Crack Gold Pre-Workout – Key Ingredients Breakdown (Per Serving)



  • L-Citrulline – 5000mg A non-essential amino acid involved in the urea cycle and frequently used in sports supplements to support circulation and nutrient transport by acting as a precursor to nitric oxide.

  • Beta-Alanine – 2000mg This beta amino acid contributes to the production of carnosine in muscle tissue. Carnosine acts as a buffer for hydrogen ions, helping to maintain pH balance during prolonged exertion.

  • Agmatine Sulfate – 1000mg A derivative of arginine that is often found in nitric oxide support formulas. It is suggested to have neuromodulatory and metabolic effects.

  • L-Tyrosine – 750mg A non-essential amino acid and precursor to catecholamines, including dopamine, epinephrine, and norepinephrine. Often included in pre-workouts to support cognitive readiness.

  • Alpha GPC 50% (Alpha-Glycerylphosphorylcholine) – 500mg A choline-containing compound included in nootropic blends. It is known to support the production of acetylcholine, a neurotransmitter associated with attention and neuromuscular communication.

  • Caffeine Anhydrous – 300mg A widely used central nervous system stimulant that enhances alertness and wakefulness. Caffeine anhydrous is a dehydrated, fast-acting form commonly used in sports nutrition.

  • N-Phenethyldimethylamine Citrate – 300mg A compound structurally related to phenethylamines. Often used in focus and stimulant blends in advanced formulas.

  • 2-Aminoisoheptane – 250mg Also known as 2-amino, this aliphatic amine is found in specific plant sources and is used in high-stim pre-workouts for its sensory impact and energising profile.

  • Caffeine Citrate – 200mg A combination of caffeine and citric acid, it is known for its fast absorption and smoother onset. It is often used alongside caffeine anhydrous to create a multi-phase caffeine delivery system.

  • Halostachine – 50mg A naturally occurring compound considered to have adrenergic activity. Found in some fat-burning and stimulant-based pre-workouts.

  • Alpha Yohimbine 90% (Rauwolscine – Rauwolfia vomitoria root) – 1.5mg A plant-derived alkaloid structurally similar to yohimbine. Frequently included in high-stim products targeting intensity and mental drive.

Dark Labs Crack Gold Edition is a limited-edition high-stimulant pre-workout designed for experienced users. It combines amino acids, nootropics, and multiple stimulant compounds to support intense training performance across 25 servings.

The formula includes Caffeine Anhydrous, Di-Caffeine Malate, Halostachine, and Alpha Yohimbine (Rauwolscine). This multi-stimulant stack is intended to deliver layered energy and mental drive throughout your session.

L-Citrulline (5000mg) and Agmatine Sulfate (1000mg) form the nitric oxide support base of this formula. L-Citrulline serves as a precursor to nitric oxide, while Agmatine Sulfate has neuromodulatory and metabolic properties.

Crack Gold Edition includes L-Tyrosine (750mg) and Alpha GPC 50% to support cognitive readiness and mental focus. L-Tyrosine is a precursor to catecholamines including dopamine and norepinephrine.

Beta-Alanine (2000mg) contributes to the production of carnosine in muscle tissue, which acts as a buffer for hydrogen ions during prolonged exertion. It may cause a harmless tingling sensation known as paraesthesia.

The formula is designed to support energy, mental focus, pump, and training intensity simultaneously. Its layered stimulant profile and nootropic additions make it suitable for multi-dimensional pre-workout preparation.

Follow the serving guidelines on the label, starting with a half serving to assess tolerance due to the high-stimulant content. Do not exceed the recommended dose and avoid combining with other stimulant-containing products.

No — this product is formulated for experienced users already accustomed to advanced high-stimulant pre-workouts. Beginners should start with lower-stimulant formulas before considering Crack Gold Edition.

Yes, Crack Gold Edition is stimulant-heavy and contains no carbohydrates, making it compatible with a cutting phase. The inclusion of Alpha Yohimbine makes it a common choice for users in a caloric deficit.
