325mg caffeine with 1g Nitrosigine® for high-stim pump performance

GAT Nitraflex Black Extreme is a high-stim pre-workout that's simple and focused. It gives you quick energy, patented nitric oxide help, and basic support for intense workouts. No proprietary blends here. Everything is listed out, so you can check the doses against real studies.

The main energy comes from 325mg caffeine. That's in the sweet spot of 200-400mg that shows up in pre-workout research. Caffeine blocks adenosine receptors in your brain, which cuts down on feeling tired and boosts stuff like dopamine and norepinephrine. In the gym, you notice quicker focus, more drive, better alertness between sets, and the push to go harder when it gets tough. At 325mg, it's a solid high-stim hit, especially if you're under 180 pounds or don't do caffeine every day.

For pumps and blood flow, it's got 1,000mg Nitrosigine®. That's bonded arginine silicate, a patented version that's better at boosting nitric oxide than regular arginine. The dose matters—1 gram is what studies use for better vasodilation, blood flow, and that workout pump. It raises arginine and nitric oxide levels, improving how blood vessels respond and getting nutrients to your muscles. You'll feel fuller muscles, stronger pumps, and more veins popping during sets.

Beta-alanine is included at 1,500mg. This amino acid is the rate-limitin

Key Highlights

• 325mg Caffeine — a solid high-stim dose right in the researched range for sports supps. You get clear energy, sharp alertness, and the motivation to crush heavy or high-volume workouts.
• 1,000mg Nitrosigine® — not cheap arginine, but the patented bonded arginine silicate from Nutrition21. This 1-gram dose is what studies back for nitric oxide boosts, wider blood vessels, better flow, and the full pumps that make good pre-workouts stand out from basic stim mixes.
• Fully disclosed formula — every ingredient and dose is right there, no hidden blends. You can compare it to real research instead of wondering what's actually working.
• Beta-alanine at 1,500mg — helps build muscle carnosine for handling repeated hard efforts. It's under the full 3.2g daily mark from studies, so it's solid support but not the whole deal on its own.
• Research-backed caffeine dosing — caffeine is one of the best-proven boosts in supps. It blocks adenosine receptors, and you feel more alert, less tired, and ready to train hard. Super reliable.
• Premium pump in a simple setup — lots of basic pre-workouts are just caffeine with no blood flow help. Nitrosigine® adds that muscle feel, making workouts better beyond just the head buzz.
• No label junk — this is targeted, not a list of hype. Easy to stack with your own creatine, electrolytes, or carbs based on what you need.
• Built for noticeable onset — simple formula means you feel it clearly. Caffeine kicks in with focus first, then pumps build as you hit sets.

Who Is This For?

• Experienced lifters wanting a strong kick without a huge ingredient list. 325mg caffeine surges you, 1,000mg Nitrosigine® adds premium flow over basic stims.
• Bodybuilders chasing hypertrophy with visible pumps and mind-muscle link in volume sessions. Nitrosigine® boosts nitric oxide and vessels for fuller, engorged muscles.
• Intermediate folks on push/pull/legs or upper/lower who like simple, clear formulas. Four open ingredients, no blends—perfect if you value knowing what's in it.
• Athletes in build phases with supersets and short rests. 1,500mg beta-alanine helps carnosine loading for acid buffering in intense work.
• Tired of hyped labels with tiny doses? This focuses on strong caffeine, patented nitric oxide, and a clear setup you can check against studies.
• Morning or early trainers needing big stim and focus. 325mg suits those who want to feel it hit hard, not soft energy.

How to Use

Try half a serving first if you're new to over 300mg caffeine—this is real high-stim. Most can go full serving 20-30 minutes pre-train for peak timing. Mix in 10-16 oz cold water, shaker style; more water mellows flavor, less amps it. Empty stomach for strongest hit, light meal if you want slower. Don't add extra caffeine like coffee or burners unless you handle a lot. Pairs well with creatine, electrolytes, or intra carbs. No need to cycle for safety, but breaks from caffeine can refresh the feel. Keep it sealed, cool, and dry.

What to Expect

Minutes 0-10: not much yet, just getting set, especially with food. Minutes 10-20: caffeine shows up with alertness, sharpness, and dropping laziness; maybe some beta-alanine tingle. Minutes 20-40: full caffeine engagement, Nitrosigine® pumps and veins popping in sets. Minutes 40-90: energy holds, pumps peak in volume parts. Days 1-7: main hits are stim and blood flow. Weeks 2-4: beta-alanine builds carnosine, boosting high-intensity support beyond day one.
