Expert Review
Nader Qudimat
Pre-Workout Expert · 20 years training

Energy is very strong but feels uneven, with ups and downs that can make breathing and pacing harder.

It can feel heavy on the heart with some tightness and dizziness, even during lighter exercises.

Focus is decent, but the overall feel is rough and less controlled than other versions.

Bottom line: Only for people who want very strong, chaotic energy, not for balanced or controlled workouts.

Crack purple by Dark Labs
The infamous purple tub itself. Every flavour I tried of this was not good but the effects made me forget about the bad taste real quick.. I found it gave a flushing effect like a niacin flush in the first 20 minutes, followed by an insane euphoria and floaty head high. The effects of this pre lasted a good 12-14 hours with no crash to note. The performance with regards to lifting was levelled up exponentially and every weight felt simply light, had to force myself to stop after almost 3 hours had elapsed. This at half dose so one scoop is pointless in my opinion and should only be consumed at the full dose as it doesn't contain any yohimbine so as the dose goes up the euphoria does without fat burner side effects. I would certainly recommend you get this legendary pre.

Crack Purple
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
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.

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.

Strongest thing I've ever taken
Hit within 20 mins, crazy tunnel focus. The yohimbine is no joke — started sweating 10 mins into my warm-up. Not for beginners. Energy lasted the full 2 hour session.

Taste is rough but the energy is real
Pina Colada flavor tastes more like chemicals but who cares. Pumps were solid and focus was dialed in. Wouldn't recommend for anyone under 180lbs.

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.

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.

Crack purple by Dark Labs
The infamous purple tub itself. Every flavour I tried of this was not good but the effects made me forget about the bad taste real quick.. I found it gave a flushing effect like a niacin flush in the first 20 minutes, followed by an insane euphoria and floaty head high. The effects of this pre lasted a good 12-14 hours with no crash to note. The performance with regards to lifting was levelled up exponentially and every weight felt simply light, had to force myself to stop after almost 3 hours had elapsed. This at half dose so one scoop is pointless in my opinion and should only be consumed at the full dose as it doesn't contain any yohimbine so as the dose goes up the euphoria does without fat burner side effects. I would certainly recommend you get this legendary pre.

Crack Purple
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
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.
