8g Citrulline, 300mg Paraxanthine, No-Hidden-Stuff Power

Core Nutritionals Energon Pre-Workout is a solid, no-BS pre that's all about big pumps, fighting fatigue, and clean energy without dumping a ton of caffeine. No hidden blends here—everything's out in the open. You've got 8g L-citrulline for better blood flow and pumps, 3.2g beta-alanine to build up carnosine and push back against burnout, 2.5g betaine anhydrous for more power and stamina, plus a focus and energy mix with enfinity® paraxanthine, Cognizin® citicoline, N-acetyl L-carnitine, huperzine A, Senactiv®, and VasoDrive-AP®.

The star is 8,000mg L-citrulline—that's a real dose that stands out from the weak stuff. Citrulline boosts arginine levels better than taking arginine straight, which ramps up nitric oxide for wider blood vessels, better flow, and more nutrients to your muscles. Studies show it helps with blood flow and performance, and this amount is legit, not the skimpy 3-4g you see for show. In the gym, you'll notice bigger pumps, muscles feeling more fueled, and that locked-in vibe as you get going.

Beta-alanine hits 3,200mg, the dose backed by research. It loads your muscles with carnosine, which fights acid buildup during tough reps. That means less of that burning feeling that cuts sets short. It shines in workouts lasting 1-10 minutes, like hypertrophy sets, supersets, intense intervals, or long reps. Right away, you might feel the tingle. Over 2-4

Key Highlights

  • 8,000mg L-Citrulline — this is the real deal dose that you'll actually feel. It boosts arginine to crank nitric oxide, opening up blood flow for better oxygen, nutrients, and that full pump that sticks around during your lifts.
  • 3,200mg Beta-Alanine — the proven dose that builds muscle carnosine over time. More carnosine fights off acid buildup, so you push harder through repeat sets, intervals, and those 1-10 minute grinds without burning out fast.
  • 2,500mg Betaine Anhydrous — spot-on for the research, helping with power, stamina, and keeping cells hydrated. It's a sleeper hit in pre-workouts because it boosts your output without just cranking up stims.
  • 300mg enfinity® Paraxanthine — a fresh take on energy that beats basic caffeine blends. It's caffeine's main breakdown product, and folks say it feels smoother, more focused, with less crash.
  • 250mg Cognizin® Citicoline — a top-shelf nootropic dose backed by studies on attention and movement. It ramps up acetylcholine for laser focus, better task lock-in, and stronger mind-muscle feel during complex or high-rep work.
  • 1,000mg N-Acetyl L-Carnitine HCl — a hefty hit for brain energy and focus support. It teams up great with citicoline and huperzine A, making the mental side deeper than just a stim buzz.
  • 254mg VasoDrive-AP® — fancy peptides from casein that back up citrulline with extra blood vessel support. You don't see this in cheap pre's—it's a sign this one's built for real gains, not just looks.
  • 50mg Senactiv® — a patented plant extract that helps with cell energy and bouncing back. It adds staying power, making this more than your basic pump-and-stim mix.

Who Is This For?

  • Bodybuilders in volume-heavy phases who need a pre to keep reps strong after the early exercises, not just a quick hype. 8g L-citrulline and 254mg VasoDrive-AP® deliver big, lasting pumps, while 3.2g beta-alanine fights burnout in repeat sets.
  • Mid-to-advanced lifters on push/pull/legs or upper/lower who dig focus as much as energy. 300mg enfinity® paraxanthine, 250mg Cognizin® citicoline, 1g N-acetyl L-carnitine, and huperzine A sharpen execution, mind-muscle link, and cut mid-set distractions.
  • Strength folks in build-up phases needing bar speed and volume after mains. 2.5g betaine anhydrous boosts power and capacity, beta-alanine buffers fatigue in packed sessions.
  • High-stim fans who hate the jitters from caffeine bombs. Enfinity® paraxanthine gives strong energy that often feels smoother and more workout-ready than basic caffeine.
  • Morning crew needing quick wake-up and full-session lock-in. The stim and focus mix perks you fast, blood flow and endurance keep it from dropping after warm-ups.
  • Cutting athletes wanting to hold onto pump, intensity, and headspace on low cals. Citrulline, betaine, paraxanthine maintain drive, focus stack helps when diet drag hits.

How to Use

Mix 1 scoop in 10-16 oz cold water and sip 20-30 minutes pre-gym. That lines up the energy and focus while pumps build during early sets. If paraxanthine or high stims are new, try half first to check how it sits.

Use a shaker for even mix—multi-ingredient pre's blend better that way. Too strong flavor? Add water; it won't weaken the goods. Best on an empty stomach or after a light snack 60-90 minutes out, since heavy food slows the kick.

Don't stack with other pre's, burners, or big stims—300mg enfinity® paraxanthine is already potent. Creatine, intra carbs for long hauls, or post protein fit great. No need to cycle citrulline, betaine, or beta-alanine, but check if stims feel weaker over time and ease off. Keep it sealed cool and dry for best powder.

What to Expect

Minutes 0-10: right after mixing and drinking, the mental side hits first. It goes down easy, and beta-alanine tingles might show if you're prone.

Minutes 10-20: paraxanthine and nootropics bring alertness, that urge to train, and clearer headspace. You feel pumped to go, focused on the work, less distracted.

Minutes 20-40: prime time for most workouts. 8g citrulline shines as flow picks up, pumps build, and the brain stack sharpens your moves.

Minutes 40-90: where good pre's shine, and Energon delivers. Energy holds steady, focus doesn't crash like plain caffeine, and pump plus stamina keep paying off late.

Days 1-7: you'll figure out your vibe with paraxanthine and tingles fast. Pump, focus, energy hit day one; beta-alanine's endurance builds slower.

Weeks 2-4: that's when it really clicks. Muscle carnosine from daily 3.2g beta-alanine makes hard sets easier to handle, and the pre feels more reliable session after session.

Frequently Asked Questions

How much stimulant is in Energon Pre-Workout?

Energon contains 300mg enfinity® paraxanthine per scoop. The exact caffeine-equivalent feel varies by individual, but this is firmly a high-stim pre-workout and should be treated as such, especially if you also use coffee, energy drinks, or fat burners.

Is Energon fully transparent or does it use a proprietary blend?

It is fully transparent. Every key active is disclosed with an exact dose, including 8g L-citrulline, 3.2g beta-alanine, 2.5g betaine, 300mg enfinity® paraxanthine, 250mg Cognizin® citicoline, and 254mg VasoDrive-AP®.

Why does this formula use paraxanthine instead of regular caffeine?

Enfinity® paraxanthine is the primary metabolite your body produces from caffeine, and many users report a cleaner, more focused performance feel from it. In practical use, it is often chosen to provide strong alertness and drive with less of the rough jitter-crash pattern some people get from caffeine-heavy formulas.

Will Energon make me tingle?

Possibly, yes. The formula contains 3.2g beta-alanine, which is the classic clinical dose and commonly causes a harmless tingling sensation called paresthesia in some users, especially when taken on a relatively empty stomach.

How long before training should I take Energon?

Most users will do best taking it 20-30 minutes pre-workout. That allows the paraxanthine and nootropic layer to come online before training while the citrulline-supported pump effect becomes more apparent as exercise begins.

Do I need to take Energon every day for it to work?

The energy, focus, and pump effects are acute, so you’ll feel those on day one. But beta-alanine works through muscle carnosine loading, so consistent use across weeks is what unlocks its full endurance and fatigue-buffering value.

Is this a good pre-workout for pump-focused training?

Yes, very much so. The 8g L-citrulline dose is serious by category standards, and the addition of 254mg VasoDrive-AP® gives the blood-flow side of the formula more depth than many stimulant-forward pre-workouts.

What should I stack with Energon?

A standalone creatine monohydrate is the smartest addition for most users because this formula does not include creatine. Creatine supports rapid ATP regeneration, which pairs well with beta-alanine’s acid buffering and betaine’s work-capacity support.

Does Energon contain allergens?

Yes, it contains VasoDrive-AP®, which is derived from hydrolyzed milk casein. Anyone with a milk allergy should avoid it unless cleared by a medical professional.

Is Energon good for evening workouts?

Only if you have exceptional stimulant tolerance. With 300mg enfinity® paraxanthine, this product is more naturally suited to morning or afternoon training because it can interfere with sleep in stimulant-sensitive users.

Smaller than pictured but still a good choice for LG-XL dogs/power chewers!
Color: 3 PC-Beef-Red, Color: 3 PC-Beef-Red
Fantastic that these come in a 3 pack - I wish more chew toys did this! The base for these chew toys is pretty tough! The center & ends are hard enough to withstand both my bully mixes & my Irish wolfhound/Great Dane cross. They’re safe enough for even the largest power chewers! (With Supervision) my American Bully got the rubber spikes chewed off in under 20 minutes which is mildly disappointing but he’s a true powerhouse & master destroyer of all chews so I’m not that bent out of shape about it. I do wish they were as large as they appear in the ad pics but isn’t that the game we all play ordering offline anymore? 🤷🏻‍♀️ • Pro Tip: smear this toy in peanut butter (xylitol free!), wet food mixed into a slurry with water or bone broth + kibble/treats, yogurt, or even pumpkin puree and freeze for a few hours & relax while watching all the organic engagement your dog gets out of this toy!

My dog loves it
Color: 1 PC-Beef-Red, Color: 1 PC-Beef-Red
The bone arrived today and my dog loves it. He is a very aggressive chewer and destroyed almost all his toys so far, even toys that were advertised for aggressive chewers unfortunately didn't held out long, the longest so far was a stuffy we couldn't find anymore and that one lasted him a few weeks but everything else lasted him an hour up to a few days max, even bones don't last him long so we have our hopes set on this bone to satisfy his chewing needs. I will update my review later on sturdiness, since we just got it and I can't review that yet but so far he loves it he has been chewing on it non stop, he already managed to get very small pieces of as shown in picture but with a regular bone he would've already been much much further. The bone is only 10 bucks so the value for money you get based on my experience so far is amazing! But also for this I will come back later to touch upon more. The size is good, our boy is a medium sized dog and this bone was advertised for medium to large size dogs and I thinks the size is just right for our boy . And there is definitely a beef flavor on it you can smell it but it doesn't smell bad it's a nice smell and not very strong but when he is chewing on it you smell it. I would based on my experience so far definitely recommend this bone but also on this I will touch back upon later if it's worth it in the long run. So far a very happy dog and owners here. Edit on May 8th (original review was on March 11th) He still hasn't managed to destroy it it's the first (cgew)toy he hasn't managed to destroy yet which is very impressive since he managed to destroy the even most toughest things we got for him in a week tops and bones within 1, 2 days tops, so we are very happy and pleased with this bone and will definitely get more later. He still enjoys chewing on it and leaves our things mostly alone for some reason he just likes stealing my things and chew on it lol. So 2 months later still stand by recommending this when your dog loves to chew and destroys everything he puts his mouth on.

Extremely durable, dogs love them
Color: 2 PC-Beef-Red, Color: 2 PC-Beef-Red
I was looking for the toughest and most durable dog chew bone I could find and this is it. I have bought multiple other brands that claim to be very durable and tough for a very long time and this is the one for sure. The shower has described this phone accurately and it truly does last. I purchased this bone about 2 months ago. As you see from the photos attached, this is a very well made chew bone and my aggressive pitbulls can't tear it apart do they try. They never get tired of it and chewing it every single day for hours on and keeping them very occupied. I have two bones and three pitbulls that chew on it every day. It is so adorable and has an awesome flavor to it which I think entices them even more to want to chew on it. The durability and Lasting power is amazing to me with these tough chewers. I highly recommend this product to everyone out there. I will say only one negative and that is that the middle wraparound piece they were able to pull off but that is not a big deal because there is plenty of bone which was under that cover in the middle of the bone. There's a few mauled chips missing from the ends but the life of this bone is obviously going to be a long time which really surprised me. Give it a shot if you have heavy duty chewers and you will find how awesome this phone really is and it's durability and strength our second to none in my opinion.

My dog loves it.
Color: 1 PC-Beef-Red
My dog is a super aggressive chewer when it comes to toys. Anything that is soft he rips apart. This one has a wonderful squeaky sound that makes him happy and he enjoys the smell of it. This is a very strong material and definitely worth the price.

Alright, here's a product review for those Tough Dog Toys: Finally, a Toy That Survives My Monster! - Tough Dog Toys Review As the owner of a determined (and I mean determined) large breed chewer, finding toys that last longer than five minutes has been a constant and often frustrating quest. I've gone through countless plush toys ripped to shreds, rubber toys with chunks missing, and even some "indestructible" toys that met their demise far too quickly. That's why I was both hopeful and skeptical when I came across the Tough Dog Toys, designed specifically for aggressive chewers and large breeds. Let me tell you, these bone-shaped nylon toys are living up to their name. My power-chewing Labrador has been going at this thing for days now, and I'm genuinely impressed. Where other toys have succumbed to his relentless gnawing, the Tough Dog Toy has held its own. There are some minor teeth marks, as expected, but absolutely no significant damage, no pieces torn off, and no signs of imminent destruction. "Almost indestructible" might actually be an understatement! The design is simple but effective. The solid nylon construction feels incredibly durable, and the bone shape is easy for my dog to grip and maneuver. It's also a good size for a large breed – substantial enough that he can really get a good chew going without it disappearing in his mouth. What I appreciate most is the peace of mind this toy provides. I no longer have to constantly supervise playtime, fearing that he'll ingest pieces of a destroyed toy. This feels like a safe and long-lasting option for even the most enthusiastic chewers. Pros: * Truly durable – stands up to aggressive chewing from a large breed. * Solid nylon construction feels virtually indestructible. * Safe design with no small parts to break off. * Good size and shape for large dogs to grip and enjoy. * Provides long-lasting entertainment. Cons: * May show some teeth marks over time (though this hasn't compromised its integrity). * It's a fairly hard material, so dogs who prefer softer toys might not be as interested. Overall: If you're at your wit's end trying to find a toy that can withstand your aggressive chewing large breed dog, I highly recommend giving the Tough Dog Toys a try. This bone toy has proven to be the most durable option we've encountered, offering excellent value for money and, most importantly, a safe and engaging chewing experience for your furry friend. Five out of five paws!
