Promix Creatine Review (2025): Clean, Effective, and Affordable In Bulk

Athletes across the globe are always looking for high-quality supplements to aid them in their sports nutrition and performance—from multivitamins to whey protein powder and the best creatine.

Creatine is the most researched supplement in the market and is widely popular due to its connection with improved muscle growth and sports performance¹—particularly among athletes. Still, athletes often prefer a clean, third-party-tested supplement without many fillers.

Promix Micronized Creatine delivers on this, providing a pure, clean creatine monohydrate without any fluff. In this Promix Creatine review, I’ll go over the formulation of this creatine supplement to see if it’s the right addition to your current supplement stack. Read on to see if this creatine powder is worth its cost.

Over 50 Creatine Supplements Tested

That’s right, over 50 creatine powders and supplements have been tested and used by our expert team at Garage Gym Reviews—more if you include the best pre-workout with creatine. The team here consists of certified personal trainers, nutrition coaches, and athletes all living and breathing fitness. Additionally, we talk with registered dietitians to get the facts on supplements.

I myself, being a certified nutrition coach and an Olympian in the sport of weightlifting, tested out Promix Creatine along with GGR Staff Writer Matt Dustin, CES, PN1-NC. In trying out the unflavored creatine, we rated certain aspects of the powder, scoring it between a 1 and 5 based on our supplement testing methodology, including:

• Formulation
• Price per serving
• Solubility
• Taste
• Side effects
• Third-party testing

Bottom Line

Promix Micronized Creatine offers a non-GMO creatine monohydrate. It’s unflavored and can be mixed with pre-workout or protein powders. While the website shows the third-party testing results for this Promix Micronized Creatine product, it doesn’t offer the name of the independent lab where it was tested.

A Quick Look at Promix Creatine

According to an in-house supplement trends study, while interest in protein and strength supplements has declined over the last decade, creatine has seen a boost in interest. Based on Google searches between 2022 and 2023, there’s been an uptick of over 23% for the search term “best creatine supplement.” With the growing interest and the general boom of the supplement market size, it’s no wonder that creatine is such a sought-after supplement.

A quick glance at Promix’s website will tell you that they take their supplements seriously—including protein powder, multivitamins, and an electrolyte drink mix. All their products are based on the latest research, and each supplement is also extensively tested by athletes for athletic performance and building muscle.

Promix Micronized Creatine looks to be made with the same scrutiny, as it is NSF Certified for Sport and a verified non-GMO creatine. Additionally, the gluten-free creatine is micronized, which is a process that reduces the particle size of creatine powder further, allowing for easier absorption. There are no artificial flavors or artificial ingredients; this is just creatine monohydrate.

Before You Buy

• Although the creatine is third-party tested and certified by NSF, there’s no apparent labeling on the container. Rest assured, it’s listed on the NSF Sport website.
• Promix also boasts some sustainable practices, which isn’t a common point from supplement companies. Promix says they use 67% less carbon than similar products, and about 94% of their ingredients are sourced from North America.
• Although Promix comes in 30- and 180-serving bags, I recommend getting the 180-serving bag. It drastically reduces the price per serving, by over $0.50 each serving.
• You can also save on each bag of Promix by subscribing to deliveries of the supplement once every month, 2 months, or 3 months.

Is Promix Creatine Worth It?

Going off purity alone, Promix is worth it, going under strict scrutiny to ensure that the micronized creatine is high-quality and free of banned substances for athletes. Additionally, it’s free of any GMOs or artificial sweeteners and ingredients; it’s simple and clean.

That said, I think Promix Creatine is most worth it if you buy in bulk. Currently, you can get Promix in a 30- or 180-serving bag. The 30-serving bag is $29, which comes out to $0.87 per serving. The 180 servings come in much cheaper, with a $59 bag costing about $0.32 per serving on a one-time purchase…one of the lower prices per serving I’ve seen in creatine. With third-party testing and non-GMO verification, it’s quite a deal.

Being one of the highest-quality creatine supplements we’ve come across, this is a great option and a great price for athletes or fitness enthusiasts who want creatine without any extra fluff. Still, people may not want to buy in bulk, or may just be interested in the lowest price possible—with or without the assurance of third-party testing.

Experience Using Promix Creatine

GGR Staff Writer Matt Dustin, CES, PN1-NC, and I tried out Promix creatine over several weeks, taken with water, in a protein shake, or in an electrolyte drink. Typically, I took creatine prior to my workouts, although post-workout and other times are fine. 

If you’ve had a single-ingredient creatine powder before, Promix creatine will be very similar. The white powder is unflavored, although it’ll still have a slight aftertaste. I hardly noticed it (which is rare for creatine), but Matt noticed a slight bitterness when mixed with water. “The flavor disappears when you mix it with a protein drink, though,” he adds.

Creatine helps in adenosine triphosphate (ATP) production, replenishing ATP stores² used in explosive movements like sprinting and heavy lifting. While I never noticed a difference between Promix creatine and other creatine monohydrates I’ve used, I do feel like creatine generally helps me push a little more during workouts—like I can give a little more effort on each repetition. Promix Creatine provided the same feeling during my workouts.

Let’s break down our ratings and scores for this creatine supplement.

Price Per Serving

I rate the price per serving a 5 out of 5, with a bit of a caveat: the 5-out-of-5 score is for the bulk 180-serving bag. This big bag costs only $0.32 per 5-gram serving—less if you opt for a subscription. However, getting the 30-serving bag bumps the cost to $0.87 per serving, which is far less of a deal for creatine monohydrate. Based on this higher price alone, the creatine would probably score only a 3.5.

Promix does offer creatine sticks that are packaged similarly to electrolyte or hydration packets. However, 30 sticks come out to nearly a dollar per stick. For the best deal, buy in bulk from Promix.

Formulation

The recommended daily dosage of creatine is between 3 and 5 grams³ to get the most creatine benefits, and Promix Creatine hits that mark with flying colors. A serving size of Promix Creatine is 5 grams, purely of creatine monohydrate—the most researched type of creatine. Because of an effective dose and no fillers or added junk, Promix gets a 5 out of 5 for its formulation. 

Taste and Solubility 

Promix Creatine scores a 4 out of 5 for both its taste and solubility. The creatine supplement is unflavored, and compared to other creatine supplements, I thought it was fairly accurate. Many creatine supplements can have a bitterness to them, and while Matt noticed the flavor when mixed with water, we both agreed that the flavor disappears when mixed into a protein shake or smoothie. I was impressed, as that’s sometimes still not enough for some creatine powders.

As for its solubility, Promix Creatine is micronized, meaning that the granules are further processed into smaller granules, which makes it easier to mix. However, I’ve never known a creatine supplement to completely dissolve, and Matt had the same issue. “It mixes very well,” he says, “but after some time, some powder settles to the bottom.”

Side Effects

Matt and I didn’t notice any side effects from taking Promix Creatine, earning it a 5 out of 5 for side effects. We both take creatine fairly regularly, however, so we’re pretty used to the powder. If you’re new to creatine, I recommend taking it in the recommended amount, 3 to 5 grams, as research has shown⁴ larger doses increase your chances of digestive issues or weight gain (in the form of water retention).

Generally speaking, as long as you keep to the recommended dosage of 3 to 5 grams (even in a creatine loading phase), your risk of creatine side effects will be substantially lower.

Third-Party Testing 

Although there’s no apparent labeling on the actual container, I did a bit of digging online and found that Promix Micronized Creatine is NSF-Certified for Sport, on the official NSF Sport website. 

While I’d still like to see a badge on the container just for ease of reference, athletes can rest assured that this creatine has been third-party tested for banned substances by the National Sanitation Foundation—the third-party testing certification that the United States Anti-Doping Agency recommends. For this reason, Promix gets a 5 out of 5 for its third-party testing.

Additionally, Promix Creatine is verified as a non-GMO product by the Non-GMO Project.

GGR Score: 4.8

Product Highlights

• 5 grams of creatine monohydrate per serving
• Less than $0.50 per serving
• Third-party certified
• Unflavored

Pros & Cons

Pros

• Affordable
• Easy to mix
• Research-backed dose of creatine
• Third-party certified
• Subscribe and save options

Cons

• No flavor options
• Some reviews say it doesn't mix or dissolve well

Bottom Line

Our testers love Sports Research Creatine Monohydrate because it's less than 50 cents per serving, is truly tasteless, and is third party-certified so athletes can take it knowing there's no junk inside.

While Promix Creatine in bulk is a pretty great deal—due to third-party testing and purity—another great creatine option for athletes and people looking for clean, minimal ingredients is Sports Research Creatine Monohydrate. This creatine supplement rivals Promix in just about every way. Sports Research also does third-party testing for banned substances—through Informed Sport—and also keeps the ingredients list minimized to pure, micronized creatine monohydrate.

Sports Research Creatine comes in 60 or 100 servings, and the price per serving actually beats Promix’s bulk 180-serving bag, coming in at $0.30 or lower.

While the prices are somewhat comparable, if you’re looking for the best deal, Sports Research is a quality, third-party-tested creatine powder at a surprisingly low cost. Promix Creatine may be the better option if you’re simply looking for a single purchase that’ll last longer, or if you prefer NSF certifications over Informed Sport, since the United States Anti-Doping Agency (USADA) only recommends NSF-Certified for Sport for third-party testing.

Either way, both products are solid, clean, and pure creatine supplements. You won’t go wrong with either one.

Customer Experience 

Promix earns a 4 out of 5 for its customer service. While they boast an impressive 90-day money-back guarantee, the company will take 10% for shipping costs and restocking fees. Additionally, there is only one way I could see to contact the company, and that is an online form on the website. For more minor questions, however, there is a fairly sizable FAQ section.

Ordering Promix Creatine

Promix Micronized Creatine is available on both their website and through Amazon. Amazon’s price is a bit higher, but shipping is free with an Amazon Prime membership. Still, a subscription through Promix drops the price and gives you free shipping, so Promix’s website can save you just a bit more. Neither Promix nor Amazon provides financing or split payment options.

Customer Reviews

As of this writing, Promix Non-GMO Creatine has an average of 4.7 out of 5 stars on Amazon (out of 260 reviews), and 4.9 out of 5 stars on the Promix website (out of 163 reviews). Reviews are overwhelmingly positive, with many people appreciating its effects on their workouts, as well as the fact that it’s flavorless. One 4-star review, however, does wish the creatine was more soluble.

Most negative reviews have to deal with the solubility or packaging issues. Multiple customers received a bag with no scoop (this didn’t happen to me or Matt). A 1-star review actually had the bag damaged in shipping, followed by a lackluster experience with customer service, where they were simply told to transfer it to another container.

Final Verdict of Our Promix Creatine Review

If you’re looking for a solid, clean, and simple creatine supplement, Promix Creatine is a solid option—so long as you buy in bulk. If you want less than 180 servings, there are plenty of other options with cheaper prices per serving. However, keep Promix in mind if you’re looking for any of the following things in your creatine supplement:

• You’re buying in bulk
• You’re looking for a third-party tested supplement
• You need a creatine powder with minimal ingredients
