Christian Guzman is Back: Ghost Legend CG V4 – No Tingles, No Alpha-Yo!

Note: The 2023 Christian Guzman collab has arrived, and it has a new name. See it in our Ghost CG PRE article!

Ghost Legend Lemon

Now that the new Ghost Legend V2 is out and shredding sales records, it’s time for its Athlete Collab season to follow. And there’s no better way to do that than with Legendary Ghost athlete Christian Guzman, the shining star of social media fitness!

This time, Christian Guzman is getting his own series of supplements, which includes the Stim-Free Ghost Focus supplement as well as a Lemon Butter Cake Whey flavor. We get into those in the future (follow our Ghost News) — today we’re here to talk about this incredible new pre workout formula!

Ghost Legend CG V4 announced… and more

This is the fourth “Ghost Legend x CG” collaboration, and from our point of view, it’s the best one ever. It’s once again in a Lemon flavor, which will likely be great, but we’re talking about this formula.

Inside CG V4, we’ll see some incredible ingredients – and some notable absences too:

Ghost legend Christian Guzman V4

The fourth installment of the legendary Christian Guzman limited edition series of Ghost Legend is here, and it looks incredible – especially if you don’t want beta alanine or rauwolfia!

  • A double strike of nitric oxide from L-citrulline and Citrulline Nitrate
  • 300mg caffeine paired with theobromine and bitter orange extract
  • Full clinical dose of betaine for performance and muscle building (2.5g)
  • Senolytic support from Senactiv
  • Triple focus strike from high-dose L-Tyrosine, Taurine, and Alpha-GPC

No beta alanine or alpha yo?!

It’s the last point that’s going to be a topic of discussion for most users, since we’re expecting higher performance than the standard Legend in some aspects, but less intensity in others. Those who don’t like beta alanine tingles and/or the feel of alpha-yohimbine are going to be incredibly excited, however.

We get into the details below, referencing a great deal of science in our other Ghost-based articles and comparing to the previous Guzman collab. Before that, make sure you check out the product availability and sign up for PricePlow’s Ghost supplement news… the Legends are always up to something hot:

Ghost Legend CG V4 Ingredients

From the intro alone, you should know if you’re interested in this one. Legend CG V4 looks to be a “high-intensity but low annoyance” experience based upon what’s in it but also what’s not in it.

  • Full Yield Citrulline – 6000mg*

    Ghost Legend Christian Guzman V4 Ingredients

    Take a look at this profile! Is it the best Christian Guzman collab to date? We think so.

    This is our nitric oxide boosting blend, and it’s a proper solid one at that.

    But let’s break this one down in better detail first, since the “6000mg” here is confusing. What Ghost is saying is that you’re getting a 6g yield of actual citrulline, which is awesome. However, the two ingredients combined bring even more than that:

    • 4.66g Vegan Fermented L-Citrulline yielding 4.52g actual citrulline
    • 2g Citrulline Nitrate (NO3-T) yielding 1.48g actual citrulline

    Don’t let Ghost forget those nitrates!

    So not only do we have 6g citrulline, we also have about half a gram of nitrates too! If anything, this label is selling itself short — and we’re not going to allow that.

    We’ve written about these ingredients countless times, but the point is that they take two different pathways to generate more nitric oxide, generating more vasodilation and leading to improved blood flow, nutrient delivery, and training pumps and endurance. There’s likely even better recovery too. The doses are well above what is studied and we can anecdotally feel in the gym.

    If you want to explore these two in depth, read the citrulline section in our Ghost Legend article and the nitrates section in our Ghost Pump article. Note that Ghost Pump uses arginine nitrate, but most of the nitrate-based since still applies.

    Vitamin C included

    Also note that Ghost included Vitamin C in CG V4, something that’s not in the standard Legend pre workout. We also explain this in the Vitamin C section of the nitrate-based Ghost Pump article, but the long story short is that the popular antioxidant vitamin prevents nitrate tolerance. Good til the last drop.

  • Betaine Anhydrous – 2500mg

    Betaine is an incredible ingredient that acts as an osmolyte, assisting with water regulation and transfer amongst cells. Its importance cannot be understated, and it brings the following benefits:

    • Better athletic performance and endurance
    • Increased muscle growth
    • Significant fat loss (research published in females)
    • Improved cell hydration and water retention

    You can read the entire storyline behind betaine’s research (about 15 citations worth) in the betaine section of our article on Ghost Size, which is the brand’s upgraded muscle-building supplement that includes creatine, betaine, epicatechin, and more.

    Are you noticing a trend here? With CG V4, Ghost is pulling in science-backed ingredients from several of its other new V2 era supplements!

  • Senactiv (Panax notoginseng (root) and Rosa Roxburghii (fruit)) extracts – 50mg


    Out with the old, in with the new. Regenerate senescent cells and improve performance with NuLiv Science’s Senactiv

    It’s very well established that Senactiv is a favorite ingredient of Dan Lourenco, Ghost’s co-founder and CEO. Made by NuLiv Science, Senactiv is what’s known as a senolytic ingredient, which means it helps clear out old lesser-functioning cells to make room for new ones.

    The research on not just this ingredient, but this entire class of ingredients is fascinating, and anecdotally, we’ve found Senactiv to provide a unique endurance-enhancing effect that is tough to find in stimulant-free ingredients.

    The greatest benefits are that the ginseng present in Senactiv helps reduce exercise-induced inflammation, and can improve VO2 max. In addition, greater post-workout glycogen reload has been noted, which bodes well for anyone eating Ghost’s famed “physique destroyers” post workout.

    We dive incredibly deep into the science in our article titled Senactiv from NuLiv Science: Regenerate Senescent Cells and Perform Better.

  • L-Tyrosine (Vegan Fermented) – 2000mg

    Fronting the Ghost Smart Energy blend, we have double the dose of L-Tyrosine than we have in Legend V2! This is going to bring even more neurotransmitter production, including norepinephrine, epinephrine, and dopamine. In addition, tyrosine is important for thyroid hormone production, so it’s never a bad thing to have some around.

    It’s been a fun year for Ghost. Bubblicious is back, and this time they’re bringing Lightning Lemonade along with Strawberry Splash!

    2g is where the dosing starts to get “serious” here, and it’s likely you’ll be feeling it in terms of focus and vigilance. At this point, it may even help a lot if you’re sleep-deprived!

    You can read more about it in the L-Tyrosine section of our Ghost Legend article, but just remember… CG V4 has twice as much!

  • Taurine – 2g

    Pairing well with betaine is taurine, another osmotic hydration agent with a huge slew of benefits ranging from endurance to cognition. This is a “conditionally-essential” amino acid, meaning that our bodies can make it themselves, but we’re always better off with more.

    Once again, as with tyrosine, Christian Guzman has decided to double the standard Ghost Legend dosage! While 1g is a clinical dose, 2g may bring even greater cell enhancement and neuroinflammation protection.

    You can read more about taurine in the main Ghost Legend write-up. With 2g here and 2.5g betaine, we’re very confident that you’ll be primed for a solid “water-driven pump” on top of the citrulline+nitrate nitric oxide boost, so drink plenty of water with CG V4!

  • Alpha-GPC (Alpha-Glyceryl Phosphoryl Choline 50%) – 600mg

    Ghost Gamer SPK Blue Raspberry

    You like focus, do ya? Then Ghost Gamer could be worth trying when you need a touch less caffeine!

    Alpha-GPC serves as the primary focus ingredient, and is of course assisted by taurine, tyrosine, and the stimulants below. This is a high-bioavailability choline source, and it’s dosed to the point where we have seen strength improvements on top of its cognitive enhancement.

    The reason it boosts cognition is because choline is a precursor to acetylcholine, a compound we call “the learning neurotransmitter” that’s heavily involved in synaptic exchange.

    For a third time in a row, we have twice the dose of Ghost Legend, and you can read more about it in the Alpha-GPC section of our Ghost Legend discussion.

    The biggest difference is, with a 600mg dose, we have actually seen the strength improvements in trials… and from what we know so far, that hasn’t yet been shown at 300mg. Once again, Guzman is looking good here.

  • Caffeine Anhydrous – 300mg

    C-c-c-c-combo breaker! We’ve finally hit an ingredient where CG V4 is not twice the dose of Legend V2, and in this case, that’s a good thing.

    Whereas Legend has 250mg natural caffeine, Christian opted for a higher hit of caffeine, but stopped at a reasonable 300mg in two scoops. Another major difference is that CG V4 has caffeine anhydrous, which shies away from the natural caffeine source in the main Legend pre. Most of us will be fine with that, since this is the standard caffeine on the market.

    Ghost Legend CG V4

    This tub is a beautiful change-up for Ghost. The CG Series has become refined.

    While we cover the science behind caffeine in our Legend article, but you should know how it works for you at this point. If you don’t want 300mg, you can just take 1-1.5 scoops and still get a very solid workout with clinical doses of several key ingredients.

  • Theobromine – 100mg

    This is the one ingredient that Christian Guzman decided not to tinker with: Theobromine remains at 100mg, just like Legend V2. At this point we were expecting a bit more, because why the hell not, but perhaps they ran out of room in this monster tub, which does weigh in at 19g in a two scoop serving.

    With theobromine, you get longer lasting effects that are similar to caffeine, but aren’t as profound. It’s found in chocolate and has anti-inflammatory, cardioprotective properties, and has a unique effect in that it enhances “feel” in subjects.

    Once again, the science is all covered in depth in our main Legend write-up.

  • Bitter Orange (Citrus aurantium) Fruit extract – 60mg (yielding 30mg synephrine)

    Without rauwolfia providing alpha-yohimbine, what’s our “bonus” stimulant going to be to top off the caffeine and theobromine? The answer is bitter orange extract, which comes from citrus aurantium.

    Theobromine Effects

    Interesting: High-Dose Theobromine can dial up the “feels”. Exactly what we expect with a Guzman supplement!

    Thanks to some details beneath the active ingredients of the label, we know that there’s 30mg synephrine inside. This is a beta-2 and beta-3 adrenergic agonist that amplifies energy expenditure and fat burning.

    Once again borrowing from other Ghost supplements, we wrote about bitter orange in Ghost Burn, where 60mg yielded 30mg synephrine as well, so the brand is sticking to their 50% standardization. At this dose, we have not too much, but definitely not too little.

  • AstraGin (Panax notoginseng and Astragalus membranaceus) Root extracts – 50mg

    AstraGin Nutrient Transport Study Results

    AstraGin hits nutrient transportation from multiple angles!

    It simply wouldn’t be a Ghost supplement without this absorption amplifier included from NuLiv Science! AstraGin ginseng and astragalus extracts to improve both absorption from the gut as well as transport to cells. It has been shown to be effective with several types of ingredients, including the citrulline which we have here.

    AstraGin makes the rest of the tub better, and that’s impressive because this tub is already extremely well-crafted. It will be hard not to feel extraordinary with CG V4.

Long story short, this supplement looks absolutely fantastic, especially if you’re tired of beta alanine and/or alpha yohimbine everywhere. It will still boost endurance and bring intensity, but it may just dial down the “feels” a bit.

Compared to Ghost Legend V2, the saddest loss is that there’s no Nitrosigine in CG V4, but that will of course stay in the main Legend variety and we’re excited about betaine and citrus aurantium’s addition to this one.

Comparing to CG V1, V2, and V3

When Ghost began doing these athlete collabs, they kept the formulas very similar, with perhaps just a change in one ingredient, such as more caffeine in CG V1 and V2. The flavor systems were really the bigger story there. You can see those two formulas below:

The earlier collab labels: Christian Guzman Legend V1 vs V2

Ghost Legend Guzman Ingredients

V2 and V3 Shown Here! Essentially the same label in Guzman’s two lime-based flavors!

CG V3 changed how Ghost did collabs

Then, with CG V3, Ghost took a completely different turn, testing a wildly different formula. The flavor system was great, but the big news was the unique formula. Not only was it a fun change-up, the project was a great test bed to see what would make it into the official Ghost V2 era supplements.

A look at Guzman Legend V3

CG V3 was a massive success, but unfortunately, its glycerol inclusion didn’t work out too well. However, the tingle-reduced beta alanine was somewhat of a success, and Ghost ended up porting that innovation into Ghost Size. With that done, CG V4 was free to remove all beta alanine – and now we’re left with a zero tingle supplement that still provides endurance benefits, and can still be stacked with Size if you want.

    2021 has a lot of “V2s” set for many of Ghost’s supplements – sign up for alerts on our Ghost news page so you don’t miss a single one!

    Ultimately, this supplement’s success will hinge on two things:

    1. If users are happy without beta alanine
    2. If users would rather have citrus aurantium / synephrine instead of alpha-yohimbine

    The formula is a knockout. We’ll miss the Nitrosigine, but sometimes folks want a break from tingles and alpha-yo’s intensity. It brings together several highlights from other Ghost V2 series supplements, and is what we consider Christian Guzman’s finest.
