Dark Labs | Crack OG | 40 Servings

Hard-hitting stim energy with clear doses and pumps that scale up

Dark Labs Crack OG is a high-stim pre-workout that hits hard on energy first. It backs that up with enough pump and endurance ingredients to make your workout count. This isn't for everyone – it's for folks who want big-time energy, drive, and focus. The label shows everything, no hidden blends, which is huge in high-stim land where doses often get buried.

You get 4,000mg L-Citrulline per scoop. That's a nitric oxide booster – it helps widen blood vessels for better flow. Studies show it helps with pumps and performance, usually at 3-8g. One scoop is decent, but two gets you to 8g for a real pump kick.

Beta-Alanine is at 1,600mg per scoop. It builds up carnosine in muscles to fight the burn during intense sets. Aim for 3.2g daily for best results – one scoop is half, two hits the mark. You'll feel tingles right away, but the real perks build over weeks.

Agmatine Sulfate at 500mg, L-Arginine HCl at 500mg, and L-Norvaline at 125mg team up for extra nitric oxide support. Agmatine helps with pump feel. Arginine adds direct fuel.

Dark Labs Crack OG by Dark Labs contains 4000mg L-Citrulline, a clinical dose for training performance and pump.

Key Highlights

• 325mg total caffeine from three types – 200mg anhydrous, 75mg citrate, and 50mg dicaffeine malate. This mix gives a quick kick that lasts longer without a hard crash.
• 150mg DMHA – the star that makes this a real high-stim beast. It pushes you into that intense zone for serious users.
• 200mg N-Phenethyl Dimethylamine Citrate – like Eria, it lifts your mood, ramps up drive, and sharpens focus. That's what gives the locked-in, feel-good vibe during workouts.
• 4,000mg L-Citrulline per scoop – solid for blood flow and performance, backed by studies. At two scoops, 8,000mg feels like a full dose for killer pumps.
• 1,600mg Beta-Alanine per scoop – enough for those tingles and to help build carnosine. Double to 3,200mg and it matches what works best for fighting fatigue over time.
• 500mg Agmatine Sulfate – a pump helper that stacks with citrulline for better fullness and veins popping.
• 500mg L-Arginine HCl plus 125mg L-Norvaline – old-school combo to boost nitric oxide and slow arginine breakdown. Citrulline leads, but this adds extra angles for flow.
• 15mg Isopropylnorsynephrine HCl – amps up the stim feel with more edge and urgency. That's why this energy hits harder than basic pre-workouts.

Who Is This For?

• Seasoned high-stim fans who handle 300mg+ caffeine fine and want aggressive energy, urgency, and focus. 325mg caffeine with DMHA, Eria-style phenethylamine, isopropylnorsynephrine, and alpha-yohimbine deliver that punch.
• Bodybuilders in heavy hypertrophy phases needing mental fire for long sessions with compounds and volume. Two scoops give 8g citrulline and 3.2g beta-alanine for solid pumps and endurance.
• Early morning trainers who need quick switch to full-on mode. Multi-caffeine forms hit fast and hold steady.
• Advanced lifters bored with regular pre's, craving stronger central kick. This layers stims for real feel, not fluff.
• Folks who dig mood-boosted, zoned-in workouts and like Eria and DMHA. 200mg N-Phenethyl Dimethylamine Citrate plus 150mg DMHA nail that motivation.
• Users wanting full disclosure on high-stims, not mystery mixes. Every key ingredient has a listed dose for straight-up judgment.

How to Use

Begin with one scoop in 8-12 oz cold water, 20-30 minutes pre-workout to check tolerance. It's packing 325mg caffeine plus 150mg DMHA, 200mg N-Phenethyl Dimethylamine Citrate, 15mg isopropylnorsynephrine, and rauwolfia for alpha-yohimbine at full two-scoop level. If one feels good and you want more pump, try two for 8g citrulline and 3.2g beta-alanine. Shake it hard in a bottle – mixes better than stirring. Empty stomach hits faster and stronger; big meal slows it. Don't mix with other pre's, fat burners, yohimbine, DMHA, or lots of coffee same day. Stack with creatine since it's not in here. Cycle it – use for hard days or take breaks to keep tolerance down. Store sealed, cool, dry, no moisture.

What to Expect

First 0-10 minutes: taste hits, it settles, you know it's strong. 10-20 minutes: caffeine ramps, maybe beta-alanine tingles, alertness climbs, mental lift starts. 20-40 minutes: peak time – energy pushes hard, motivation spikes, focus locks in, gym feels ready to crush. 40-90 minutes: multi-caffeine keeps it going without quick drop, but tolerance matters. Days 1-7: you figure if DMHA and alpha-yohimbine work for you, tolerance might creep. Weeks 2-4: beta-alanine builds up if you're consistent, stims feel familiar. Two scoops consistent makes pumps and hard sets way better than it looks on paper.

Frequently Asked Questions

How much caffeine is in Dark Labs Crack OG Pre-Workout?

Total caffeine is 325mg from three sources: 200mg caffeine anhydrous, 75mg caffeine citrate, and 50mg dicaffeine malate. That multi-source setup is designed to hit faster than a single-source caffeine formula while staying elevated longer.

Is Crack OG a beginner-friendly pre-workout?

No. Even before factoring in DMHA, Eria-style stimulant support, isopropylnorsynephrine, and alpha-yohimbine, 325mg caffeine alone is substantial. This is an advanced high-stim formula and beginners should start elsewhere.

Why does the label show both 1 scoop and 2 scoops?

Because the formula changes meaningfully between those doses. One scoop is primarily about stimulant intensity, while 2 scoops raises L-Citrulline to 8,000mg and Beta-Alanine to 3,200mg, which makes the pump and endurance profile much stronger and closer to clinical benchmarks.

What does DMHA do in this formula?

2-Aminoisoheptane, commonly called DMHA, is included at 150mg to increase stimulation, drive, and training intensity. It is one of the main reasons this product feels much stronger than standard caffeine-based pre-workouts, though human safety data are limited compared with common sports nutrition ingredients.

Will this give me a good pump or is it mostly stimulants?

At 1 scoop, the stimulant side clearly dominates. At 2 scoops, the 8g L-Citrulline plus agmatine, arginine, and norvaline create a much more convincing pump experience, especially for users who want both intense energy and visible muscle fullness.

What side effects are most likely with Crack OG?

The most common issues are overstimulation, rapid heartbeat, jitters, anxiety, sweating, beta-alanine tingles, and trouble sleeping if taken too late. Sensitive users may feel the rauwolfia-derived alpha-yohimbine and DMHA particularly strongly.

Can I stack Crack OG with coffee or an energy drink?

That is not recommended for most users. With 325mg caffeine already present plus multiple non-caffeine stimulants, adding coffee, energy drinks, or fat burners can push the total stimulation into an unnecessarily harsh range.

Should I take 1 scoop or 2 scoops?

Start with 1 scoop to assess tolerance, no exceptions. Only advanced users who handle the first dose well and specifically want the stronger 8g citrulline / 3.2g beta-alanine performance profile should consider 2 scoops.

Does Crack OG need to be cycled?

Cycling is smart because stimulant tolerance tends to rise with regular use, especially with caffeine and DMHA-heavy formulas. Many experienced users reserve it for their hardest sessions or take periodic breaks to preserve the effect.

Does this formula contain a proprietary blend?

No. The formula is fully disclosed, which is a real advantage in the high-stim category where exact stimulant amounts are often hidden behind proprietary labels.
