6g Citrulline, 200mg Caffeine, Fully Disclosed Performance Support

Bucked Up PeakO2 Adaptogenic Performance Powder is basically a solid mid-stim pre-workout with the classics: stuff for nitric oxide to help with pumps and blood flow, beta-alanine to fight fatigue, caffeine for quick energy and alertness, plus a bit of nootropics and electrolytes to make training feel better. It's not fancy, and that's why it works. It sticks to ingredients that actually help in the gym instead of flashy extras.

The star is 6,000mg of citrulline malate 2:1. That's a real dose for pre-workouts. Citrulline turns into arginine in your kidneys better than taking arginine straight, boosting nitric oxide and widening blood vessels. In the gym, that means fuller pumps, better blood to your muscles, and handling high-volume sets easier. At 6g, it's doing the heavy lifting for why this is called a performance powder.

Beta-alanine is at 2,000mg. Studies back it for intense efforts from 1-10 minutes, with daily doses usually 3.2-6.4g. It builds up carnosine in muscles over time, which buffers the acid that causes burning fatigue. Honest take: 2g is good, but under the full daily target. Use it every day to load carnosine; if only on workout days, you won't get the max benefits.

Caffeine anhydrous at 200mg makes it feel like a true pre-workout. It's enough to amp up alertness, cut how hard the workout feels, and boost your drive without going too wild. For many users, 200mg is the

Key Highlights

• 6,000mg Citrulline Malate 2:1 — this is the real deal dose where citrulline shines in training. It boosts arginine levels better than arginine itself, kicking up nitric oxide for wider blood vessels and that full pump feel serious gym folks chase.
• 200mg Caffeine Anhydrous — a solid dose that ramps up alertness, drive, and makes effort feel easier without hitting extreme stim levels. For a lot of people, this lifts your workout without the overkill of 300mg+ options.
• 2,000mg Beta-Alanine — a decent add for endurance, especially if you take it regularly. It builds muscle carnosine over time, buffering acid during tough sets so you delay the burn in reps, circuits, and conditioning.
• 200mg AlphaSize Alpha GPC — throws in choline for better focus and muscle connection that caffeine misses. Makes the whole thing feel like a workout booster, not just a buzz.
• Fully disclosed label — everything's listed with doses, so you can check it against what works. That's huge in a world of prop blends hiding weak ingredients behind cool names.
• Moderate-stim setup — made for everyday use, not one crazy session. 200mg caffeine is enough to perform but chill enough for folks who don't want stims messing with sleep.
• Citrulline plus caffeine combo — better blood flow from citrulline teams up with caffeine's mental kick. You get sessions that feel more responsive physically and sharper mentally.
• Beta-alanine plus caffeine combo — beta-alanine fights muscle fatigue long-term while caffeine boosts your push right now. Together, they handle what your body feels and how hard your brain wants to go.

Who Is This For?

• Intermediate lifters on hypertrophy blocks wanting reliable pumps and stamina between sets. 6g citrulline malate helps flow and feel, daily beta-alanine cuts burn in longer reps.
• After-work trainers needing energy without 300-400mg stim bombs. 200mg caffeine sharpens focus and output but keeps it manageable for recovery and sleep.
• Functional fitness folks with circuits, sleds, rows, high-output repeats. Beta-alanine fits 1-10 minute efforts, caffeine lowers how tough sessions feel.
• Bodybuilders after mind-muscle link and visible pumps over max stims. Citrulline malate and Alpha GPC make it more about performance feel than just buzz.
• Label readers who hate prop blends. This shows every active so you can check against what works, no trusting hidden stuff.
• Stack builders using a moderate pre base. No overload, easy to add creatine, intra carbs, or electrolytes for your style.

How to Use

Mix 1 scoop in 10-16 oz cold water, drink 20-30 minutes pre-training. Caffeine hits fast, citrulline lines up for warm-ups and working sets. If new to pre-workouts or low caffeine tolerance, try half scoop first for the 200mg and any tingles. Shaker beats stirring for mixing, add water for taste or hot sessions. Empty stomach speeds it up, light meal smooths if sensitive. Don't mix with other caffeine unless tracking total. Stacks well with creatine, intra carbs, full electrolytes for big volume. Store sealed, cool, dry for easy scooping. No need to cycle hard, but caffeine breaks help if tolerance creeps in.

What to Expect

First 0-10 minutes: not much, maybe early caffeine if on empty stomach. 10-20 minutes: energy and readiness build, possible mild beta-alanine tingles. 20-40 minutes: prime time, with 200mg caffeine going strong and 6g citrulline bringing better pump and feel. 40-90 minutes: keeps supporting without crashing like weak stuff, though pump depends on your style, water, and carbs. Days 1-7: mostly caffeine, focus, and flow right away. Weeks 2-4: beta-alanine steps up as carnosine builds, making tough sets and intervals easier to handle.

Frequently Asked Questions

How much caffeine is in Bucked Up PeakO2 Adaptogenic Performance Powder?

Each full scoop contains 200mg of caffeine anhydrous. That is enough for a noticeable increase in alertness, workout drive, and reduced perceived exertion, but it sits well below the ultra-high-stim pre-workout tier.

Is the citrulline dose in this formula actually strong enough to matter?

Yes. This product provides 6,000mg of citrulline malate 2:1, which is in the clinically meaningful range for supporting nitric oxide production, blood flow, and the fuller pump most users want from a pre-workout.

Is 2g of beta-alanine enough?

It is a useful dose, but it is below the 3.2-6.4g daily range commonly used in the literature. If you use the product consistently, it contributes to carnosine loading over time, but users seeking a full research-style daily intake may want additional beta-alanine from another source.

Will this make me tingle?

Possibly. Beta-alanine can cause a harmless tingling sensation called paresthesia, especially when taken on a more empty stomach or by users who are sensitive to it. At 2,000mg, some people will notice it and others will not.

Is this better for pump or energy?

It does both, but the strongest formula statement is the 6g citrulline malate for pump and blood flow. The 200mg caffeine gives solid energy, but this is not designed as an extreme high-stim product.

What does Alpha GPC do in this formula?

AlphaSize Alpha GPC at 200mg acts as a choline donor to support acetylcholine production, which is involved in focus and neuromuscular signaling. In practice, it helps the energy feel more directed and training-focused rather than just stimulant-heavy.

Can I stack this with creatine?

Yes, and it is a smart pairing. Creatine supports phosphocreatine regeneration for strength and repeated power output, which complements this formula’s citrulline-driven blood flow and beta-alanine-driven fatigue management.

Should I take this every day or only before workouts?

For the acute effects of caffeine and citrulline, use it before training. For beta-alanine to build muscle carnosine effectively, consistency matters, so daily use is more beneficial than only taking it occasionally.

Is this a fully transparent label?

Yes. The active ingredients are disclosed individually with listed amounts rather than hidden inside a proprietary blend. That makes it much easier to judge what is clinically strong and what is included at support-level dosing.

Is this suitable for evening training?

That depends on your caffeine tolerance and bedtime. At 200mg caffeine, many users will want to avoid taking it too close to sleep, especially if they are also using coffee or other stimulants during the day.
