Two ways to boost nitric oxide with patented NO3-T® nitrates.
BlackMarket Labs Pump is a stim-free pre-workout that puts pumps first. It drives blood flow through different nitric oxide paths, boosts hydration inside your cells, and makes training feel better without caffeine faking the energy. That's key because top stim-free pump products aren't just watered-down versions of regular pres. They pack enough vasodilators—stuff that widens blood vessels—nitrates, osmolytes that help cells hold water, and electrolytes to really improve your session.
In a full 2-scoop serving, you get 4,000mg L-citrulline. That's a solid precursor to arginine that skips liver breakdown, turns into arginine in your kidneys, and fuels nitric oxide production for better blood flow. Studies show 6-8g is the sweet spot for performance, so 4g is under that but not alone here. It's teamed up with nitrates, which makes the whole formula click.
You get 1,000mg betaine nitrate and 500mg arginine nitrate, both as NO3-T®, a patented way to deliver nitrates from ThermoLife. Nitrates boost nitric oxide through their own path—nitrate to nitrite to NO—adding extra vasodilation beyond what citrulline does via arginine. This two-way attack is clever: citrulline handles arginine and clears waste like ammonia, while nitrates amp up blood flow, veins, and stamina. Using trademarked NO3-T® is a big deal—it's a high-end choice in a world where lots of labels skip it.
Betaine anhydrous is at 1,250mg. Research likes 2.5g a day best, so this is half that. By itself, it's okay, but the f

Key Highlights
- 4,000mg L-Citrulline per full serving leads the pack as a trusted nitric oxide booster. It turns into arginine easily and helps widen blood vessels through the arginine-NO path, giving you better flow and a pump you can really see and feel in the gym.
- 1,000mg Betaine Nitrate as NO3-T® brings in a second way to ramp up nitric oxide, not just relying on citrulline. Nitrates work through the nitrate-nitrite-NO route, making this feel like a step up from simple citrulline-only pump stuff.
- 500mg Arginine Nitrate as NO3-T® adds more nitrate-fueled blood flow. This builds a multi-angle approach for fuller muscles, popping veins, and pumps that last through tough workouts.
- Patented NO3-T® nitrates are a premium touch in pump products. These trademarked ingredients aren't just for show—they're a smart pick that sets real pump formulas apart from basic ones.
- 1,250mg Betaine Anhydrous helps with cell hydration and keeping your output strong by pulling in water. Studies show 2.5g daily is ideal, so this is a decent dose on its own, but it's smartly matched with betaine nitrate for extra betaine and better overall flow.
- 1,000mg L-Taurine hits the low end of what works in studies. It helps regulate water in cells, signals calcium, and supports nerve-muscle action, which can mean smoother lifts and better endurance in the gym.
- 250mg Pink Himalayan Salt boosts the hydration angle, not just focusing on nitric oxide. Sodium helps keep blood volume up, holds onto fluids when it counts, and improves how muscles contract, especially with taurine and betaine in the mix.
- BioPerine® at 2.5mg is a solid absorption helper from Sabinsa. It's lighter than the usual 5-10mg, but it shows the formula thinks about how well ingredients get taken up.

Who Is This For?
- Intermediate bodybuilders on push/pull/legs or classic splits chasing hypertrophy who want lasting pumps, full muscles, and smooth training. 4g L-citrulline, NO3-T® nitrates, taurine, and sodium make high-rep work feel strong without stim hype.
- Late-day lifters needing real pre effects without sleep killers. Stim-free means blood flow, hydration, and quality sessions at night without caffeine hanging around.
- Folks using coffee, energy drinks, or separate stim pres who control their stim load. It works standalone or stacked, with dedicated pump and hydration actives.
- Lifters who feel flat even with carbs. Taurine, betaine, nitrates, and salt boost cell water and blood volume for fuller muscles and better lifts.
- Pump chasers who know multi-path NO is better than one ingredient. It mixes citrulline arginine support with nitrate NO for a smarter setup than basic ones.
- People easing off high-stim pres but keeping workouts solid. This maintains the pre ritual and support while resting your system from heavy caffeine.
How to Use
Mix 1 scoop in 10-12 oz water or 2 scoops in 16-24 oz, drink 20-30 minutes before lifting. That lines up citrulline, nitrates, taurine, and hydration for your first big sets. If nitrates are new, start with 1 scoop to test your gut, then bump to 2. Use a shaker for even mix, add more water for milder taste or extra hydration. Empty stomach speeds it up, but if powders hit hard, eat some carbs 60-90 minutes before to smooth it out. Stim-free means you can add coffee or stims, but pumps pop best with dialed hydration and carbs. No stim tolerance, so no cycling needed. Keep it sealed cool and dry for best scoop and taste.
What to Expect
First 0-10 minutes, it's pure stim-free: no rush, no spike, just a tasty drink starting your routine. 10-20 minutes in, you start feeling the workout lock in with easier warm-ups, muscles getting fuller, and early blood flow instead of nerves firing. 20-40 minutes is prime time, where citrulline, NO3-T® nitrates, taurine, and sodium deliver big pumps, veins, and connected reps. 40-90 minutes, it holds steady without stim crashes. Days 1-7, it's all about that session feel. Weeks 2-4, steady use with taurine and betaine's hydration can make workouts more consistent, especially with good carbs and water.

Frequently Asked Questions
Does BlackMarket Pump contain caffeine or other stimulants?
No. This is a stimulant-free pre-workout built around blood flow, hydration, and training feel, with key actives including 4,000mg L-citrulline, NO3-T® nitrates, 1,000mg taurine, and 1,250mg betaine anhydrous.
What is the difference between 1 scoop and 2 scoops?
The label is structured as 1 scoop or 2 scoops, with the full active panel provided at 2 scoops. That means 1 scoop is best treated as a lighter introductory serving, while 2 scoops is the intended full-performance dose for the complete pump and hydration effect.
Is 4g of citrulline enough for a pump pre-workout?
On its own, 4g is below the classic 6-8g research range often cited for standalone L-citrulline. In this formula, however, citrulline is intentionally paired with nitrate ingredients—1,000mg betaine nitrate and 500mg arginine nitrate as NO3-T®—so the pump strategy is broader than citrulline alone.
What do the NO3-T® ingredients actually do?
NO3-T® is ThermoLife's patented nitrate ingredient platform used here for betaine nitrate and arginine nitrate. Nitrates support nitric oxide production through the nitrate-nitrite-NO pathway, which complements citrulline's arginine-based pathway for a more layered blood-flow effect.
Can I stack BlackMarket Pump with a caffeinated pre-workout?
Yes, many experienced users will use a pump product like this alongside separate caffeine or a stimulant pre. Because Pump has no caffeine, it is flexible; just pay attention to total stimulant intake from whatever you add on top.
Is this better for bodybuilding workouts or strength-focused sessions?
It is strongest for hypertrophy and high-volume sessions where pump, blood flow, and mind-muscle connection matter most. That said, better hydration support and blood delivery can still improve the feel of strength sessions, especially on assistance work.
Will I feel this immediately if it has no stimulants?
Yes, but the effect is different from a caffeine pre-workout. Instead of a mental jolt, most users notice fuller muscles, improved vascularity, and a smoother, more connected training feel as the session progresses.
What does taurine add to this formula?
At 1,000mg, taurine supports osmoregulation, calcium signaling, and muscular endurance. In practical terms, it helps the workout feel smoother and better hydrated, especially when combined with sodium and betaine.
Does BioPerine® matter at 2.5mg?
BioPerine® is a clinically studied black pepper extract used to support bioavailability, but 2.5mg is lighter than the more common 5-10mg range seen in research and finished formulas. It is a useful inclusion, just not one of the primary performance drivers here.
Who should use 1 scoop instead of 2 scoops?
Start with 1 scoop if you are new to nitrate-based pump formulas, have a sensitive stomach, or want a lighter stack with another pre-workout. Use 2 scoops when you want the full intended nitric oxide and hydration effect from the formula.
