Experience Using GNC Amp Creatine HCL 189
One serving of Creatine HCL 189 is two tablets. The tablets are large and should be taken with plenty of water. The outer casing is slick, making it easier for some to swallow. Even so, many customer reviews on Amazon complain that they are too big and uncomfortable to swallow.
RELATED: How Much Water Should You Drink with Creatine?
“These are HORSE PILLS! Pretty big, and you need to take two pills for a serving. However, I found them OK to swallow,” says product tester Anthony O’Reilly.
GNC Amp encourages you to take these tablets at a time that’s convenient for you, perhaps when taking a multivitamin or pre-workout. Creatine is effective before, during, or after a workout. Unlike ordinary creatine supplements, this creatine HCl product doesn’t require a loading phase.
RELATED: Best Pre-Workout Without Creatine
Otherwise, there’s not a whole lot to say about taking a creatine supplement in tablet form. The directions are clear, easy to follow, and if you can manage to swallow the pills, then that’s really all there is to it.
Price Per Serving
It is much less expensive to purchase this product off Amazon rather than the GNC website. At the time of writing, you save a whopping $17.00 when you buy this GNC creatine from Amazon.
You can purchase Creatine HCL 189 on Amazon at a reduced price of $27.99 for a two-month supply. For 120 tablets, you pay 0.23 cents per pill. Since a serving is two tablets, this comes out to be 0.46 cents a serving.
There is also the option to purchase a four-month supply for $64.99 on Amazon. For 240 tablets, you pay 0.27 cents per pill and 0.54 cents a serving.
Formulation
PEG Creatine HCL is the main ingredient in Creatine HCL 189. GNC Amp claims this form of creatine is better absorbed, more efficient, and of higher quality than creatine monohydrate, the most studied form sold today.
Although GNC refers to a clinical study to back up these claims on their website, they do disclose they performed the research themselves and don’t offer links to the original research.
GNC Amp boasts the results of a randomized, double-blind study of 57 males that indicated those who supplemented with GNC Amp Creatine HCL 189 containing 1.25 grams of PEG creatine HCL significantly improved their leg press one-rep max by 54.3 pounds compared to subjects taking 5 grams of creatine monohydrate who increased their performance by 52.3 pounds.
In the very few human studies completed on creatine HCL, one randomized, double-blind study1 observed 40 individuals complete 4 weeks of weightlifting while taking either creatine HCL or creatine monohydrate. Both creatine supplements improved exercise performance, but only creatine HCL was associated with body composition changes.
Although these results sound impressive, GNC’s research can’t be verified. Many more independent clinical studies are needed before we can confidently suggest that creatine HCL is superior to other forms of creatine. In fact, most current research shows that the most effective form is creatine monohydrate, according to a 2022 systematic review2 in the Journal of Strength and Conditioning Research. It’s also of note that GNC Amp Creatine HCL 189 is dosed at 1.25 grams, which is significantly below the recommended amount of 3 to 5 grams per day.
RELATED: How To Take Creatine
Following creating HCL, calcium is the next on the ingredient list, which research3 shows may help increase blood creatinine concentration. Creatinine is a byproduct of creatine that helps boost muscular energy. Most other ingredients included are used to make this product into a pill form. For instance, microcrystalline cellulose is used as a binder in wet and dry manufacturing processes. Enteric coating is a polymer barrier used to form the outer shell of a pill.
Note that a natural mint flavor and sucralose (an artificial sweetener) are included in small amounts. Some Amazon customers mentioned a slightly minty taste.
Taste and Solubility
GNC states on its website that creatine HCL has superior solubility compared to other forms of creatine. Creatine HCL is thought to be 41 times more soluble in water than creatine monohydrate1. This could mean that creatine HCL can be better absorbed into the bloodstream, potentially resulting in greater muscle creatine uptake and effectiveness, though the research on this is limited.
Although the supplement is considered unflavored, the tablets have a slight mint flavor. Keep in mind these tablets are intended to be swallowed, not chewed, so you probably won’t notice much of the mint flavoring.
Side Effects
Creatine supplementation is generally well tolerated, however the most commonly reported side-effects include water retention and GI distress.
During the first few days of taking a creatine supplement, you may retain water due to increased intracellular volume3. Typically this is a short-term side-effect that resolves on its own. However, it can be accompanied by GI distress and feeling uncomfortably distended.
That said, since creatine HCL is thought to be more soluble and easily absorbed than other forms of creatine, these side effects may be less likely1.
It’s a common fear that creatine supplementation causes kidney damage from elevated creatinine in the blood that must be expelled through urine. However, research has found4 that those with healthy kidneys filter out creatinine without causing damage.

Third-Party Testing
GNC Amp Creatine HCL 189 is not third-party tested. Keep in mind, the Food and Drug Administration does not approve dietary supplements for safety before they’re sold in stores. That’s why we encourage third-party testing to ensure a product is free of heavy metals, allergens, and banned substances.
Comparison to Con-Cret Creatine HCL
GNC Amp Creatine HCL 189 and Con-Cret Creatine HCL contain the same form of creatine in different amounts. A serving of Con-Cret Creatine HCL includes 750 milligrams of creatine HCL, compared to Creatine HCL 189, which includes 1,250 milligrams.
Con-Cret Creatine HCL is available in both powder and tablet form. The powder form is available in many different flavors, including fruit punch and lemon-lime. Con-Cret Creatine claims to be the most bioavailable creatine.
Whereas Con-Cret Creatine HCL powder would need to be mixed with water and consumed as a liquid, Creatine HCL 189 is simply swallowed in pill form. Some customers prefer the ease of taking a pill, while others would rather sip on a flavored drink.
Con-Cret Creatine HCL powder is made with fewer ingredients, only including natural flavors and stevia leaf extract. Both supplements are free of stimulants.
Creatine HCL 189 is more expensive based on the price per serving. Creatine HCL 189 costs 0.46 cents per serving, compared to Con-Cret Creatine HCL powder at 0.39 cents per serving.
If you prefer a creatine HCL product in powder form, made with natural flavors, and offered in several flavors, then Con-Cret Creatine HCL is your best bet. On the other hand, if you like the convenience of taking creatine HCL in tablet form then Creatine HCL 189 may be for you.

Customer Reviews
This product has a rating of 4.6 out of 5 stars on Amazon and 4.2 out of 5 stars on the GNC website.
One Amazon customer noticed enhanced strength: “Every time I start taking it my bench and squats go up 20 lbs almost immediately. Really lets you lift more to build more. It can be daunting to swallow these horse pills at first, but once you get used to it it’s no big deal. Results are worth it!”
Another GNC customer mentions difficulty swallowing the tablets: “I’m definitely stronger and less fatigued when taking them, but they are pretty big pills and hard to swallow. So far, I’ve had no issues with water retention or bloating. On the whole, I think these are good value for your money.”
Final Verdict of Our GNC Amp Creatine HCL 189 Review
GNC Amp Creatine HCL 189 may benefit weight lifters interested in gaining strength and enhancing muscle power and endurance during an intense workout. Although GNC makes some convincing claims that creatine HCL is superior to competing products made with creatine monohydrate, their claims lack sufficient research and evidence.
Creatine HCL 189 tablets are large and difficult to swallow but have superior solubility and may absorb better than other forms of creatine. Many customers report having less GI distress when taking Creatine HCL 189 tablets compared to other creatine supplements. If you like the convenience of taking your supplements in tablet form, you could give this product a shot.
