  • The Power of 5g of Creatine in 2 Tablets
  • 400% Increase in Dose Efficiency to Enhance Athletic Performance*
  • Increases Strength With Only 25% of the Dose of Ordinary Creatine*
What is Amplified Creatine 189™?
Looking for the creatine? We’ve got it. Amplified Creatine 189™ is a cutting-edge solution that tops ordinary creatine monohydrate. In fact, it’s proven to get into your muscles and improve strength more efficiently.* Don’t just take any creatine. Tear it up with Amplified Creatine 189™.

The Amplified Creatine 189™ Evolution
It all started with basic science. Everyone knows creatine works to improve athletic performance.* The question is- how did we AMPlify its effects.

PEG-Creatine System™- This proprietary formula includes a patent-pending technology which allows you to get the same benefits as regular creatine monohydrate at a much lower dose! That’s right, you no longer have to take mounds of powder or handfuls of creatine pills to get the performance enhancing benefits of creatine.

The Proof is in the Muscle
We tested it and have proof that Amplified Creatine 189™ gets into muscle- even better than ordinary creatine! In a clinical study, Amplified Creatine 189 resulted in 189% muscle creatine uptake relative to creatine monohydrate.* Users of Amplified Creatine 189™ take less creatine and get more into the muscle.*

Health Notes

Creatine Monohydrate

Creatine Monohydrate
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Chronic Obstructive Pulmonary Disease
Dose: 5 grams three times a day for two weeks, and then 5 grams once daily
Creatine has been shown to increase muscle strength, muscle endurance, and overall health status.(more)
High Cholesterol
Dose: Refer to label instructions
One trial found that supplementing with creatine significantly lowered serum total cholesterol and triglycerides in people with high cholesterol.(more)
High Triglycerides
Dose: Refer to label instructions
One trial found that supplementing with significantly lowered serum total triglycerides in both men and women.(more)
Athletic Performance and Non-Weight Bearing Endurance Exercise
Dose: 15 to 20 grams daily for five or six days
Taking this supplement for five or six days may improve performance of high-intensity, short-duration exercise (like sprinting) or sports with alternating low- and high-intensity efforts.(more)
Athletic Performance and High-Intensity, Short Duration Exercise or Sports with Alternating Low- and High-Intensity Efforts
Dose: 15 to 20 grams a day for five or six days
Supplementing with creatine may improve performance of non-weight bearing endurance exercises such as cycling.(more)
Chronic Obstructive Pulmonary Disease
Dose: 5 grams three times a day for two weeks, and then 5 grams once daily

In a double-blind study, people with COPD received creatine or a placebo for 12 weeks. After the first 2 weeks of supplementation, all participants underwent an outpatient pulmonary rehabilitation program. Compared with the placebo, creatine significantly increased muscle strength, muscle endurance, and overall health status, but not exercise capacity.1 The amount of creatine used in this study was 5 grams three times a day for 2 weeks, and then 5 grams once a day for 10 weeks.

High Cholesterol
Dose: Refer to label instructionsA double-blind trial found that 20 grams per day of creatine taken for five days, followed by ten grams per day for 51 days, significantly lowered serum total cholesterol and triglycerides, but did not change either LDL or HDL cholesterol, in both men and women.1 However, another double-blind trial found no change in any of these blood levels in trained athletes using creatine during a 12-week strength training program.2 Creatine supplementation in this negative trial was lower-only 5 grams per day were taken for the last 11 weeks of the study.

Athletic Performance and Non-Weight Bearing Endurance Exercise
Dose: 15 to 20 grams daily for five or six days

Creatine (creatine monohydrate) is used in muscle tissue for the production of phosphocreatine, a factor in the formation of ATP, the source of energy for muscle contraction and many other functions in the body.1, 2 Creatine supplementation increases phosphocreatine levels in muscle, especially when accompanied by exercise or carbohydrate intake.3, 4 It may also increase exercise-related gains in lean body mass, though it is unclear how much of these gains represents added muscle tissue and how much is simply water retention.5

Over 40 double-blind or controlled studies have found creatine supplementation (typically 136 mg per pound of body weight per day or 15 to 25 grams per day for five or six days) improves performance of either single or repetitive bouts of short-duration, high-intensity exercise lasting under 30 seconds each.6, 7, 8, 9, 10, 11, 12 Examples of this type of exercise include weightlifting; sprinting by runners, cyclists, or swimmers; and many types of athletic training regimens for speed and power. About 15 studies did not report enhancement by creatine of this type of performance. These have been criticized for their small size and other research design problems, but it is possible that some people, especially elite athletes, are less likely to benefit greatly from creatine supplementation.13

Fewer studies have investigated whether creatine supplementation benefits continuous high- intensity exercise lasting 30 seconds or longer. Five controlled studies have found creatine beneficial for this type of exercise,14 but one study found no benefit on performance of a military obstacle course run.15 Most studies of endurance performance have found no advantage of creatine supplementation, except perhaps for non-weight bearing exercise such as cycling. 16, 17, 18

Long-term use of creatine supplementation is typically done using smaller daily amounts (2 to 5 grams per day) after an initial loading period of several days with 20 grams per day. Very little research has been done to investigate the exercise performance effects of long-term creatine supplementation. One study reported that long-term creatine supplementation improved sprint performance.19 Four controlled long-term trials using untrained women,20 trained men,21 or untrained older adults found that creatine improved gains made in strength and lean body mass from weight-training programs.22, 23 However, two controlled trials found no advantage of long-term creatine supplementation in weight-training football players.24, 25

Creatine supplementation appears to increase body weight and lean body mass or fat-free mass, but these measurements do not distinguish between muscle growth and increased water content of muscle.26, 27 A few double-blind studies using more specific muscle measurements have been done and found that combining creatine supplementation with strength training over several weeks does produce greater increases in muscle size compared with strength training alone.28, 29, 30

        I'm happy with this product and has no side effects!!!! It is a little weak for me and everyday powerlifting and bodybuilding but when stacked with other supplements it helps.

          I have been working out without Creatine for about 5 years now. I wish I would have discovered using this when I started. I have been at a stuck point for a few months now, and I discovered this product. Within a week and a half I have seen immediate gains in my weight with everything I am doing. Great product that actually works with no side effect. If your looking for real results this is one thing you definitely need to be adding to your stack.

          I decided to try this on sale about 2 weeks ago. I have currently been on it for a week and can already see results during and after my workouts. It helps both with workouts and recovery. Personally I have found it useful to cut the pills in half so that they digest easier and to take them with juice (or any other sugary drink) so that they metabolize better. I have already recommended this to a friend and will probably recommend to more.

              I defiantly notice the difference. but it seems to give if taken regularly for to long.

                  Comments about GNC Pro Performance® AMP Amplified Creatine 189™:

                  I take the recommended 2 pills per day. Gains seem to come regardless of taking them before, during, or after workout. No side effects detected, unlike other forms of creatine. I have been a regular at the gym for about 20 years (5 days per week - cardio and lifting) and had my share of plateaus, and setbacks. I have had slow, but very steady gains with this stuff over the last couple of months, without change in diet or workout. I am now exceeding my previous max on biceps, shoulders, and quads. The rest is following right behind. At this cheap of a price for a 2 month supply, it is more than worth trying, to see if it works for you.
