Experience Using Cellucor Creatine 

The typical serving of this product is one scoop daily mixed with 8 ounces of cold water (or beverage of choice) before, during, or post-workout. Since it’s unflavored, you could mix it with a protein shake or pre-workout. 

A loading phase is recommended for anyone not already using a creatine supplement, which involves taking 4 servings daily for the first 5 to 7 days. The intention of loading is to saturate muscle cells with creatine for quick results.

“I tried this creatine and thought it was a solid, run-of-the-mill option. It has all the right stuff in the right dosages and would be a good option for anyone looking for a creatine supplement,” says GGR tester Anthony O’Reilly.

With only one ingredient, creatine monohydrate powder, you aren’t ingesting other unnecessary ingredients, like added sugar or ingredients you may already be taking in your pre-workout supplement. 

Ultimately, Cor-Performance Creatine keeps it simple with a single ingredient in the most effective amount, meaning you’re more likely to see the power, strength, and muscle gains you desire.

Price Per Serving

At the time of writing, Cellucor Cor-Performance costs $29.99 on Amazon. Every container contains 72 servings. A single serving is one scoop and costs approximately 42 cents. If you’re looking for an affordable product that will last up to 10 weeks, this may be a good choice for you.

Compare this to Thorne Creatine Monohydrate, which sells for $39.95 on Amazon and includes 90 servings for approximately 44 cents per scoop. 


Cor-Performance Creatine contains creatine monohydrate. There’s nothing more to it! This product doesn’t include artificial ingredients, sweeteners, or stimulants commonly found in other supplements. Although the ingredients list is short, that doesn’t mean this product doesn’t pack a punch. 

Creatine is an amino acid derivative produced by the body in very small amounts and found in foods like salmon, herring, tuna, beef, and pork. Many athletes supplement with creatine because it increases the available fuel to power the body’s ATP levels (energy) for enhanced exercise performance. 

Cellucor Creatine 3

Creatine monohydrate is the most-studied, affordable, and effective form of creatine available. This form of creatine is most similar to the creatine naturally made by the body. 

RELATED: Creatine Benefits

As mentioned previously, creatine monohydrate has been shown to improve strength, muscle growth, and power1. Additionally, creatine may help with post-exercise recovery and injury prevention. 

Research1 shows that 3-5 grams of creatine monohydrate daily is ideal for keeping muscle creatine stores fully saturated. Cor-Performance Creatine includes 5 grams of creatine monohydrate per serving, so you can consume enough daily to gain the full benefits.  

Taste and Solubility 

Cellucor boasts the water solubility and micronization of Cor-Performance Creatine, claiming that this product has superior mixability. “This is very powdery! It’s almost like talcum powder! Very foamy upon mixing this up in a shaker cup; but it does dissolve completely,” confirms Anthony.

The product is unflavored creatine, however, many Amazon reviewers claim it has a slightly chalky taste. 

Side Effects

Evidence suggests that creatine supplementation is generally well tolerated, especially at doses of 3-5 grams per day2

Water retention from increased intracellular volume may occur during the first few days of taking a creatine supplement, but this is generally not an ongoing side effect2. Short-term water retention may lead to GI distress and feeling bloated.

It’s a common concern that creatine supplementation leads to kidney damage due to increased creatinine in the blood which must be excreted through urine. However, evidence indicates that people with healthy kidneys can filter out creatinine without causing damage2.

One 2003 study3 reported that football players who supplemented 5 to 10 grams of creatine daily for 21 months saw no significant effects on markers of kidney function like creatinine clearance. 

Another randomized, double-blind, placebo-controlled trial4 found that patients with Type 2 diabetes who took a creatine supplement for 12 weeks did not experience significant differences in creatinine clearance and other kidney function markers compared to the placebo group. 

Third-Party Testing 

Although some Cellucor supplements are third-party tested, Cor-Performance Creatine is not one of them. The Food and Drug Administration does not approve dietary supplements for safety and effectiveness before they go on the market. For this reason, we encourage third-party testing to ensure a product is free of heavy metals, allergens, and banned substances.

Bottom Line

Thorne Creatine provides 5 grams of creatine per scoop. They recommend taking it in the morning to improve brain performance or near a workout to help improve muscle strength and size. Customer reviews of this product are generally positive, although Thorne has changed their formula recently due to supply chain issues, and some long-time users do not like the new version as much.

Thorne Creatine and Cellucor Creatine are very similar products. Thorne Creatine is another single-ingredient creatine monohydrate supplement. Each serving (1 scoop) contains 5 grams of creatine. Therefore, both products use the same form of creatine in the same amount per scoop. 

Both supplements used micronized creatine for superior mixability and solubility. Additionally, they are each unflavored and uncolored. 

Unlike Cellucor’s creatine product, Thorne Creatine is third-party tested. As an NSF Certified for Sport product, athletes can trust that Thorne Creatine is free of over 200 banned substances and that they are getting the formulation advertised on the product label. 

Thorne Creatine also comes with more servings per container than Cellucor Creatine at 90 and 72 servings respectively. Both products are similar in price per serving, with Cellucor costing 2 cents less per scoop than Thorne. 

If you’re looking for a third-party tested product, Thorne Creatine is the appropriate choice. For the best deal, consider Cellucor Cor-Performance Creatine.

Customer Reviews

This product has a rating of 4.6 out of 5 stars on Amazon and 4.9 out of 5 stars on the Cellucor website.

One customer appreciates the simplicity and affordability of Cellucor creatine. “Take it from someone who has been lifting weights for 10+ years, this is the creatine you need. Very cost-effective, just pure creatine monohydrate. It doesn’t give you an energy burst or have any hint of flavor, so you can mix it with any drink at any time of day without worrying about it keeping you up at night.”

Another customer claimed it’s easy to mix but didn’t completely dissolve. “It is easy to mix with my pre-workout and it did not change the flavor in any way. I even mixed it with plain water to see if there was any flavor, there was none. My only gripe about it is that it doesn’t completely dissolve. There is still some grittiness after using a shaker bottle with room temp water. I would still happily purchase this product again.”

Final Verdict of Our Cellucor Creatine Review

Cellucor Cor-Performance Creatine is a no-fuss supplement containing only the most researched form of creatine to take your gains to the next level. Made with creatine monohydrate, an amino acid derivative that helps synthesize energy needed for exercise, this product may improve muscle strength, size, and power. 

Cellucor Cor-Performance is a good option for someone looking for a budget-friendly creatine supplement without any stimulants, artificial sweeteners, or dyes. It’s not the best option if you’re looking for a third-party tested product.
