400mg dual-source caffeine with full-dose beta-alanine and patented pumps
Bucked Up MotherBucker is a straight-up, high-stim pre-workout that focuses on keeping your energy going, your mind sharp, and your endurance and pumps strong even after the initial rush. No fluff here—it's all transparent doses, solid amounts of key ingredients, and a smart setup that hits energy, blood flow, hydration, and fatigue all at once.
The big star is beta-alanine at 6,400mg. That's the top dose you see in studies. Beta-alanine boosts carnosine in your muscles, and carnosine fights off the acid buildup during intense workouts. It's great for repeated hard efforts lasting 1-10 minutes, where that burn usually kills your performance. Studies back 3.2-6.4g per day, so this is the real deal—not just a tiny amount. You'll feel tingles right away, and with regular use, you'll notice better staying power set after set.
For pumps, it's 4,000mg L-citrulline teamed with 1,500mg Nitrosigine®. Citrulline ramps up nitric oxide better than straight arginine, helping with blood flow and vasodilation. 4g is a good dose for performance, though not the max for pure pump products. Nitrosigine steps in as inositol-stabilized arginine silicate—it boosts arginine and nitric oxide, often giving a quicker, denser pump than citrulline by itself. Together, they make pumps smarter and more noticeable.
The energy and focus side is intense. You get 300mg caffeine anhydrous for quick kick-in plus 100mg microencapsulated delayed-relea
Bucked Up MotherBucker by Bucked Up contains 6400mg Beta-Alanine, a clinical dose for training performance and pump.
Key Highlights
- 6,400mg Beta-Alanine — that's a full max daily dose, way better than the weak 2-3g in a lot of pre-workouts. It boosts muscle carnosine to fight acid buildup, so you can push through those burning sets without fading fast.
- 4,000mg L-Citrulline — a solid dose for nitric oxide and blood flow, better than taking arginine straight. It's not the highest out there, but pairing it with 1,500mg Nitrosigine® makes it hit harder for pumps.
- 1,500mg Nitrosigine® — this patented arginine silicate is at the full dose you see in top formulas. It ramps up nitric oxide and blood flow, often giving you that immediate, tight pump feel that's missing in citrulline-only stuff.
- 400mg total caffeine from two sources — 300mg anhydrous for fast energy plus 100mg delayed-release to keep it going. This setup avoids the quick crash you get from one-shot caffeine bombs.
- 1,500mg L-Tyrosine — a hefty dose that helps make dopamine and norepinephrine, so you feel focused and steady even when tired. It's like cleaner drive during tough workouts.
- 300mg Alpha GPC — a real nootropic dose that boosts acetylcholine for better focus and mind-muscle link. Makes this feel like more than just a stim rush.
- 200mcg Huperzine A — this keeps acetylcholine from breaking down fast, stretching out the focus from Alpha GPC. Together, they make concentration last longer than caffeine alone.
- 2mg Rauwolscine — a strong alpha-2 blocker that adds edgy stim vibes beyond caffeine. That's why this feels like it's for pros, not newbies.

Who Is This For?
- Bodybuilders in volume phases wanting more than caffeine. 6.4g beta-alanine buffers burn in long sets, 4g citrulline plus 1.5g Nitrosigine® keep muscles full deep in.
- Seasoned users where 200-250mg caffeine does nothing. This hits 400mg dual caffeine, 2mg rauwolscine, 100mg theobromine—for those with real tolerance.
- CrossFitters needing drive and repeat power. Beta-alanine fits intervals, dual caffeine lasts through long workouts.
- Lifters who fade after 30 minutes. 300mg fast plus 100mg slow caffeine extends the energy.
- Athletes chasing better focus and connection. Alpha GPC, tyrosine, huperzine A boost concentration and output.
- Morning crew needing a kick plus performance. Replaces coffee with added pumps, hydration, endurance.
How to Use
Mix one scoop in 8-12 oz cold water and down it 20-30 minutes pre-workout. That lets the 300mg fast caffeine peak early, with 100mg slow-release carrying the end. New to high-stims? Start half-scoop—the 400mg caffeine and 2mg rauwolscine are no joke. Use a shaker for clumps from glycerol; cold water tastes better. Take on light stomach for quicker hit, or with food if tingles or caffeine bug you. No stacking with other stims like burners or big coffees. Pairs great with creatine, intra carbs, or electrolytes for big sessions. Cycle off sometimes for tolerance, but keep beta-alanine steady for best results. Store cool and dry to avoid clumps.
What to Expect
First 0-10 minutes: You start feeling alert, a warm buzz, and maybe beta-alanine tingles. 10-20 minutes: Fast caffeine hits full, tyrosine sharpens focus, and 6.4g beta-alanine tingles ramp up. 20-40 minutes: Sweet spot—stims, pumps from citrulline and Nitrosigine®, plus hydration from glycerol and sodium all click. 40-90 minutes: Slow caffeine keeps it steady, so you don't crash like with basic pres. Days 1-7: Energy and focus hit right away, but beta-alanine needs time to load carnosine. Weeks 2-4: Endurance shines as carnosine builds, helping you crush repeats and volume.

Frequently Asked Questions
How much caffeine is in Bucked Up MotherBucker Pre-Workout Anime per serving?
Each full scoop delivers 400mg total caffeine: 300mg from caffeine anhydrous for rapid onset and 100mg from microencapsulated delayed-release caffeine for a longer-lasting effect. That is firmly in high-stim territory and one reason this formula is better suited to experienced users.
Is the 6,400mg beta-alanine dose actually a clinical amount?
Yes. 6.4g is the top end of the evidence-based daily range commonly used in beta-alanine research. That dose is designed to raise muscle carnosine over time and improve performance in repeated high-intensity work, though it will also cause noticeable tingling in many users.
Why does this formula use both L-citrulline and Nitrosigine®?
They support nitric oxide and blood flow through related but not identical mechanisms. L-citrulline helps raise arginine availability systemically, while Nitrosigine® is a patented arginine-silicate complex designed to support nitric oxide and vascular response, creating a more complete pump profile together.
Is MotherBucker a good pre-workout for beginners?
Not really. Between 400mg total caffeine, 2mg rauwolscine, and 200mcg huperzine A, this is an advanced formula. New users should either start with 1/2 scoop very cautiously or choose a moderate-stim option instead.
What does the delayed-release caffeine actually do?
The 100mg microencapsulated caffeine is there to extend the stimulant curve after the 300mg caffeine anhydrous peaks. In practice, that helps the formula feel less front-loaded and more useful through longer sessions where standard pre-workouts tend to fade too early.
Can I stack this with creatine?
Yes, and it is a smart stack. MotherBucker does not include creatine, so adding 3-5g of standalone creatine monohydrate complements the formula well by supporting phosphocreatine regeneration while beta-alanine helps buffer acidity during repeated high-intensity efforts.
Why is there both Alpha GPC and huperzine A in this pre-workout?
Alpha GPC supplies choline to support acetylcholine production, while huperzine A slows acetylcholine breakdown. That combination is designed to make the focus and mind-muscle-connection side of the formula feel stronger and more sustained.
Will this make me tingle?
Very likely. The 6,400mg beta-alanine dose is high enough that many users will experience obvious paresthesia, especially on a relatively empty stomach. It is harmless for most healthy users, but it can feel intense if you are not used to it.
Should I take this every day or only on training days?
The stimulant side does not need daily use, but beta-alanine benefits most from consistency because muscle carnosine builds over time. Many users take it on training days only for stimulant control, while others use it daily if they specifically want to maximize beta-alanine loading.
Does this formula hide anything in a proprietary blend?
No. This is a fully transparent label with every major active listed and dosed. That is a major advantage in the high-stim category because you can evaluate the formula ingredient by ingredient without guessing what is actually inside.
