Creatine supplementation is effective for beginners and for people with more developed muscle, but beginners often notice the impact sooner because they’re stacking it on top of rapid early training improvements.
For a beginner, adding creatine can make hard sets feel more repeatable—more quality reps, more consistent effort, and more training you can recover from. That matters because early progress is often limited by practice, consistency, and the ability to keep showing up with intent.
For someone more experienced, creatine still supports training quality—but the “wow” factor can feel smaller because training is already dialed in and progress comes in tighter increments. In other words: the benefit is real, but it’s easier to overlook when you’re chasing smaller, more measured gains.
At GNC, the goal is simple: choose a creatine you’ll take daily, pair it with progressive resistance training, and give it enough time to show up in your workouts—because that’s where results are built.
The biggest difference isn’t whether creatine “works”—it’s what you’re able to do with it.
Beginners typically have more room to improve across the board: technique, consistency, and basic strength. When creatine supports training intensity, it can help a beginner keep sessions more productive. That often looks like finishing your sets with better form, pushing one more rep at the same weight, or keeping performance steadier across the week.
More developed lifters are often already training close to their current capacity. Creatine can still help maintain training quality, especially during demanding phases (higher volume blocks, heavier strength work, or when trying to add reps while keeping rest times honest). The difference is that advanced progress tends to be incremental—so improvements may show up as small performance edges that compound over time.
One more important point: the more consistent your training and nutrition are, the easier it is to notice what creatine is contributing. If your workouts, protein intake, and sleep are all over the place, creatine can’t “outwork” that foundation.
Most people don’t “feel” creatine like a stimulant—you notice it in performance patterns: sets that stay strong, reps that come easier at the same load, and training that feels more repeatable week to week.
If you’re a beginner, the first thing to look for is consistency across sets (less drop-off) and more total work across the session. If you’re more advanced, you may notice better repeatability at higher loads, or that you can hold performance steady when volume climbs.
What not to do: judge creatine by a single workout. Track your main lifts (or key movements) over several weeks. When creatine is working for you, it helps you string together more high-quality training—and that’s the real driver of change.
GNC carries creatine options that fit different preferences (powders, capsules, tablets). The best choice is the one that makes daily use effortless.
If you want the most straightforward, widely used option, creatine monohydrate is the classic starting point. It’s simple, mixes into drinks, and is easy to build into a daily routine.
If you prefer tablets and a smaller daily amount, GNC AMP Creatine HCl 189™ is formulated around a PEG-creatine system and is positioned as offering improved absorption vs. regular creatine monohydrate, with benefits at a lower dose per serving compared to ordinary creatine.*
The best pick depends on how you’ll actually take it:
Either way, think “daily consistency” first. That’s what turns supplementation into results you can measure in your training.
The most effective creatine routine is the one you can follow every day.
Start by choosing one daily time anchor: with breakfast, post-workout, or alongside your regular supplements. Then keep it consistent. Creatine is often discussed in terms of timing, but day-to-day adherence is what matters most for building a reliable routine.
If you’re training hard and you want to keep things straightforward, pair creatine with the basics:
GNC’s job is to help you curate that foundation—so you can spend less time overthinking and more time putting in quality work.

Great taste
The "New" flavor is not as good as the previous. It's way too sweet. I've begun using a more natural protein powder that doesn't have all the sweeteners. Sorry. Been a customer for many years, but it's time to change as I can't get past this issue.
4.5 rating for texture, taste and causes no GI issues.
Wow I just had to open a new container and realized it was different. This new formula is awful I have used this protein for years to make a protein cake for dessert..well this formula won't cook at all. It is awful?I don't know what to use now and I just threw $60 out the window because i can't use this gnc new protein formula. Think twice before purchasing this. I will not be ordering this again
Taste horrible compared to old sustained cheaper ingredients and on top of that the jug is taller but less protein in it same price that is DESEPTIVE to loyal gnc customers Definitly gonna shop around for protein I'm done with gnc games
Terrible Will not buy again the formula has changed and I have been using this product for years.
My favorite protein for morning shakes! Plastic jug has gotten larger and servings have gotten smaller though. A bit deceptive.
Formula change for the WORST. The old formula had quality isolate ingredients and the new has cheap whey ingredients. New formula tastes sour and leaves an awful aftertaste. We sincerely thought we bought an expired batch until we compared ingredients. The old formula was creamy, sweet and perfect for smoothies. We won't be buying from GNC until they bring back the old formula.
I've been through probably 8 -10 containers of this powder - prior to the flavor change. I really used to look forward to having this, but not anymore. It tastes like fruit loops were added to it. Very disappointed. Also, I see that you have reduced the number of servings per container. I understand that costs can go up, but why be sneaky about it?
Formula was recently changed (vainilla milkshake) and now it tastes like every other protein shake, horrible aftertaste. I was so happy with the previous one.
