6g Citrulline, 200mg Caffeine, Straight-Up Performance Formula
Bucked Up nailed a solid middle-ground pre-workout here: not a crazy stim bomb, not just pumps, and not overloaded with everything. They focus on a real pump dose, enough energy to get you going, some brain and performance helpers, and a totally open label so you know what you're getting. No shady prop blends like some others.
The star is 6,000mg citrulline malate. That's the amount serious lifters want because citrulline boosts arginine levels better than arginine alone, which ramps up nitric oxide for wider blood vessels. In the gym, you feel better blood flow, bigger pumps, and more oxygen and nutrients hitting your muscles. This makes it way better than basic pre-workouts that skimp with only 3-4g.
Beta-alanine comes in at 2,000mg. It helps make carnosine, which buffers acid in your muscles to fight that deep burn during tough sets. Studies show 3,200-6,400mg daily is ideal, so 2g is a bit light. It can still help over time, especially if you get more from other supps, but it's not a full dose on its own. Real talk: it's decent, but not maxed out like the research suggests.
Caffeine anhydrous is at 200mg, keeping things moderate. You get a good bump in alertness, drive, and energy without tipping into high-stim chaos. For a lot of people, this is just right—feels strong but easy to handle day after day. Vitamin B12 is
Key Highlights
- 6,000mg Citrulline Malate — this is the real deal for pumps. Citrulline boosts arginine and nitric oxide, opening up blood vessels so you get more blood, oxygen, and nutrients to your muscles during lifts.
- 200mg Caffeine Anhydrous — a solid energy kick that most folks can use without issues. It ramps up alertness, energy, and workout motivation without jumping to that 300mg+ level that can mess with your vibe.
- 200mg AlphaSize® Alpha-GPC — a quality choline source for better focus and muscle connection. It helps turn raw energy into sharp concentration, especially if you care about feeling every rep.
- 2,000mg Beta-Alanine — here for endurance by building carnosine to buffer muscle burn. The science backs it strong, but this dose is under the usual 3.2-6.4g daily studied amount, so it's best with consistent use or extra beta-alanine.
- 100mcg Vitamin B12 as Methylcobalamin — the active form, not some cheap version. B12 keeps your energy systems and nerves running smooth, fitting right into a stim-based pre-workout.
- Fully disclosed label — everything's listed out clear as day. In a world of hidden blends, this lets you check if it stacks up to what you've read, no guesses.
- AstraGin® at 25mg — added to help your body absorb nutrients better by tweaking gut transporters. Data often points to 50mg for best results, so this is on the lighter side, but it shows they're thinking about making the formula work harder, not just adding more caffeine.
- ActiGin at 25mg — thrown in for better performance and workout efficiency. It's not the main event, but it fits the goal of boosting your output beyond just stims.
Who Is This For?
- Bodybuilders hunting pumps and better workouts without max stims. 6g citrulline malate delivers the flow for volume days on chest, shoulders, arms, and legs, with 200mg caffeine keeping you going strong.
- Mid-level lifters in hypertrophy programs with decent volume. It hits with vasodilation from citrulline, drive from caffeine, and some burn-fighting from beta-alanine for when sets get real.
- Gym folks who need a boost but hate how high-stims kill sleep or recovery. 200mg is that Goldilocks zone—sharpens mornings or evenings without the fallout.
- Lifters big on focus and feeling the muscle work. AlphaSize® alpha-GPC adds that brain boost for better concentration and contractions, beyond just heart-pumping energy.
- People who check labels and hate blends. Everything's out in the open, so you see the strong stuff like 6g citrulline and decide for yourself.
- Bucked Up loyalists who dig the brand's vibe but want something everyday-usable. Deer antler velvet keeps it signature, while the stim level and clear label make it friendly for more people.
How to Use
Grab one serving 20-30 minutes pre-workout so caffeine and focus kick in for your sets. If you're new to stims or sensitive, try half first—200mg can hit hard. Mix with 10-16 oz cold water in a shaker; more water mellows it, less amps it up. Empty stomach speeds it up, but a light meal an hour before helps if stims bug you. Don't stack with other caffeine sources unless you're tracking totals, as they add up fast. It goes great with creatine, electrolytes, and intra carbs for big sessions. No need to cycle the non-stims, but take caffeine breaks sometimes to stay sensitive. Keep it sealed, cool, and dry to avoid clumping.
What to Expect
Minutes 0-10: it's more about building up than a huge rush, especially on an empty stomach. Minutes 10-20: 200mg caffeine hits with better alertness, and you might get some beta-alanine tingles at 2g. Minutes 20-40: prime time to start—focus sharpens from caffeine and AlphaSize®, and citrulline pumps show as sets stack up. Minutes 40-90: energy holds steady thanks to the moderate dose, keeping things productive without the shakes from stronger stuff. Days 1-7: you feel the immediate pump, energy, and focus. Weeks 2-4: beta-alanine steps up as carnosine builds, but at 2g it's a slower climb than full 3.2g+ daily.
Frequently Asked Questions
How much caffeine is in Bucked Up pre-workout?
This formula provides 200mg caffeine anhydrous per serving. That puts it in the moderate-stim range—strong enough for clear workout energy and focus, but lower than the 300-400mg doses used in more aggressive high-stim pre-workouts.
Is 6g citrulline malate a good dose?
Yes. 6,000mg citrulline malate is one of the strongest parts of this formula and sits in the range serious users look for when they want meaningful pump and blood-flow support. It supports nitric oxide production through increased arginine availability, which is why the workout feels fuller and more vascular.
Is the beta-alanine dose fully clinical?
Not quite. Beta-alanine is included at 2,000mg, while the most studied range for increasing muscle carnosine and supporting high-intensity performance is typically 3,200-6,400mg daily. It can still contribute over time, but it is below the classic full clinical target.
What does AlphaSize® do in this formula?
AlphaSize® is a trademarked alpha-GPC ingredient used here at 200mg to support focus, attention, and neuromuscular performance. It helps the formula feel more locked in and coordinated, not just stimulated.
Will this make me tingle?
Possibly. The 2,000mg beta-alanine dose can cause the familiar tingling sensation called paresthesia in some users, especially on an emptier stomach. It is harmless and related to the ingredient, not a sign that something is wrong.
Should I take this every day or only on workout days?
Most users will use it on training days, but the beta-alanine component works best with consistent daily intake because carnosine builds gradually in muscle. If beta-alanine saturation is a priority for you, many users add standalone beta-alanine on non-training days.
Can I stack this with creatine?
Yes, and it is one of the smartest stacks. This formula does not include creatine, so adding 3-5g creatine monohydrate gives you a research-backed ATP support ingredient that complements citrulline’s blood-flow effects and beta-alanine’s acid-buffering role.
Is taurine meaningfully dosed here?
Not relative to the research range. Taurine is included at 100mg, while performance studies often use 1,000-3,000mg. It is present, but it is not a major driver of the formula’s real-world effects.
What is deer antler velvet doing in this product?
Deer antler velvet is a signature Bucked Up inclusion and part of the brand’s identity. At 50mg, it is best viewed as a specialty add-on rather than the primary engine of the formula, which is driven much more by citrulline, caffeine, and AlphaSize®.
Is this a good beginner pre-workout?
It can be, but beginners should start with half a serving. The 200mg caffeine is manageable for many people, but if you are new to stimulants, tolerance varies widely and a half serving is the best way to gauge response.
