6g Citrulline. 3.2g Beta-Alanine. Your go-to for real workout boosts.

Core Nutritionals Essential Pre-Workout lives up to its name—it's all about the key ingredients that show up in sports nutrition studies, with clear doses and no hidden blends. This isn't a throw-everything-in pre-workout chasing the latest trend. It's a balanced, moderate-stim option that makes your workout feel better: stronger pumps, more sets without fading, sharper focus, and steady performance instead of a big energy spike and crash.

The star is 6,000mg of L-citrulline, right in the sweet spot from research for boosting nitric oxide and workout performance. Citrulline turns into arginine better than taking arginine directly—it skips some breakdown in the gut and gets converted in the kidneys. That ramps up nitric oxide, which widens blood vessels for better flow. You notice fuller muscles, more oxygen to your working areas, and often better reps, especially in tough, high-volume sessions.

Beta-alanine comes in at 3,200mg, the standard daily dose to build up carnosine in your muscles over time. Carnosine helps buffer the acid that builds during intense efforts, so it really helps in those last burning reps where the fatigue usually wins. This isn't a quick-hit ingredient—you load it up over time, and 3.2g is what studies keep pointing to.

Betaine anhydrous at 2,500mg is another solid pick backed by evidence. Betaine acts as an osmolyte, which means it helps cells hold onto water, and it's a methyl donor for important body processes. In folks who train, this dose links to better power, more total work, and

Core Essential Pre by Core Nutritionals contains 50mg Magnesium, a effective dose for training performance and pump.

Key Highlights

  • 6,000mg L-Citrulline — a full dose that's spot-on from the studies for bumping up arginine and nitric oxide. You get better blood vessel widening, killer pumps, and solid flow to muscles, way better than those skimpy 3g versions.
  • 3,200mg Beta-Alanine — the everyday dose that builds carnosine in your muscles. As that ramps up, your muscles handle acid better during tough sets, helping you grind through those final reps.
  • 2,500mg Betaine Anhydrous — the dose you see in performance studies. It keeps your cells hydrated and supports metabolism, leading to stronger power and more capacity in trained guys.
  • 1,000mg N-Acetyl L-Carnitine HCl — a real amount for brain and performance perks, not just a tiny bit. It helps with energy in your cells and gives a clear-headed vibe for training, better than just more caffeine.
  • 300mg Alpha-GPC 50% — here for focus and muscle-brain connection. Since it's 50% pure, you get about 150mg of the active stuff—useful without going overboard, and that's straight-up honest.
  • 200mg Caffeine Anhydrous — enough to get you fired up without crossing into heavy-stim land. Makes this pre easy to use every day, unlike those 350mg+ monsters.
  • 50mg AstraGin® — the full dose from NuLiv Science, not a weak version. It boosts how your gut absorbs nutrients, which fits perfect in formulas loaded with aminos and performance boosters.
  • Electrolytes from magnesium, sodium, and potassium citrates — a smart touch for staying hydrated and keeping muscles firing. Not huge amounts, but they help with contractions, fluids, and pushing through sessions.

Who Is This For?

  • Intermediate bodybuilders on hypertrophy plans who dig pumps, tight sessions, and mind-muscle link over wild stims. 6g citrulline and 2.5g betaine boost flow, hydration, and rep quality for volume work.
  • Folks training 4-6 days a week needing a usable pre without stim burnout. 200mg caffeine drives you without the overload of 350-450mg stuff.
  • After-work trainers wanting support without sleep risks. Moderate caffeine fits later days, while citrulline, betaine, and beta-alanine handle the real work.
  • Strength-hypertrophy guys in build phases needing late-session help. 3.2g beta-alanine loads carnosine, key when acid limits sets.
  • Athletes who like clear labels to match against studies. Core's all about transparency, so you see every dose plain.
  • Gym rats wanting focus without exotic stim overload. ALCAR, Alpha-GPC, and 200mg caffeine give clean intent, not frenzy.

How to Use

Mix 1 scoop in 10-14 ounces of cold water and drink 20-30 minutes pre-training. Matches caffeine's timing to hit before big sets. Shaker's best for mixing. More water tones down flavor and spreads out beta-alanine feel.

Fine on empty stomach for quicker start, but if your gut's touchy, have a light meal and add time. Don't stack with other caffeine unless you're tracking it. Add creatine for energy stores, electrolytes for sweaty days, or intra carbs for long sessions. No need to cycle non-stims, but caffeine breaks can help sensitivity. Keep it sealed, cool, and dry.

What to Expect

Minutes 0-10: not much yet, just settling in, especially with water. Beta-alanine sensitive? You might feel a light tingle starting.

Minutes 10-20: caffeine kicks in, you feel alert and ready. Tingles can pick up, and warm-ups might show early vascular feels.

Minutes 20-40: prime time. Energy's steady, focus is on point, and citrulline pumps shine once you're lifting.

Minutes 40-90: still going strong without a sharp drop. Pump, hydration, and focus hold up in later sets as caffeine eases.

Days 1-7: quick wins from caffeine, citrulline, and focus, while beta-alanine starts loading. Weeks 2-4: carnosine builds, and it feels like a reliable upgrade for tough workouts.

Frequently Asked Questions

How much caffeine is in Core Nutritionals Essential Pre-Workout?

Each 1-scoop serving provides 200mg of caffeine anhydrous. That places it firmly in the moderate-stim category—strong enough for noticeable energy and training drive, but substantially more manageable for daily use than 300-400mg pre-workouts.

Is the 6g L-citrulline dose actually clinically effective?

Yes. Core provides 6,000mg of pure L-citrulline, which sits directly in the 6-8g range most often used in research for nitric oxide support, blood flow, and exercise performance. This is one of the strongest parts of the formula.

Why does this product make my skin tingle?

That sensation comes from the 3,200mg beta-alanine dose. It is called paresthesia and is a common, harmless effect of beta-alanine supplementation, especially when taken at fully effective doses. Some people feel it strongly, others barely notice it.

Is the Alpha-GPC dose high enough for focus?

The product includes 300mg of Alpha-GPC 50%, which yields about 150mg actual Alpha-GPC. That can contribute to focus, especially alongside caffeine and 1g N-acetyl L-carnitine, but it is below the 300-600mg active range often highlighted for stronger nootropic or power-oriented effects.

Do I need to use this every day or only before workouts?

You will feel the caffeine, citrulline, and focus effects acutely on workout days, but beta-alanine works best through daily saturation. If maximizing endurance benefits matters to you, consistent daily intake is ideal even on off days.

Can I stack this with creatine?

Yes, and it is a very logical stack. This pre-workout covers pump, buffering, energy, and focus, while a separate 3-5g creatine monohydrate product adds phosphocreatine support for strength and repeated high-intensity output.

Is this better for pump or energy?

It is balanced, but the formula’s strongest standout is probably the combination of clinically dosed citrulline, full-dose beta-alanine, and research-backed betaine rather than stimulant intensity alone. In practice, most users will notice both better pump and cleaner energy.

Should I take it fasted or with food?

Either works, but taking it 20-30 minutes pre-workout on a relatively empty stomach usually gives the fastest onset. A heavy meal can slow absorption and blunt how quickly the caffeine and focus ingredients come on.

Is this a good beginner pre-workout?

For beginners who want a serious but not extreme formula, yes. The key is starting with a half scoop first, because 200mg caffeine plus full-dose beta-alanine can still feel strong if you are new to pre-workouts.

What makes this different from mass-market pre-workouts?

The biggest differences are full label transparency and meaningful doses on the core ergogenics. Many mainstream formulas underdose citrulline, hide ingredient amounts in blends, or rely on heavy caffeine to create the illusion of effectiveness. Core’s formula is much easier to validate against actual research.

An Amazing Purchase, and Addition to the Bookshelf
Format: Hardcover, Format: Hardcover
Absolutely amazing, all three books are hefty and a pretty good size (Bonus if you have the Tales of Tamriel books, these are the exact same size and fit together nicelyon the shelf) and feel like a premium product, well worth the money. Three books covering The Histories, The Arcane, and Man, Mer, & Beast, are lavishly covered with the crest of Akatosh, and each book has a slightly diffrent colored hue to them, to assist in deferentiation. The slipcase is pretty stiff, although one corner was slightly dented, I'd contribute this to being a shipping or processing damage, outside of that no issues or defects, and it even has a magnetic clasp. The Histories. Starting off with book one, we establish the stories and books that cover the history and events leading up to Skyrim, the contents lists the various books in sub categories for easier navigation and grouping, beginning with History, Skyrim, Morrowind (three books cover a small portion of this), and Dragons, although some discuss things like Cyrodiil, the Third Era, etc, these all being derived from the in game source books are mostly relevant and scoped for Skyrim, and not the wider Elder Scrolls universe, for that I recommend the Elder Scrolls Online books, The Land and The Lore. Paired with the stories and texts are outstanding art renditions of characters, cities, weapons, and even concept art for Whiterun, armor, and so much more. Having a complete collection of books pertaining to world events and other major conflicts and political markers is a welcomed addition to this collection. With 229 pages, there's alot packaged in this book that will keep ypu interested and reading. Man, Mer, and Beast. Book two hosts 227 pages dedicated to various races, major figureheads like Ulfric Stormcloak, the Fauna of Skyrim, and even on things like The Blades and House Redoran. An assorted collection of books from Skyrim, once more paired with stunning artwork on nearly every page, it's a nice smorgasboard of topics, with the contents listing the sub sections as Races, Creatures and Beasts, Warfare, and Factions, I find it a great source for learning more about the Nords, Reachfolk, Dwemer, a surprising amount on Dunmer, and so much more. There's even a giant art piece of a Chaorus with a Falmer riding it! (Super cool right?) The Arcane. Book three will excite those studying the works of Shalidore, or anyone learning one of the many schools of magic. 218 pages cover the wide topic of magic and mysteria, with books discussing Deadra, The House of Troubles (Micheal Kirkbride fans will get a kick out of these), The Monomyth, the Divines, St. Alessia, and so so so much more. Elder Scrolls Lorebeards will appreciate this book the most, as it deals with all things, well, Arcane. I mean the stiff they decided to put in here is simply amazing, and blows my mind more with the artwork they include, again also featuring concept art for the game. Even better, there are a fair amount of books on the Deadric Prince of Madness himself, S H E O G O R A T H! This is probably, in my personal opinion, the best out if the three books. I'd say that for the sale price it's at for the time being, this is a must for any Elder Scrolls or Skyrim fan, and pairs nicely with the TES books mentioned at the start.

Stunning set will be loved by any Elder Scrolls fans
Format: Hardcover
It's hard to overstate how fantastic the production values on this set are. Bringing together the three previously published "Skyrim Library" volumes into a single box set, this is more than a collection of printed Elder Scrolls lore: it's a genuine collector's piece. As noted, this set is made up of three hardcover volumes, each of them previously published as individual books. They are collected here in a beautifully designed box. The box is a clamshell design that completely encloses the books so you can't see their spines while on the shelf. The carving on Alduin's wall from the game Skyrim is depicted on the outside, along with display text for your bookshelf, and the interior has an illustration of Alduin himself. Inside are the three hardcover books, and WOW are they gorgeous. Each is roughly 230 pages or so, give or take. The covers are a textured faux leather emblazoned with the Skyrim symbol. They feel hefty and weighty and are VERY well made. Truly impressive stuff. Also impressive are the interiors. Each book is jam-packed with in-game texts, lore, and more from the Elder Scrolls series (though branded as "The Skyrim Library," much of the material here can be found in games like Oblivion and Morrowind, too). The pages are a thick, study paper stock and almost every page is lavishly illustrated. As for the contents, they are terrific for any lover of the Elder Scrolls, Tamriel, and fantasy lore. Newbies will find this interesting and easy to get into, and old vets will delight in having this stuff in a nicely printed form. Vol. 1 is The Histories. The four sections within -- History, Skyrim, Morrowind, and Dragons -- offer a pretty comprehensive reading of Tamriel history from the perspective of mankind, from the early days of man to current, along with loads of Skyrim-specific lore, a quick overview of Morrowind (too quick; I hope they one day publish something similar on that setting), and stuff on dragons. Vol. 2 is Man, Mer, & Beast, covering the people and creatures of the world. In four sections -- Races, Creatures and Beasts, Warfare, and Factions -- you get extensive texts on the dwemer/dwarves, good material on other elves, texts on various factions operating in Skyrim, and more. Finally, Vol. 3 is The Arcane, dealing in magic and the gods. The four sections here -- Magicka, Religion, 2910: The Last Year of the First Era, and Aedra and Daedra -- delve more into the arcane and obscure, getting into the metaphysical aspects of Tamriel lore, accounts of the world's early days, material on the minor gods, and more. The material here is extensive, encompassing over 400 and maybe approaching 500 in-game books and texts. There is a LOT to sift through and read. If you've read some of the series' many in-game books, you know what to expect. If not, you'll be getting dozens of well-written tales, essays and pieces about Tamriel (NOT just Skyrim) and the overall world of Nirn, presented as if they were written by people who live in the game world. They vary in quality and tone, from serious to whimsical. That's a good thing, too. If one of the pieces doesn't catch your interest, just skip it. Each story is brief, usually only a page or two, making this a book you can just pick up and read for a few moments at a time without having to invest yourself. Things are arranged so if you want to read the books straight through you'll get clear thematic narratives, but it's not necessary to read them that way. You can skip around to the things that interest you. All in all, this set is GORGEOUS and is PACKED with stuff that will delight fans of the Elder Scrolls series, even those who prefer Morrowind, Daggerfall, or Oblivion to Skyrim. (No one actually prefers Arena to Skyrim, right?) The retail price seems a bit steep at $100, but the production quality makes it a decent purchase. Amazon's price is far batter than that, making this a no-brainer for lovers of Tamtriel lore. About my only complaint is the box's clamshell design, which makes accessing the books inside a bit of a pain and which does not match the equally gorgeous . They SHOULD look like a matching set when on the shelf -- the five individual books of the these two sets certainly do when removed from their respective boxes -- but the box designs are too different for that. My best guess is that maybe the clamshell design was used because it's sturdier and these are heavy books? Just a guess. But that's a nitpick from someone who likes his shelves to have a nice, matching look. Overall, great stuff. Huge thumbs up for fans of the series. Whether you are new to Elder Scrolls lore or are an old fan of it, either way you'll find a lot to like here.

Beautiful gift!
Format: Hardcover
Bought this for my father as a birthday gift. He absolutely loved it. It is beautifully illustrated, and if you just want a quick read, you can grab one of the books and open it to a page for one of the books inside the game itself.

Yet another great set!
Format: Hardcover
Due to hurricane irma in my area, this set was delayed to me. I was also out of power for a while, but now I have power and I also got my package today! I did pre-order this set along with the elder scrolls online book set. The set itself is huge. Has that good old classic skyrim artwork in the front there and inside it has the dragon. It's held together by a magnetic clip, which I do always enjoy. Now let's get to the good stuff, the books themselves. These are basically re-published versions of the original skyrim library if you haven't already bought those separately. Right off the bat I will recommend this set to collectors, and anyone who loves elder scrolls lore. Book 1 Or should I say Volume 1 Is about the histories, which are the history of the land itself, a brief history about morrowind, and of course dragons. I for one was trying to collect an in game collection of books, but there is so many of them that it's simply easier to read this for the entire thing. All in all, the histories are pretty intriguing because most of the history explained in the game is usually through someone else's perspective. Overall a great read. Volume 2 is about Man, Mer and Beast. Which basically goes into every single detail about all the races in skyrim, along with their traditions and the way they live kind of thing. The beast section is just that, detailed information about the beasts of skyrim, their legends and how they are in the wild. The last 2 sections are about warfare and fractions. Fractions history that you may or may not know like the companions or whatever fraction you joined in game. And warfare which is about the art of warfare and it's stories. Volume 3 the last volume is about the arcane, basically magic in skyrim it's history, it's religion, and it's stories. Yep there is a lot of history behind magic in skyrim if they made a whole book about it. The last section is interesting that it talks about Aedra and Daedra, Which is like Angels and Devils in skyrim simple terms. I mean most of the daedra are unpredictable despite their evil nature in the game. Like that daedra prince who just wants drinking party's and such, or that other daedra who just enjoyes tricking people. Overall though they are supposed to be evil. If you summon one of those guys in town I think you get an instant bounty. Anyways, the history about it is very intriguing. The books themselves by the way are just fantastic. AAA quality right here, Nice to the touch as well as its engravings. As like for the elder scrolls online set, you do not have to worry about bending the pages because of the books design. Every page as always has some kind of illustration next to it, giving every page in all these books some life to it. Although this one is a lot more text heavy than the elder scrolls online lore books. This set is fantastic! I wish Bethesda created sets about the older lore like morrowind or oblivion, but that's just my opinion. If they ever did more books
