Quick answer: The Dark Labs Crack range has eight pre-workouts across three intensity tiers. Crack Initiation and Crack Daily sit at the lighter end and suit regular training days. Crack Purple and Crack Reloaded are high-stim. Crack OG, Crack Gold, Crack Diamond and Crack Barbarian are the extreme tier. Both stimulant-heavy tiers are for experienced users only. Below, we compare every formula side by side so you can pick the right one for how you train.
The Crack Range at a Glance
Every figure below comes from the product's current supplement facts panel. Caffeine shows caffeine anhydrous only: most Crack formulas add other caffeine forms on top, so always check the total caffeine declared on your tub.
| Formula | Stim level | L-Citrulline | Beta-Alanine | Caffeine anhydrous | Standout ingredients | Servings |
|---|---|---|---|---|---|---|
 Crack Initiation |
Smooth | 6 g | 3.2 g | None (zümXR® + green coffee) | Betaine, HydroPrime®, CognatiQ® | 30 |
 Crack Daily |
Medium | 5 g | 4 g | 300 mg | HydroPrime™ 2.5 g, L-Tyrosine | 30 |
 Crack Purple |
High | 4 g per scoop | 1.5 g per scoop | 200 mg per scoop | Agmatine, Choline | 40 scoops |
 Crack Reloaded |
High | See supplement facts panel | HydroPrime®, ZumXR®, CognatiQ® | 40 | ||
 Crack OG |
Extreme | 8 g (2 scoops) | 3.2 g (2 scoops) | 400 mg (2 scoops) | Agmatine, L-Arginine, L-Norvaline | 40 scoops |
 Crack Gold |
Extreme | 5 g | 2 g | 300 mg | Alpha GPC, L-Tyrosine | 25 |

Smooth and Medium: The Lighter Side of Crack
Crack Initiation: The Smooth-Energy Option
Crack Initiation takes a different route to energy. Instead of caffeine anhydrous, it pairs green coffee bean extract with zümXR® extended-release caffeine. Around that sit 6 g L-citrulline, 3.2 g beta-alanine, 2 g betaine and four branded ingredients: HydroPrime®, CognatiQ®, zümXR® and AstraGin®.
Choose Initiation if you want the Crack attitude with a smoother energy profile, or you are moving up from standard pre-workouts. It is still a caffeinated product, not a stimulant-free one.
Crack Daily: Built for the Sessions You Repeat
Crack Daily is the medium-stim, everyday member of the family. Each serving lists 5 g L-citrulline, 4 g beta-alanine, 2.5 g HydroPrime™ glycerol powder and 1.5 g L-tyrosine. Three caffeine forms (anhydrous, di-caffeine malate and citrate) make up the energy side, with no proprietary blends.
Choose Daily if you train four or five times a week and want a substantial formula without reaching for the most extreme Crack every session.
High-Stim: Crack Purple and Crack Reloaded
Crack Purple: The Cult Classic
Crack Purple is one of the best-known names in the range. One scoop lists 4 g L-citrulline, 1.5 g beta-alanine, 500 mg agmatine sulfate and 250 mg choline bitartrate, with 200 mg caffeine anhydrous plus caffeine citrate and other stimulant ingredients. The current suggested use is one scoop.
Choose Purple if you want a stacked stimulant profile with a dosing format you can control scoop by scoop.
Crack Reloaded: Three Caffeine Sources, Three Branded Ingredients
Crack Reloaded combines caffeine anhydrous, ZumXR® and caffeine citrate with HydroPrime®, CognatiQ®, L-tyrosine and choline bitartrate. It brings branded ingredients usually found in the lighter Crack formulas into a high-stim product. Check the supplement facts image on the product page for amounts per serving.
Choose Reloaded if you want high-stim intensity with a broader ingredient profile than caffeine alone. 40 servings per tub.
Extreme: OG, Gold, Diamond and Barbarian
These four sit at the top of the Crack range. Each combines multiple caffeine forms with additional stimulant ingredients, so they are strictly for experienced high-stim users. Start with half a serving to assess your tolerance.
Crack OG: The Formula That Built the Name
Crack OG is the most recognisable Dark Labs pre-workout. A full serving is two scoops and lists 8 g L-citrulline, 3.2 g beta-alanine, 1 g agmatine sulfate, 1 g L-arginine HCl and 250 mg L-norvaline. On the stimulant side, 400 mg caffeine anhydrous sits alongside caffeine citrate, dicaffeine malate and further stimulant ingredients.
Choose OG if you want the original extreme Crack and the biggest citrulline dose in the range. Start with one scoop.
Crack Gold Limited Edition
Crack Gold is a one-scoop, 14.1 g serving with 5 g L-citrulline, 2 g beta-alanine, 1 g agmatine sulfate, 750 mg L-tyrosine and 500 mg Alpha GPC 50%. Its stimulant matrix includes 300 mg caffeine anhydrous and 200 mg caffeine citrate.
Choose Gold if you want an extreme formula with a focus-oriented side from L-tyrosine and Alpha GPC. As a limited edition, availability can change.
Crack Diamond Edition
Crack Diamond pairs two equal headline doses: 5 g L-citrulline and 5 g beta-alanine. It also lists 1 g agmatine sulfate, 1 g L-tyrosine, 75 mg kanna extract and 15 mg BioPerine®, with 350 mg caffeine anhydrous among three caffeine forms.
Choose Diamond if you want the highest beta-alanine dose in the range alongside a complex stimulant profile.
Crack Barbarian Edition
Crack Barbarian has the largest agmatine dose in the range at 1.5 g. A full 17.6 g scoop also lists 6 g L-citrulline, 3.2 g beta-alanine, 1 g L-tyrosine and 500 mg Alpha GPC 50%, with 350 mg caffeine anhydrous among three caffeine forms.
Choose Barbarian if you want the most pump-focused extreme Crack.
How to Choose Your Crack
- New to the Crack range: start with Initiation or Daily.
- Training most days of the week: Daily was designed for exactly that.
- Ready for high-stim: Crack Purple or Crack Reloaded.
- Want the most intense Crack: the extreme tier, starting with the original Crack OG.
- Pump is your priority: Barbarian (6 g citrulline, 1.5 g agmatine) or a full two-scoop serving of OG (8 g citrulline).
- Focus matters as much as energy: Gold or Barbarian, both with L-tyrosine and Alpha GPC.
- Training late in the evening: skip stimulants and look at our stim-free pre-workouts, such as P.I.M.P. or Maniaco Pump.
Build Around Your Crack
None of the Crack formulas list creatine. If you use it, add a separate product such as Dark Labs Creatine 500 g or Alpha Creatine. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise.

Crack Range FAQ
Which Crack pre-workout is the strongest?
Crack OG, Gold, Diamond and Barbarian form the extreme tier. A full two-scoop serving of Crack OG lists 400 mg caffeine anhydrous, the highest figure in the range. Total stimulant load depends on the full formula, so compare the labels rather than one number.
What is the difference between high-stim and extreme?
Crack Purple and Crack Reloaded are high-stim formulas. The extreme tier adds larger caffeine doses and broader stimulant profiles per full serving. Both tiers are for experienced users only.
Which Crack is best for beginners?
None of the high-stim or extreme editions are for beginners. If you are new to the range, start with Crack Initiation or Crack Daily, and begin with half a serving to assess your tolerance.
Can I add up the caffeine forms to get total caffeine?
No. Di-caffeine malate and caffeine citrate weigh more than the caffeine they contain. Use the total caffeine declared on your tub.
Can I take two Crack pre-workouts together?
No. Do not combine any Crack formula with another stimulant pre-workout, energy drink or extra caffeine.
Are Crack products sold at Dark Labs UK genuine?
Yes. Dark Labs UK is the official Dark Labs store for the United Kingdom, and every product we sell is 100% genuine.
