Bottom Line

Crack Purple has been reformulated without DMAA.

Now it delivers a high-stim blend featuring 240mg DMHA, 400mg caffeine, 300mg Eria Jarensis, and 200mg caffeine citrate.

The energy lasts a long time and feels smoother compared to the original.

You’ll still get high levels of motivation, mood enhancement, and focus.

Pumps are reduced—no nitrates this time.

It’s designed for advanced users who want intense workouts without chaotic stim crashes.

If you're sensitive to stims, skip it—or start with a half scoop.

Let’s break down the new formula.

The original Crack pre-workout was legendary.

DMAA, insane energy, dialed-in focus, and vasodilation so strong it made your skin feel tight.

But that version’s gone.

Dark Labs sold the company, and the new owners reformulated everything—including Crack.

This is the updated version.

Same name. Same aggressive look. Different formula.

Still intense?

Yeah. But in a new way.

My Crack (Original Formula) Review

DMAA + PUMPS
Crack by Dark Labs

This pre-workout is being discontinued, get it while you can. Crack is one of the popular pre-workouts and is one of the few good DMAA pre-workouts. Crack packs 120mg DMAA along with nitrates and nitric oxide boosters.

Pros:
  • Strongest DMAA pwo available
  • Legit company and label
  • Strong pumps and formula
Ingredients: 8g Citrulline Malate, 3g Beta Alanine, 1.5g Agmatine Sulfate, 1g Ariginine Nitrate, 1g Beet Root Powder, 500mg Choline Bitartrate, 250mg L-Norvaline, 25mg Sceletium Tortuosum Extract, 15mg Grains Of Paradise
Stimulants: 400mg Caffeine, 120mg DMAA

Ingredients

Pump and Performance Support

  • Citrulline (8g): Boosts nitric oxide levels for increased blood flow and pumps.
  • Beta-Alanine (3g): Aids endurance by buffering lactic acid.
  • Agmatine (1g): Enhances blood flow and prolongs nitric oxide effects.
  • Choline Bitartrate (500mg): Supports focus and cognitive function.

Energy and Stimulants

  • Caffeine (400mg): Standard stimulant for focus and energy.
  • DMHA (240mg): Provides sustained energy but lacks the sharpness of DMAA.
  • Caffeine Citrate (200mg): Delivers rapid energy onset.
  • Eria Jarensis (300mg): May enhance mood and focus, though effects vary.
  • Halostachine (50mg): A milder stimulant with potential fat-burning properties.
  • Alpha Yohimbine (2mg): Known for its thermogenic effects, but can cause side effects like jitters.

The old formula can be seen in the image below:

Our Thoughts

The reformulated Crack focuses on a balanced approach with pumps, sustained energy, and cognitive support.

While the removal of DMAA addresses regulatory concerns, its absence may result in a less aggressive energy spike. DMHA and the dual caffeine sources attempt to fill the gap, but the overall experience could feel smoother and less intense for previous users.

For now, it’s unclear how this version will be received, as there isn’t enough feedback to determine whether it matches the legacy of the original Crack. Advanced users may find the new formula reliable, but its impact compared to DMAA-based products remains uncertain.

Crack Purple

March 27, 2025

I mixed a full serving ( 17 grams ) into a cold bottle of water and it mixed fine with no issues.

The taste ( Dark berry ) I found to be awful but I held my nose and chased with plain water.

The effects kicked in rather fast and I noticed not only beta alanine tingles but a redness to my face and chest similiar to a niacin flush ( i'm guessing this is the beet root powder)

Then shortly the stimulants took hold and my head had a highness floaty feeling and I felt the urge to put loud music on and lift heavy.

I did a full body workout and noticed I was stronger than usual on a pre workout, maybe 5-10% increase on lifts.

It had very potent pumps for a high stim product, it was lacking in focus nootropic elements however.

Overall it was a great hitter every time and it is a shame products like this are rarer by the day, I would give it an 8/10.

RIP Original Crack Purple

February 20, 2025

Bought Crack purple original formula in 2021 from suppscentral using an FDN discount code after seeing the hype it was getting from reviewers. I used the whole tub over about two years and absolutely loved it.

I'm not sure if there was 'real DMAA', since this is my only experience with a preworkout that even CLAIMS DMAA. But whatever is in here, it makes for an amazing preworkout and seems much stronger than just the usual DMHA.

I had Very Dark Berry flavour and it was quite good.

On a full serve (2 scoops), it takes about ~15 minutes to first kick in, and from there the focus, good mood, and driving energy builds progressively for another hour or so. Adrenaline is pumping and you feel powerful: you can do higher weight and more reps without getting fatigued. You don’t get much euphoric mood elevation per se. You're just dialled in and feeling positive about the workout.

The peak of the effects last from about ~40 minutes to ~2 hours after ingestion. You can still feel it floating around your system for a fair few hours after, so it may disturb sleep if you take it after 5pm.

The pump formula is obviously exceptionally good for a high-stim preworkout like this. And it delivers. Great muscle contractions and a surprisingly big pump for something with so many vasoconstricting stimulants.

Side effects are minimal and basically limited to what can be expected from a preworkout like this: e.g increased heart rate, shaky hands, maybe a bit of a crash, queasy feeling, headaches, I possibly threw up one time, and increased sweating (which might be a positive for some).

Overall, this is a top-tier preworkout which delivers in all areas. This review has been mainly based on the 2 scoop (full serve) experience. However I also used 1 scoop and 1.5 scoops on different occasions, with the effects being basically the same but just a bit attenuated. This preworkout is clearly ‘hardcore’, so start with 1 scoop to assess tolerance. I even think that some people will find 1 or 1.5 scoops to be more than enough.

It’s a shame that Dark Labs is pivoting away from DMAA stuff (though again who knows if it was in here) due to legal and manufacturing issues, and that the original Crack purple that I had is probably never coming back. I’m glad I got to try this one while it was in its prime.

TLDR: Hardcore preworkout specialising in strong adrenergic energy that makes you feel powerful while lifting, with intense focus and positive mood. If you can find the original formula anywhere I would say get some now because it’s going to be all gone very soon if it isn’t already.

Best of the best

January 2, 2025

All time favorite pre workout. Cover it all. Energy, mood elevation, Euphoria, insane pumps, post workout buzz, feeling on top of the world. No sides, no drama. Taste is also great. I have tropical punch

I think DL gonna bring it back soon.

Pumps are unmatched, don't need to stack anything on top, maybe Glycerol. Generally it's pretty consistent pre. 2 scoops weights less than recommend 17 grams, so use scale. Post workout mood elevation is on another level. You feel light, happy and go on about your day like you didn't had hard workout. Mind muscle connection is my favorite traits as well.
