Bucked Up Pre-Workout Review: Falls Short On Key Ingredients

Some links in this article are affiliate links, which means we earn from qualifying purchases. Learn more.

Bucked Up falls short of hitting clinical dosing standards for most of its performance-enhancing ingredients, so my expectations were set really low for this pre-workout.

However, after testing Bucked Up for 3-weeks, I was pleasantly surprised by how good I felt overall, which provided calm energy and good mental focus.

  • Bucked Up Pre-Workout costs around $1.66 per serving.  For context, when I analyzed over 50 pre-workouts, I found the average market value to be $1.61 per serving. 
  • Bucked Up fails to provide evidence-backed doses for the majority of the ingredients used. Only citrulline (6g) is provided in a full clinical dose. Despite this, I would still buy Bucked Up again (more on this below)
  • Bucked Up is a suitable option for beginners looking for a reasonably priced pre-workout that provides a calm mental focus and decent energy (without the jitters). It’s also a good option for anyone who doesn’t like high doses of beta-alanine, which can cause skin tingling.

Overall Rating: 3.6/5


  • Bucked Up provides a variety of ingredients to support pump, endurance, hypertrophy, and mental focus to suit a wide variety of workouts and training methods. 


  • Bucked Up uses a very simple blend of caffeine and alpha-GPC to deliver energy and mental focus
  • Tastes good
  • With 22 different flavors

Best For

  • People who don’t like strong beta-alanine tingles
  • Individuals who are budget conscious
  • Anyone who is sensitive to food dyes or wants to avoid them in their products for personal reasons
  • Someone looking for a well-rounded product that is not excessively high in stimulants
  • Keto dieters and intermittent fasters

Note: Some advanced users may only be interested in a pre-workout that has clinically effective doses for its performance-enhancing ingredients.  If that’s you, then check out my other review on Transparent Labs Bulk.  It’s the same cost as Bucked Up but meets clinical dosing standards for all 9 ingredients.  

What Is Bucked Up?

Bucked Up

Bucked Up is self-described as “the pre-workout everyone can agree on”. 

I quite like this description, since the formula is designed to be a well-rounded one without extreme doses that might otherwise disqualify some consumers. 

For instance, many pre-workouts now offer over 300mg of total stimulants, which may turn off some users who are not looking for extremely high-stim products.

With 200mg of caffeine, about the same amount as a medium (14oz) coffee, Bucked Up provides good energy without being excessive.

One thing that really differentiates Bucked Up from other pre-workouts on the market is their use of the unique ingredient, Deer Antler Velvet. Claims around deer antler velvet include improving strength, athletic performance, and muscle repair.

However, there is a lot more research needed on this ingredient to support its claims (more on that below). 

Bucked Up provides a variety of ingredients to support pump, endurance, hypertrophy, and mental focus to suit a wide variety of workouts and training methods. 

While Bucked Up uses a number of patented ingredients that have been shown effective in clinical trials for increasing strength and endurance, the doses found in Bucked Up fall below the doses used in the studies. 

Bucked Up does use artificial flavors in their products, but they avoid using artificial colors instead opting for natural options like beta carotene, beetroot powder, grapefruit powder, and blue spirulina.

Bucked Up is available in 22 different flavors (which is A LOT!). I was really grateful to see that Bucked Up provided descriptions of their unique flavors alongside the colorful names. 

For instance, Gym n Juice is described as a citrus blend, Swole Whip is pineapple-mango-vanilla, and Breezy Blast is Pineapple-Cranberry-Rum Cocktail. I personally tried the Aussi Fruit (Peach/Mango) flavor. 

For keto dieters and intermittent fasters, Bucked Up is one of the first companies I have seen to explicitly state that this pre-workout product will NOT break a fast or kick you out of ketosis.

Claims vs Reality:  How I Felt After Taking Bucked Up?

When I saw this product I didn’t have high expectations for it. 

The formula seemed like a well-rounded one but underdosed in the majority of performance-enhancing ingredients. 

Despite that, what really stuck out to me was how good I felt on this pre-workout. 

I felt happy and energetic, but also calm and dialed in. When I got to my workout, I was really able to dig into my last repetitions and tried increasing the weight on my final sets. 

This really reminded me of the mood-boosting/euphoric effect I felt with Wrecked Pre-Workout, but without any of the gastrointestinal side effects. 

I did appreciate that Bucked Up only had 200mg of caffeine per scoop. 

This is purely personal, but I enjoy drinking a coffee when I get to work and/or having an energy drink in the early afternoon. 

As such, the lower amount of caffeine in Bucked Up meant that I could reasonably add at least one other caffeine source to my day while staying under the FDA’s recommended safe limit of 400mg. 

The 6g of citrulline per scoop did provide a reasonable pump and I felt like I had good overall stamina to push through my workouts. 

The dose of beta-alanine in Bucked Up (2g) technically falls below the dose required in order to saturate the body’s levels, but since I have been taking beta-alanine almost daily for several months, this was enough for a maintenance dose for me (more on that below). 

I am not necessarily a fan of the beta-alanine tingles, though I have learned to appreciate them. With only 2g per scoop, Bucked Up caused only mild tingling and the effects subsided really quickly. 

I recommend this product for individuals who want the benefits of beta-alanine but don’t like the feeling of intense tingling.

Overall, I really enjoyed Bucked Up pre-workout and I look forward to trying new flavors in the future.

Bucked Up is a suitable option for beginners looking for a reasonably priced pre-workout that provides a calm mental focus and decent energy (without the jitters).

Citrulline Malate

Citrulline is an amino acid that helps dilate the body’s blood vessels and can improve blood flow to the muscles and support heart health. 

When taken pre-workout, citrulline may help delay fatigue, increase muscular strength and endurance, and improve recovery. So far, the research on citrulline is inconsistent at best but it does show potential as an ergogenic aid. 

Current literature indicates that a dose of 6-8g of citrulline pre-workout is ideal. 

Bucked Up offers 6g of citrulline malate per serving, meeting clinical dosing standards. 


Beta-alanine is an amino acid that plays a key role in creating carnosine in the body. Supplementing with beta-alanine can increase muscle carnosine levels by 15-85%. 

Carnosine acts as a buffer in the body, buffering the hydrogen ions that build up in muscle tissue and cause the sensation of fatigue. 

By supplementing with beta-alanine to increase muscle carnosine levels, you can increase endurance by delaying muscle fatigue to help you get the most out of every workout. 

Beta-alanine needs to undergo a loading phase and should be taken daily at a dose of 3-6g for 4-10 weeks. Afterwards, a maintenance dose of 1.2g daily is sufficient. 

Bucked Up contains 2g of beta-alanine, which is enough for a maintenance dose but falls shy of an effective loading phase dose. 

Beta-alanine comes with a side effect called paresthesia or skin tingling. It is a harmless side effect that many people love, but some users may find it uncomfortable or distracting. 


Caffeine is a stimulant that speeds up the central nervous system. This results in increased alertness and mood and can delay exhaustion. 

When taken pre-workout, caffeine can increase almost every aspect of exercise including HIIT and cardio performance, strength, stamina, and power. 

Caffeine levels peak within 30-60 minutes of ingestion, so you want to aim to take in your caffeine approximately 30 minutes before your workout. 

Bucked Up contains 200mg of caffeine. 

AlphaSize ® 

AlphaSize ® is a patented form of Alpha-GPC. 

Alpha-GPC is a form of choline and is a precursor to a chemical messenger called acetylcholine. Acetylcholine is essential for muscle control, involuntary movements like breathing, and various brain functions

Since acetylcholine can affect muscle and brain function, it’s theorized that taking alpha-GPC pre-workout to boost acetylcholine levels can increase muscle power and mental focus. 

This is a relatively new area of research, so more clinical trials are needed. Most of the research done on Alpha-GPC has been with the aging population and improving the cognitive symptoms of individuals with Alzheimer’s

So far, for increasing power output the optimal dose of Alpha-GPC appears to be 300-600mg taken 30-60 minutes prior to exercise. 

Bucked Up contains 200mg of Alpha-GPC, falling shy of what research has shown to be an effective dose for increasing athletic performance.

It is my professional opinion that the dose found in Bucked Up is still likely to support caffeine in increasing mental focus. 


Taurine is an amino acid that plays a key role in energy metabolism and has natural anti-inflammatory and antioxidant properties. 

When taken pre-workout, taurine can increase aerobic (cardiovascular) performance, anaerobic (strength and power) performance, and enhance recovery by reducing feelings of muscle soreness. 

Despite limited research, the current dosing strategy is 1-3g of taurine taken about an hour prior to exercise. 

Bucked Up contains 100mg of taurine, well below what has been used in research to increase athletic performance. 

Deer Antler Velvet

Deer antler velvet is quite literally crushed up antler from deer or elk. It has roots in Traditional Chinese Medicine for general health purposes. 

While the research around deer antler velvet as a means for increasing workout performance is mixed, there is some research to indicate that it might be effective for increasing strength and power output. 

In most dietary supplements, a dose of 500mg daily is used. The few research trials that did show potential for increasing muscular strength and power used doses of 1350mg twice daily. There is insufficient research to establish a clinically effective dose. 

Bucked Up contains 50mg of deer antler velvet extract, which is below any levels used in clinical research trials. 

AstraGin ® 

AstraGin® is a patented product combining notoginseng root and astragalus root. 

AstraGin® was formulated to support gut health, which in turn provides immune support and enhanced nutrient absorption. 

The benefit of increased nutrient absorption is why it is added to pre-workout supplements, since AstraGin® can greatly increase the absorption of amino acids

Recall that citrulline, beta-alanine, and taurine are all amino acids, so it stands to reason that AstraGin® will help increase their absorption. 

The research using AstraGin ® has used doses of 50mg, twice the amount found in Bucked Up, which is 25mg. 

However, since Bucked up has 25mg of a second ingredient called ActiGin® which has more notoginseng root, it’s possible that the combination of AstraGin® and ActiGin® technically provides a clinical dose. 

ActiGin ®

ActiGin® is a dietary supplement formulated to improve energy, endurance and recovery. It is a proprietary blend of notoginseng root and rosa roxburghii, a plant native to the eastern Himalayas, Tibet, and China. 

The companies behind these formulations tend to be a bit secretive about the exact ingredients and mechanisms through which their products work.

The studies highlighted on the ActiGin® page indicate that ActiGin® can increase time to exhaustion, and increase muscle glycogen stores to both increase energy and improve recovery.  

As mentioned above with AstraGin®, a clinical dose of ActiGin® is 50mg, and Bucked Up only offers 25mg.

It’s possible that the combination of 25mg of ActiGin ® plus 25mg of AstraGin ® work synergistically to provide an effective 50mg combination. This is speculation on my part.

Highlights: What I Like About  Bucked Up

Pros vs Cons of Bucked Up Pre-Workout

Good Energy and Focus

Bucked Up uses a very simple blend of caffeine and alpha-GPC to deliver energy and mental focus.

Despite having only two ingredients and a single caffeine source, I found that this product was uplifting and energy boosting without a crash or jitteriness. 

Most pre-workouts now will use a combination of caffeine sources to provide a prolonged energy and minimize the likelihood of a crash afterwards. 

Even though Bucked Up only uses one caffeine source (caffeine anhydrous) I didn’t find that I experienced a significant drop in energy once the product wore off. 

Tastes Good With a Lot of Flavor Variety

With 22 different flavors, there’s no doubt you can find one that appeals to you. Bucked Up offers unique varieties like 

Bucked Up is both sugar free and calorie free, and  uses artificial flavors and sweeteners in its formula. The flavors come in a variety of sweet and sour variations, making it likely that you will find one you like.

For what it’s worth, I tried the Aussi Fruit flavor which is described as Peach Mango, and it was still a bit on the sour/tart side. 

Drawbacks What I Did Not Like About  Bucked Up

Does Not Have Many Clinically Dosed Ingredients

Aside from the 6g of L-Citrulline, and the 2g maintenance dose of beta-alanine, all other ingredients used in Bucked Up either don’t have enough research to establish a clinical dose, or the doses used don’t meet clinical dose standards. 

The result of not using research-backed doses is that you run the risk of the product being ineffective, especially for experienced pre-workout users. 

Honestly, that’s my only real knock against the product. I think the marketing is fun and unique, it tastes great, it’s manufactured in an NSF-compliant facility to ensure quality, and provides feel-good energy. 

Bucked Up just fails to fully deliver on strength and power performance due to the low doses of ingredients like beta-alanine, taurine, AstraGin®, and ActiGin®. 

How Does  Bucked Up Stack Up Against Our Criteria For Pre Workouts

How does  bucked up stack up against our criteria for pre workouts


Our rating: 4/5

Bucked Up comes in at $1.65 per serving, which is right around the industry average of $1.61. While this is good value, the fact that the product does not contain clinical doses of many ingredients lowers the overall value of the product. 

I personally still felt like I got a good workout from Bucked Up, especially compared to other products that fall short of clinical dose standards like C4


Our rating: 4/5

I personally tried the Aussie Fruit (Peach Mango) flavor, and found it enjoyable but still quite tart despite not being a traditionally sour flavor. The selection of 22 different flavors makes me keen to try other options. 

Taste is obviously subjective, but I enjoyed drinking this and didn’t find it overpowering first thing in the morning. I found it a bit sour, but this can be remedied by diluting it with extra water. 


Our rating: 4/5

Bucked Up mixed easily in a shaker cup with 6-8 oz of water. It did have a very slightly gritty texture but not so bad that it took away from the overall experience.


Our rating: 3.5/5

Despite only having 200mg of caffeine, I give this a very high rating for energy because I felt like Bucked Up provided a clean, mood-boosting energy. 

I did not experience any jitteriness or anxiety on this pre-workout, and I didn’t notice any post-workout crash. 


Our rating: 3.5/5

With 6g of citrulline and the addition of AstraGin ® which helps to boost the absorption of citrulline, Bucked Up provides a really decent pump.

The AstraGin ® is technically below clinical dosing standards, but I did find that the 6g of citrulline malate was sufficient to provide a good pump. 

The pump from this product isn’t as intense as other products that use a variety of pump-enhancing ingredients like Pump Serum by Huge Supplements, but still enough to meet most users’ needs. 


Our rating: 3/5

Despite not having high doses of ingredients to support strength and power production, I felt like the energy and mental focus from this product did allow me to push through the final sets and reps of my workout. 

In the same way that Bucked Up provides a good, but not outstanding pump I feel like it also delivers a reasonable, but not outstanding strength boost. 

I also tested Woke AF, a higher-dosed pre-workout offered by Bucked Up that provides more significant increases to strength and pump. This could be a good option (albeit more expensive) for people who want more intense results from their pre-workout. 

If you consider yourself a recreational lifter, then Bucked Up will likely meet your pre-workout needs. 

Who Should Take  Bucked Up? 

Who should take  Bucked Up 

 Bucked Up is for: 

  • People who don’t like strong beta-alanine tingles
  • Individuals who are budget conscious
  • Anyone who is sensitive to food dyes or wants to avoid them in their products for personal reasons
  • Someone looking for a well-rounded product that is not excessively high in stimulants
  • Keto dieters and intermittent fasters

Who Should Not Take Bucked Up? 

I would not recommend Bucked Up for:

  • Anyone looking for a high stim product
  • Those who want clinical doses of key strength and power ingredients like beta-alanine, creatine, and betaine

What Are Other Customers Saying About Bucked Up? 

Bucked Up is well loved across all retail platforms, with ratings between 4.6 and 4.9 out of 5 possible stars. 

The lowest rating I found for Bucked Up came from Amazon, where it had a 4.6 out of 5 star rating with just over 5100 reviews. This is the most reliable sample size I have, since other websites have significantly fewer reviews. 

GNC shows 4.8 out of 5 stars based on 660 ratings and  Bodybuilding.com shows 4.78 out of 5 with 267 reviews. 

Not surprisingly, the Bucked Up website has the highest rating with a score of 4.9 out of 5. The website does not list how many reviews this is based on, though. 

No matter where you shop, the reviews are overwhelmingly positive for Bucked Up Pre-Workout. 

Many users praised the flavor and good energy the product provided, noting that it didn’t cause jitteriness or discomfort. 

Customers were also happy with how easily the product mixed and the fact that it didn’t have large clumps or a significant amount of residue which matches my personal experience with trying it. 

Some users were honest that they missed the “intensity” from higher stimulant pre-workouts and were leaving Bucked Up in favor of its higher caffeine alternative, Woke AF. 

As is typical with any pre-workout reviews, a lot of the negative reviews had to do with product arriving damaged from third party retailers like Amazon. 

I did see a few users reporting nausea or headaches when taking this pre-workout. I always recommend starting with a half scoop serving or trying not to take your pre-workout on an empty stomach if you are prone to nausea. 

Bucked Up Alternatives

Woke AF

Woke AF is another pre-workout offered by Bucked Up. 

It has a lot of similarities to Bucked Up, with the same amount of citrulline, AlphaSize ®, Taurine, Deer Antler Velvet, AstraGin ®, and ActiGin ®. 

Woke AF has higher doses of beta-alanine (3.2g vs 2g) and caffeine (333mg vs 200mg). 

Where Woke AF really jumps to the next level is with the addition of 2 ingredients that act as stimulants and enhance mental focus: synephrine and dendrobium, respectively. 

The end result is a product that delivers a dialed-in mental focus and extreme energy to help you push through your hardest workouts. 

Woke AF does come at a higher price point, costing around $1.83 per serving. While more expensive than Bucked Up, Woke AF is still fairly budget-friendly compared to other high-stim pre-workouts that cost upwards of $2.00 per serving. 

Woke AF is available in 21 different flavors, nearly identical to those offered by Bucked Up. 

Transparent Labs Bulk

Transparent Labs Bulk

If you are the kind of pre-workout user who values clinical doses of strength and endurance-enhancing ingredients as opposed to high doses of stimulants, then Transparent Labs Bulk is a fantastic alternative. 

Bulk comes at the same cost as Bucked Up ($1.66 per serving) and has the same 200mg of caffeine. 

Where Bulk really shines is in its high, clinical doses of ingredients like citrulline (8g), beta-alanine (4g), betaine (2.5g), taurine (1g), and Alpha-GPC (300mg).

This is in contrast to Bucked Up which does have most of the same ingredients but at significantly lower doses. 

The end result is that Transparent Labs Bulk provides phenomenal strength, endurance, and mental focus at a reasonable cost. 

Bulk does not use any artificial sweeteners or colors and is Informed Choice Certified, meaning the ingredients and the lab undergo rigorous third-party testing. 

Transparent Labs Bulk is available in 8 different flavors: Strawberry Kiwi, Pina Colada, Blue Raspberry, Black Cherry, Peach Mango, Tropical Punch, Sour Grape, and Watermelon. 

Are There Any Promos or Discounts For Bucked Up? 

I could not find a subscribe and save feature that many other companies offer online. This is where you can set your supplement purchase to auto-ship at predetermined intervals (e.g. every 30 days) and you save anywhere from 5-30% off your products. 

Bucked Up does have a page dedicated to pre-built stacks which allows you to save some money. Here, they put together a collection of 3-6 supplements based on your fitness goals and offer them at a discount. 

Bucked Up also has a clearance page on their website where you might be able to catch some deals on flavors that are making their way out of circulation. 

Since Bucked Up is available at various retailers like GNC and The Vitamin Shoppe, you may be able to save money when those retailers offer sales or promotions in-store.
