6g Citrulline, 200mg Caffeine, AlphaSize® Focus—Fully Disclosed
Bucked UP | IV is a solid moderate-stim pre-workout that hits on energy, blood flow, and pushing through tough sessions. It keeps things simple: 6,000mg citrulline malate leads for nitric oxide and pumps, 200mg caffeine anhydrous handles the energy side, AlphaSize® adds focus, and then you've got beta-alanine, some electrolytes, taurine, ActiGin®, methylcobalamin B12, and deer antler velvet extract to round it out. It's not jammed with everything under the sun, and it's not just a basic stim. It's right in the middle—enough to make a difference, and easy to read.
The star here is the 6,000mg citrulline malate. Your body turns citrulline into arginine, which boosts nitric oxide—that's what opens up blood vessels for better flow and those satisfying pumps. At 6g, it's a real dose that helps with performance and cuts down on fatigue during back-to-back efforts. This isn't some weak amount just for show.
Beta-alanine is in at 2,000mg. It helps make carnosine in your muscles, which fights off the acid build-up that causes that burn during intense sets. Studies back it for high-intensity stuff lasting 1-10 minutes. Real talk: 2g is decent, but most research uses 3.2-6.4g. You'll still get carnosine building over time, but this alone isn't hitting the full daily load from studies.
Caffeine anhydrous
Key Highlights
- 6,000mg Citrulline Malate — this is the big one in the formula, a strong dose that really delivers on nitric oxide, wider blood vessels, and those full pumps that weak 3g versions can't match.
- 200mg Caffeine Anhydrous — solid moderate energy that perks you up, boosts drive, and gets you ready without jumping to that intense 300-400mg level. For a lot of folks, this hits just right—energized but not wired.
- 200mg AlphaSize® — branded alpha-GPC that actually helps with focus and connecting to your lifts, not just thrown in for looks. It's great when you want your workout to feel sharp and on-point from start to finish.
- 2,000mg Beta-Alanine — here for building carnosine to buffer fatigue in those burning sets. The science is solid for intense training, but heads up, 2g is helpful but under the usual 3.2g from studies.
- Fully disclosed label — everything's listed out with doses, no hidden prop blends. That's huge because you can check it against what works instead of wondering what's in some fancy blend.
- Vitamin B12 as methylcobalamin — the active form at 100mcg. It supports your energy systems, especially if you're looking for more than just a caffeine buzz in your pre.
- AlphaSize® plus caffeine synergy — caffeine ramps up your drive, AlphaSize® helps with brain signaling. Together, it's energy that feels directed and useful for gym tasks, not just hype.
- Pump-plus-performance positioning — more than caffeine with flavor. Citrulline brings the blood flow, beta-alanine fights muscle fatigue, making your whole workout feel better than energy alone.
Who Is This For?
- Intermediate lifters on hypertrophy plans who want real pumps and enough energy for volume without huge 350mg+ caffeine. 6g citrulline malate delivers flow and feel, 200mg caffeine keeps it energetic but chill.
- Bodybuilders focusing on isolation and mind-muscle—AlphaSize® at 200mg adds sharp focus that works with citrulline's blood flow for chest, shoulders, arms, legs.
- Morning trainers needing a wake-up without blowing daily caffeine limits. 200mg anhydrous gives a good boost with room for later coffee.
- Folks in high-rep accumulation phases where burn and fade hit hard. Beta-alanine builds buffering over time, caffeine maintains push through sessions.
- Rec athletes wanting a balanced pre that's not extreme. It covers energy, focus, flow, and support in an easy-to-get label.
- Upgrading from basic caffeine pres to something fuller. This brings solid citrulline and AlphaSize® with moderate stims for most users.
How to Use
Take one full serving 20-30 minutes pre-workout. That lets caffeine hit and pump/focus build before real sets. If you're new or stim-sensitive, try half first, especially with other caffeine that day. Shake it in 10-16 oz cold water—more water tones down flavor. It hits faster on a light stomach, but a small meal can ease tingles if beta-alanine bugs you. Don't stack with heavy stim stuff unless you're tracking total caffeine. Adding creatine monohydrate pairs great for ATP support alongside beta-alanine's buffering. No need to cycle non-stims, but occasional caffeine breaks keep things fresh if you're a frequent user. Keep it sealed cool and dry for best powder quality.
What to Expect
Minutes 0-10: mix and sip—it goes down easy like most pres, no heavy carb feel. Minutes 10-20: caffeine kicks in with better alertness, and you might get light beta-alanine tingles. Minutes 20-40: prime time for lifts, where energy peaks and AlphaSize® plus caffeine make focus feel strong. Minutes 30-60: citrulline malate shows in pumps, veins, and muscle fullness as you go. Minutes 60-90: energy holds steady without a hard drop thanks to the moderate dose—your tolerance and food play in. Days 1-7: you'll notice energy, focus, pumps most. Weeks 2-4: beta-alanine steps up as carnosine builds, making tough sets handle better.
Frequently Asked Questions
How much caffeine is in Bucked UP | IV per serving?
Each full serving provides 200mg caffeine anhydrous. That places it in the moderate-stim range: enough to noticeably improve alertness and training drive, but below the 300-400mg levels used in many aggressive pre-workouts.
Is the 6,000mg citrulline malate dose actually effective?
Yes. 6g citrulline malate is a legitimate performance dose and one of the strongest parts of the formula. Citrulline increases arginine availability and nitric oxide production, which supports vasodilation, blood flow, and the fuller pump most users are looking for in a pre-workout.
Why is beta-alanine included at 2,000mg instead of 3,200mg?
Beta-alanine works by increasing muscle carnosine over time, and the most commonly studied daily range is 3.2-6.4g. At 2g, Bucked UP | IV still contributes to carnosine loading, but it falls short of the classic full clinical benchmark, so dedicated users may want additional standalone beta-alanine if they want research-level daily intake.
What does AlphaSize® do in this formula?
AlphaSize® is a branded alpha-GPC ingredient included at 200mg for focus and mind-muscle connection. It supplies choline, which supports acetylcholine production, helping the workout feel more mentally engaged and coordinated rather than just stimulated.
Will this pre-workout make me tingle?
It can. The formula contains 2,000mg beta-alanine, which can cause the temporary tingling sensation known as paresthesia, especially on an emptier stomach. It is harmless for most users and tends to be more of a sensation cue than a measure of product quality.
Can I stack Bucked UP | IV with creatine?
Yes, and it is one of the best stacks for this product. Bucked UP | IV covers energy, pump, and some endurance support, while a separate 3-5g daily creatine monohydrate product adds phosphocreatine support for strength, power, and training volume.
Is this a good pre-workout for beginners?
For many beginners, yes—provided they start with a half serving. The 200mg caffeine dose is meaningful, and the formula is transparent and not overloaded, which makes it easier to learn how your body responds compared with higher-stim pre-workouts.
How long before training should I take Bucked UP | IV?
Most users do best taking it 20-30 minutes before training. That timing allows caffeine uptake to begin and gives the formula’s focus effects time to build before your first heavy or high-volume working sets.
Is this more of a pump product or an energy product?
It is balanced, but the two strongest identities are moderate energy and real pump support. The caffeine gives it a reliable pre-workout backbone, while the 6g citrulline malate dose is strong enough to make pump a genuine part of the experience rather than a marketing afterthought.
Does Bucked UP | IV use any proprietary blends?
No. The formula is fully disclosed, which means every active ingredient and every dose is listed on the label. That is a major advantage in a category where many products still hide behind proprietary blends.
