BlackMarket Labs BULK is the brand's flagship muscle-building pre-workout — the product that established BlackMarket's identity in the supplement market. Built around five core performance goals simultaneously: energy (300mg Caffeine Anhydrous), muscular endurance (3.2g Beta-Alanine), strength and power (3g Creatine Monohydrate, Betaine Anhydrous), pump and blood flow (Agmatine Sulfate), and testosterone and male vitality support (1.5g D-Aspartic Acid, Mucuna L-Dopa). AstraGin 50mg for absorption optimization. Zero sugar. No artificial dyes. Third-party tested for quality, safety, and purity. Made in the USA. 30 servings. Six flavors. Athlete Disclosure applies — contains Synephrine (Bitter Orange Extract), which is prohibited by some athletic organizations. California Prop 65 Warning applies.†
The supplement market has two dominant pre-workout categories: pure energy products that deliver stimulants and pump ingredients with nothing else, and muscle-building products that include creatine and performance compounds alongside stimulants. BULK sits firmly in the second category — and adds a third dimension that almost no other pre-workout touches at all: natural testosterone support. The inclusion of 1.5g of D-Aspartic Acid and Mucuna L-Dopa in a pre-workout formula creates a genuine 2-in-1 product that addresses the training session itself (energy, endurance, pump, strength) and the hormonal environment around training simultaneously.†
The clinical dose of Beta-Alanine for carnosine loading is 3.2g daily — the dose documented in the research that established Beta-Alanine's effects on intra-workout endurance and lactate buffering. Most pre-workouts include Beta-Alanine at 1.5-2g — functional, but below the dose where the research consistently shows meaningful carnosine saturation. BULK includes 3.2g per scoop — the full clinical dose — producing the characteristic Beta-Alanine paresthesia (harmless tingling) that many users associate with the product working. This dose differentiation between BULK and under-dosed competitors is one of the formulation decisions that has kept BULK in the market for years.†
Three grams of Creatine Monohydrate per pre-workout serving is designed to contribute toward the 3-5g daily maintenance dose without requiring a separate standalone creatine supplement. For users taking BULK daily, the cumulative creatine contribution is meaningful — 3g per training day adds up over a training week to a total intake that, combined with dietary creatine from protein sources, keeps muscle creatine stores in a positive state. Users who want to maximize creatine saturation can supplement an additional 2-3g of standalone creatine on training days or 5g on rest days alongside BULK.†
D-Aspartic Acid at 1.5g brings the LH-stimulating, testosterone-supporting amino acid into the pre-workout context. Pre-workout timing for DAA is not the conventional DAA supplementation window (DAA is typically taken morning or evening for hormonal optimization), but its inclusion in BULK means users who take BULK consistently are getting 1.5g of DAA daily without needing to add a separate testosterone support supplement to their stack. This is BULK's key point of differentiation versus standard pre-workouts — it addresses testosterone support in the same serving, making it particularly relevant for men over 30 who want energy and performance support alongside natural hormonal optimization from a single product.†
Synephrine is a sympathomimetic alkaloid from Citrus aurantium (Bitter Orange) that acts as a beta-2 and beta-3 adrenergic receptor agonist — stimulating thermogenesis, fat oxidation, and energy expenditure through mechanisms distinct from caffeine's adenosine receptor antagonism. In combination with caffeine, Synephrine produces a synergistic thermogenic and energy effect — the two compounds potentiate each other's stimulant effects through complementary receptor pathways. Synephrine is prohibited by the NCAA and some other athletic governing bodies. All competitive and tested athletes must consult their specific governing body's prohibited substance list before using BULK.†
Mix 1 scoop with 10-12oz of cold water. Consume 15-45 minutes before training. New users: start with half scoop to assess stimulant tolerance. Do not exceed 1 serving in a 24-hour period. Do not combine with other stimulant-containing products. Avoid within 5-6 hours of bedtime. Not for persons under 18. Not for pregnant or nursing women. Athlete Disclosure — contains Synephrine. California Prop 65 Warning applies.†

"Great product"
"I use a few different pre workouts and like to mix a little of each one. I really like the way Bulk makes me feel. The creatine in it really seems to make me feel a good swell. It also keeps me going all out in the gym."
