Dark Labs Crack OG Pre Workout Review + Best Deal 2026

Written by TJ, Fitness Deal News | 10+ Years of Reviewing Supplements

Dark Labs, top of the stim junkie mountain, and they’ve called this one Crack the OG. It isn’t the OG.

The original Crack ran on DM**, and this is a DMHA formula with a lot of other stimulants around it.

The tub is also way louder than the usual Dark Labs look, which tends to be more subtle.

I love it, and it looks great on a shelf.

The Label: What’s Inside Crack OG

Labels are just labels, but here it is. The full serving is two scoops (20g), and that’s how I ran it.

Pump side:

• L-Citrulline – 8g
• Agmatine – 1g
• L-Arginine – 1g
• Beta-Alanine – 3.2g (head buzz and tingles, no complaints)

Stimulant side:

• Caffeine: 650mg total from three sources (anhydrous, caffeine citrate at 150mg, dicaffeine malate at 100mg)
• Eria Jarensis – 400mg (focus and mood)
• DMHA – 300mg (head buzz)
• Isopropylnorsynephrine – 30mg
• Noopept (the bubble-head focus)
• Alpha Yohimbine – 1.5mg

For a Dark Labs stim junkie pre, that’s a solid pump formula, and the stimulant stack means business.

Don’t get hypnotized by the DMHA number, though. Some of my happiest, most euphoric workouts came from 150 to 200mg of good DMHA.

Quality and purity matter more than the milligrams on the tub, and the same goes for the alpha yo. 1.5mg doesn’t sound like much, but it hits harder or softer depending on the purity.

My Experience: Does It Deliver?

1. Flavor

It comes in Very Dark Berry and four other flavors. I ran Very Dark Berry, and it’s a solid flavor that’s very similar to the original Crack. Whatever you think of flavors, this is not the pre-workout you buy for flavor.

2. Onset

This is what sets it apart from the other Cracks and most of the Dark Labs lineup. Everything hits at once.

Within 10 minutes I had the beta-alanine tingles, the caffeine kick, the head buzz and the focus bubble, and by 20 minutes it was all in place.

Flame V1 was pure euphoria, with no beta-alanine and barely any alpha yo.

This one shows up all at the same time.

3. Mood and Focus

Aggressive euphoria is the best way I can put it.

It’s not the dancing-in-the-kitchen kind. It’s Metallica’s “Enter Sandman” playing in your head.

It’s not full thrash metal, but you’re clearly aggressive and going at it. T

he DMHA, Eria and Noopept come together for a high-pressure, bubble-head focus where everything outside the workout fades out.

4. Energy and Stim Effects

The energy is intense and aggressive. The alpha yo feels like more than 1.5mg.

Expect some heart racing and a few side effects, nothing crazy and never unproductive, but you’ll feel it.

This is a stim junkie experience.

It also lasts. I took it in the morning and still felt it six or seven hours later. If you want to sleep before 3am, do not take this at 8pm.

5. Pumps

Solid for a Dark Labs stim pre. The 8g of citrulline plus agmatine and arginine does its job.

The Final Verdict

Crack the OG is an aggressive-euphoria stim pre-workout. It hits fast, hits hard and doesn’t let go.

If you know the Dark Labs universe, it doesn’t sit where you’d expect. I

t’s a different animal from the original DM** Crack and from the Flame family (V1 was pure euphoria, V2 was too aggressive, and V3 lands in between).

If you’re a stim junkie who wants a long, loud, aggressive ride with real pumps, Dark Labs nailed it.

If you’re stim-sensitive or new to DMHA and alpha yo, skip this one.
