The original. Still the one to beat.
Crack OG is where it started. The formula that built the Crack name is still our best-selling pre-workout, now rebuilt with a broader stimulant matrix and a proper pump base.
One full serving (2 scoops) delivers 550 mg of caffeine across three forms, 400 mg Eria Jarensis and a stack of supporting stimulants for the hard-hitting energy, laser-sharp focus and fired-up mood OG is known for. 8 g L-Citrulline, L-Arginine and L-Norvaline handle the pump side.
20 full servings (40 scoops). Every dose on the label. Not for beginners.

What lifters say
Crack OG 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

How does Crack OG compare to the rest of the Crack line?
Crack OG contains 550 mg caffeine per full serving of 2 scoops (21.4 g), alongside Eria Jarensis and other stimulant ingredients. Crack Gold has 400 mg caffeine per full serving and Barbarian has 475 mg. The formulas differ beyond caffeine, too. 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 Crack OG with other products?
Crack OG is already a complete stimulant formula, so do not stack it with other stimulants or caffeine. Pairing it with a stim-free pump formula like Maniaco PUMP or daily creatine is fine.
