warm-up mindset is over and the real session has begun.

Agmatine Sulfate

1,500 mg

Chosen for lifters who like a strong mind-to-movement connection and a fuller, more engaged feel throughout the set.

L-Tyrosine

1,000 mg

Paired with Alpha GPC for a locked-in, steady headspace — keeps the mental side composed while intensity rises.

Alpha GPC (50%)

500 mg

Selected for a controlled, coordinated training focus that stays clear under load.

Eria Jarensis Extract

350 mg

Adds a driven, confident training mood on top of the caffeine base.

Crack Barbarian FAQ

Still deciding? Email info@darklabsofficial.com and a real person will answer.

How should I take it?
Start with half a serving to assess your tolerance. Mix one full serving (serving size is listed on the label) with 8–12 oz of cold water and drink it 20–30 minutes before training. Do not exceed one full serving in 24 hours, skip other caffeine sources that day, and avoid taking it within 6 hours of sleep.
Is it suitable for beginners?
No. This formula is built for experienced lifters who already know how they respond to stimulants. If you are new to pre-workouts or sensitive to caffeine, start with Crack Initiation or Crack Daily.
Why do I feel a tingling sensation?
That is beta-alanine. The tingle is a normal, temporary sensation that fades within 30–60 minutes and becomes milder with regular use.
Where does my order ship from?
Orders ship from our US warehouse. Estimated delivery: 2–6 business days after dispatch. Delivery times are estimates, not guaranteed, and may vary by destination, carrier or customs clearance. US orders over $100 qualify for free standard shipping.Shipping policy
What if it's not for me?
Unopened, factory-sealed products can be returned within 30 days of delivery. See our returns policy for details.
How does Barbarian compare to Crack OG and Crack Gold?
Barbarian has 475 mg caffeine per full serving, plus 6 g L-Citrulline and 1.5 g Agmatine Sulfate. Crack OG has 550 mg caffeine per full serving of 2 scoops (21.4 g), and Crack Gold has 400 mg per full serving. Individual responses vary: some people find OG the strongest, while others find Barbarian stronger. Follow the serving directions and warnings for each formula.
Can I stack Barbarian with other products?
Barbarian is already fully loaded, so do not stack it with other stimulants. Pairing it with a stim-free pump formula like Maniaco PUMP or daily creatine is fine.
