Bottom Line

Dark Labs has been hitting top 10 lists for pre workouts for ages now.

They are a Polish company who know how to bring the exotic stimulants to hard hitting formula's.

From the original Crack to the special editions like Gold, no company has been this consistent with their formula's.

With 120mg in the original Crack, and a whole bunch of nitrates, you'll be getting some hardcore energy along with nasty pumps. 

The Gold edition seems to come and go, and that has both DMAA (100mg) and DMHA (200mg).

If you want more energy than pumps, then go for the Gold Edition. 

But if you want more pumps then energy, then go for the original.

Looking for a potent pre workout?

How about one with lots of DMAA and nitrates?

Crack doesn't only have 120mg DMAA but it also has nitrates, nitic oxide boosters and nootropics.

And Dark Labs doesn't just specialize in DMAA pre workouts.

Check out their Flame pre workout with 500mg eria jarensis. 

Crack features a formula that you haven't seen before. 

Typically, you'll see DMAA dosed from 60 to 80mg, with some going as high as 100mg. 

Crack is quite a potent pre workout with a unique take on mixing 120mg DMAA with lots of pump inducing ingredients. 

And they are consistently releasing potent pre workouts, like Crack Primal, a 500mg eria jarensis product that is sure to light a fire under you.

A quick note, the ingredients that are crossed out are the ones used for the original Crack version, which can still be bought. 

My Crack Review

Dark Labs' Crack OG is a pre-workout supplement that's not for the faint-hearted.

It's designed for advanced users, and I can see why from the moment I take it.

Within 20 minutes, I'm hit with a wave of warmth and energy that feels like a smooth ride that elevates as smoothly as an airplane.

The energy is intense, but it's also smooth, not overwhelming.

By the 30-minute mark, the effects are maximized.

I'm filled with a sense of urgency, a need to get to the gym and start my workout.

I can't sit still, and I'm focused on my workout like never before.

The DMAA in Crack is noticeable, but it doesn't cause vasoconstriction like I might expect.

Instead, the nitric oxide boosters in the formula help to increase vasodilation, leading to better pumps.

During my workout, Crack really shines. I'm able to push myself harder and faster, and my rest periods are minimal. I'm in the zone, focused on my workout and nothing else.

The effects of Crack last for hours, and there's hardly any crash.

Even three hours after taking it, I'm still feeling energized and ready to go.

The flavor of Crack OG is decent, but it's not the star of the show.

The real standout is the formula, a potent blend of stimulants that delivers an unmatched pre-workout experience.

But be warned: Crack is not for everyone.

It's a highly potent pre-workout that should be used with caution.

If I were new to pre-workouts or sensitive to stimulants, I might want to start with something milder.

But as an experienced user looking for a pre-workout that can keep up with me, Crack OG might just be what you're looking for.

Dark Labs did a great job formulating both Crack and Crack Gold. 

For the original Crack, DMAA is dosed high, at 120mg, there's nitric oxide boosters like nitrates and agmatine to help keep blood pressure under control.

Every dosage disclosed but everything is clinically dosed, aside from the 1.5g of beta alanine which should be supplemented on it’s own anyway. 

The stimulants are packed, looking at 400mg caffeine and 120mg DMAA, no one should be taking a full serving unless they are prepared for this.

Citrulline malate, agmatine, and arginine nitrate are the big nitric oxide boosters and the pumps will last long thanks to the defensive L-Norvaline.

This is also topped off with Grains of Paradise for fat burning, though you’d still be getting thermogenic effects from the big combo of DMAA and caffeine. 

For the Gold Edition, there's less nitric oxide boosters and more exotic stimulants with DMHA, DMAA and eria jarensis. 

Let’s dive into the ingredients…

Citrulline Malate 2:1 (8g)

Citrulline is the better version of arginine as it’s been accepted that this is the superior version to have. 

The problem with arginine is that it is just not as bioavailable as it should be. 

And anything over 10g causes gastronomical issues.

Citrulline is not only highly bioavailable but it is much more effective at increasing nitric oxide levels, decreasing muscle soreness and enhancing recovery. 

In fact according to research performed in 2010, citrulline can increase reps by 52.92%, due to its ability to decrease fatigue and increase oxygen.

It can improve blood flow, leaving your muscles more full with nutrients and blood, allowing you to reach a solid pump. 

Clinical doses starts with 6g going up to 8g, and Crack has 8g which will give you maximum benefits from citrulline. 

So by the time you take Crack, the energy will settle in hard and you’ll be more pumped thanks to the citrulline in here and you’ll be motivated as you’ll also be able to workout longer.

Beta Alanine (3g)

Beta alanine is one of the most researched ingredients out today. 

It is often used with supplements like creatine because they both work in synergy. 

Being a derivative of alanine, beta alanine has power and endurance boosting properties especially for exercises that last anywhere from 60 to 240 seconds. 

While people may either hate or love the tingling sensation, it’s one ingredient that you’ll feel it instantly working when taking it. 

Beta alanine is a must have because it increases carnosine levels, helping clear and delay the lactic acid build up that causes the burning sensation you get from performing high reps. 

To take full advantage of these ingredients, it’s recommended to dose it at 3.2g on a daily basis as it takes time to saturate your muscles like creatine. 

It’ll not only help with endurance but it’ll also increase power output, strength, and all in all helping increase work capacity as it will help maintain intensity for longer periods of time. 

If you can’t stand the tingles, try splitting the serving in half, you’ll still be getting 60mg dose of DMAA along with the other ingredients here that are generously dosed.

Agmatine (1.5g)

Agmatine in a high stimulant pre workout is an absolute must because DMAA may elevate blood pressure. 

Aside from that, it’s popular for it’s nitric oxide abilities as it can elevate N.O. levels and prolong those levels for long periods of time. 

This translates to better, longer lasting pumps, even long after your workouts. 

Agmatine is a metabolite of L-arginine and it has an incredible bioavailability rate, making it much more effective at increasing nitric oxide levels. 

Citrulline works in synergy with agmatine and citrulline increases arginine while agmatine protects arginine from being broken down. 

Normally a dose that ranges from 800mg to 1g is used in pre workouts, while higher doses are found in nitric oxide focused supplements. 

But Dark Labs is using a massive 1.5g.

So even at half a serving, you’re still getting the best of both worlds, from energy to long lasting pumps. 

Arginine Nitrate (1g)

We’re not done with nitric oxide boosters yet…

Arginine is known for being inferior for its bioavailability, but when you attach a nitrate to it, it becomes something else entirely. 

Using arginine that’s bonded with nitrates helps tons because it decreases the risk for nitrate tolerance, which is common when taking nitrates. 

Like agmatine, nitrate is effective at increasing vasodilation, allowing for more oxygen rich blood to be delivered to working muscles. 

This will let you put in more work into your workouts, as your oxygen expenditure will be decreased and you’ll less likely be fatigued towards the end of your workouts. 

At 1g, you’re getting a sufficient dose here as agmatine, citrulline and even beet root powder is included in Crack. 

And the next ingredient is naturally rich in nitrates….

Beet Root Powder (1g)

Beet root powder is typically used in nitric oxide formulas because of it’s naturally high content of nitrates. 

As mentioned, nitrates are effective at increasing blood flow allowing more nutrients to be delivered to your muscles. 

This will have a massive synergistic effect with the other nitric oxide boosters here and there’s even norvaline, another effective addition for the pumps.

L-Norvaline (250mg)

Crack Reloaded by Dark Labs

Coming out of the Polish company, Dark Labs, Crack Reloaded is the first pre workout without DMAA and DMHA.

It's loaded with 500mg eria jarensis, and a load of stimulants to help provide aggressive focus along with decent pumps.

Also available from MySupplementPlug, and SuppsCentral.

  • Strong focus and energy
  • Solid mix of nootropics
  • Long lasting
Ingredients: 6g Citrulline Malate, 3.2g Beta Alanine, 1g Choline Bitartrate, 1g Agmatine Sulfate, 1g Lion's Mane, 600mg Alpha Gpc 50%, 100mcg Huperzia Serrata
Stimulants: 500mg Beta-Phenylethylamine, 500mg Eria Jarensis, 350mg Caffeine, 150mg Caffeine Citrate, 100mg Dicaffeine Malate, 100mg Theobromine HCL, 50mg Isopropylnorsynephrine, 30mg Noopept, 2mg Alpha Yohimbine

Norvaline comes from the amino acid valine, and it works similarly to agmatine. 

It prevents the enzyme that eats away arginine in the bloodstream, allowing it to be a defensive type of nitric oxide booster.

It’ll prolong the pumps and allow for more arginine to be available in the blood. 

There’s already 3 highly effective nitric oxide boosters to attack the pump from different angles, from producing nitric oxide and prolonging the effects and keeping them at higher levels for a longer period of time. 

Needless to say, you’ll be getting huge pumps with this and we still have stimulants and nootropics to cover…

Choline Bitartrate (500mg)

Choline is an essential nootropic to have as it can reinforce the integrity of cell membranes. 

It can do multiple things from increasing acetylcholine production, to being oxidized into betaine. 

When it’s oxidized into betaine, it can increase cognitive function and enhance cardiovascular health.

Caffeine Anhydrous (400mg)

The 300mg dose here of eria jarensis is fairly big and it'll have some nice enhancements to the mood especially as it's combined with both DMHA and DMAA. 

It works by increasing dopamine production so you'll not only feel good but you'll also feel motivated and uplifted to workout.

Eria Jarensis (300mg)

There's 300mg of anhydrous and 200mg of caffeine citrate. 

Caffeine is the godfather of stimulants and it’s one of the most proven stimulants as it’s highly researched and backed by hundreds of studies. 

It decreases adenosine allowing you to feel energized and alert. 

The 500mg dose with DMAA is quite high, hence why we’ve been recommending to take half a serving or even less. 

At half a serving you’re still getting nice doses of nitric oxide boosters and more.

DMAA (120mg)

Gold Edition has both 200mg DMHA and 100mg DMAA, while the standard edition has 120mg DMAA.

DMAA is the controversial stimulant that is usually hard to find. 

It’s stronger than DMHA and it works better when it’s paired with caffeine.

(Read about Wild Fire, a pre-workout with both DMAA and DMHA)

Similarly structured to amphetamines, DMAA enhances mood as well as focus while barely affecting heart rate, at least in doses under 80mg. 

When you get as high as 120mg, the risk for elevated blood pressure increases, especially when you pair it with 400mg caffeine as it is here. 

The FDA has been making it difficult to get this stimulant, however it is here in a big amount. 

Stick to half a serving or even less and you'll get plenty of stimulants and nitric oxide boosters.

(Read: What is DMAA?)

Sceletium Tortuosum Extract (25mg)

Kanna, scientifically known as sceletium tortuosum extract, is a herb known to decrease stress and anxiety. 

It works through selective PDE-4 inhibition and it also works as a 5-HTP reuptake inhibitor.

This means it won’t only be useful for stress and anxiety reduction but it can also increase blood flow, leaving you with better and long lasting pumps.

Grains of Paradise (15mg)

Grains of paradise has a thermogenic effect and it’s typically found in fat burners. 

It’s similar to ginger, burns fat effectively without being a stimulant. 

Since it’s high in 6-Gingerol and 6-Paradol, it’ll help decrease visceral fat.

It does this by transforming adipose tissue into brown adipose tissue, basically allowing greater energy expenditure. 

The dose at 15mg is a bit low but there’s already high doses of stimulants and this isn’t meant to be a fat burner anyway.

The 120mg DMAA Pre-Workout King

Crack OG by Dark Labs is a pre-workout supplement that has been making waves in the fitness community.

Released in 2019 by the Polish supplement company, this pre-workout is known for its bold inclusion of 120mg of DMAA, a dosage significantly higher than what is typically found in DMAA pre-workouts.

This, coupled with an impressive portfolio of pump ingredients, makes Crack OG a standout product in the market.

The formula is designed to deliver both energy and pumps, making it a rare find in the pre-workout category.

The stimulant package, which includes 400mg of caffeine and a variety of nootropics, is the highlight of the show.

However, the pump ingredients, including 8 grams of Citrulline Malate, 1.5 grams of Agmatine Sulfate, and nitrates, are not to be overlooked.

The experience of using Crack OG is described as a full-blown stim junkie hardcore experience

. It takes about 30 minutes to reach full lift-off, but once it hits, it delivers intense pumps, mood elevation, and energy that lasts for 4-5 hours.

The effects are powerful and long-lasting, making it a favorite among advanced users.

Despite its potency, Crack OG is not just about the stimulants.

It also includes ingredients like Beet Root Powder for improved cardiovascular capacity and endurance, and Grains of Paradise for fat-burning and antioxidant properties.

The inclusion of these ingredients shows a thoughtful approach to formulation, balancing high-stimulant ingredients with those that support overall workout performance and health.

Gold does a good job with stimulants, although it struggles a little with ergogenic ingredients like citrulline and beta alanine. 

At half a scoop, you'll get 500mg agmatine, 250mg caffeine, 150mg eria jarensis, 100mg DMHA, and 50mg DMAA.

A little over half a scoop and you'll bump up those numbers.

Compared to the standard version, you'll get less ergogenic aids, nitric oxide enhancers and more stimulants. 

Much more stimulants. 

The standard version has 120mg DMAA, while a lot, more isn't necessarily always better. 

DMAA works fantastic when it's dosed around 80mg, anything more than that and it gets a little risky for elevating blood pressure. 

But the standard edition does have more nitric oxide boosters to help lower blood pressure and increase pumps.
