  • 300% More Pre-Workout Calorie Burn to Ramp Up Your Energy Production*

What is Amplified Muscle Igniter 4X?
If amplifying training performance is what you want, Amplified Muscle Igniter 4X is what you need. GNC's first and only 4-phase supplement with clinically researched blends designed to encompass the multiple aspects of workouts - delivering benefits before, during and after exercise. This multi-phasic formula supplies clinically proven components to support the metabolic phases of muscle action throughout training. Its 4-phase system supports cellular reactions that help enhance pre-workout calorie-burning, improve physical and mental intensity, ignite heat shock proteins (HSPs), increase endurance and support the recovery process - all in one dynamic formula!* Amplified Muscle Igniter 4X - GNC's first and only 4-phase thermogenic workout enhancer.

The Amplified Muscle Igniter 4X Evolution
Amplified Muscle Igniter 4X is a supplement that provides the complete formula to take you through the full metabolic cycle of athletic performance and training.*

Calorie Burn Blend - Burn more calories before, during, and after workouts. This exclusive Calorie Burn Blend features technology-enhanced red and black pepper extracts and other superior components proven to provide calorie-burning effects.* Now with White Willow, a natural source of Salicin, Salicin may impact enzymatic pathways in the body that can potentiate caffeine's thermogenic response.

Performance Blend - Workout harder and longer. The proprietary Performance Blend features naturally caffeinated plant extracts and other natural ingredients proven to improve endurance and workout intensity.*

Sports Antioxidant Blend - Now with clinically studied ResVida® Resveratrol, shown to enhance blood vessel dilation*. Good blood flow helps pump more oxygen and nutrient-rich blood through the body to fuel your workout! Plus includes Fenugreek and Yohimbe for natural herbal pump and Quercetin, a powerful antioxidant.

400 mg of Caffeine - With the amount of caffeine infused into this formula, you will be sure to feel the difference in the level of energy exerted during each workout. This caffeine load helps to promote the heat shock element and provides a signaling pathway, which results in HSP activation*. This HSP Activator is involved in releasing heat shock proteins during exercise.* HSPs are proteins induced by heat or other stresses that play a role in muscle physiology and are multi-functional.

Who Should Take Amplified Muscle Igniter 4X?
Amplified Muscle Igniter 4X is designed for athletes who desire to burn more calories, improve physical and mental intensity, and enhance energy and cardio endurance capacity.*

When Should I Take It?
Amplified Muscle Igniter 4X should be taken 30 to 60 minutes pre-workout. On non-training days, the product should be taken first thing in the morning with water.

The 4-Phase System for Undeniable Results!
PHASE 1: Pre-Workout Calorie Burn

300% More Pre-Workout Calorie Burn to Ignite Your Metabolism!*
Amplified Muscle Igniter 4X has thermogenic properties proven to help you burn more calories.*
*In a study, a group of 24 participants exercised on the treadmill on two occasions. On one occasion, they used the Calorie Burn Blend in this formula 60 minutes before exercise and on the second occasion, they took a placebo.

Health Notes

Conjugated Linoleic Acid

Conjugated Linoleic Acid
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:

Obesity
Dose: 3.2 to 4.2 grams daily
Though the evidence is conflicting, some studies have shown CLA to be effective at helping people lose body fat. (more)
Athletic Performance
Dose: Refer to label instructions
Conjugated linoleic acid may play a role in reducing body fat. Research has reported that CLA supplementation produces minor gains in muscle size and strength in weight-training men.(more)
Prostate Cancer
Dose: Refer to label instructions
Preliminary research suggests that CLA might reduce the risk of cancers at several sites, including breast, prostate, colorectal, lung, skin, and stomach.(more)
Breast Cancer
Dose: Refer to label instructions
Preliminary research suggests that CLA might reduce breast cancer risk.(more)
Obesity
Dose: 3.2 to 4.2 grams dailyA double-blind trial found that exercising individuals taking 1,800 mg per day of conjugated linoleic acid (CLA) lost more body fat after 12 weeks than did a similar group taking a placebo.1 However, two other studies found that amounts of CLA from 0.7 to 3.0 grams per day did not affect body composition.2, 3 Most double-blind trials have found that larger amounts of CLA, 3.2 to 4.2 grams per day, do reduce body fat;4, 5, 6, 7 however, one double-blind study of experienced strength-training athletes reported no effect of 6 grams per day of CLA on body fat, muscle mass, or strength improvement.8

Athletic Performance
Dose: Refer to label instructions

Conjugated linoleic acid (CLA) is a slightly altered form of the essential fatty acid linoleic acid. Animal research suggests an effect of CLA supplementation on reducing body fat.1, 2 Controlled human research has reported that 5.6 to 7.2 grams per day of CLA produces only non-significant gains in muscle size and strength in experienced and inexperienced weight-training men.3, 4, 5 A double-blind study of a group of trained men and women reported reduced body fat in the upper arm after 12 weeks of supplementation with 1.8 grams per day of CLA.6 Further research using more accurate techniques for measuring body composition is needed to confirm these findings.

        Comments about GNC Pro Performance® AMP Amplified Muscle Igniter 4X:

        This is a good product. Works very well for me I take one in morning about 15-20 min before workout. Keeps me pumped during my hour workout.

        A few things to consider. I started taking 2 before workout it was defintily a bigger bang, but I like to drink coffe once i go to work. This must over stimulate u. I crash hard about 1-2 pm. They say don't drink coffee with this product. I still do but not after taking 2. Unless I can take a afternoon nap.

        Over all a lot cheaper than energy drinks for about the same bang.

                WOW!!! I STARTED TAKING THESE ABOUT A WEEK AGO, BUT ONLY 1 PILL MIXED IN MY 72 OZ BREAKFAST SHAKE. IT GAVE BE A NICE LITTLE BOOST. YOUR SUPPOSED TO TAKE 3. SO TODAY, I DID. I STACKED THEM WITH HIGH T BLACK TESTOSTERONE BOOSTER, AND IN 5-10 MIN I WAS READY TO TAKE OFF SPRINTING, NOT JOGGING. I HATE SPRINTING, SO THE MERE FACT THAT WAS HAPPENING, BLEW ME AWAY. I HAVEN'T TRIED AMP 4X WITHOUT THE HIGH T, SO I CAN'T SAY HOW THAT WOULD BE LIKE. BUT MAKE KNOW MISTAKE IF YOU TAKE IT HOW I DID, MAKE SURE YOUR GOING TO THE GYM OR AT LEAST TO RUN, BECAUSE IF YOU DON'T YOUR GOING TO BE PACING AROUND THE HOUSE AT A CRAZY PACE, FOCUSING ON ALL KINDS OF DIFFERENT THINGS. SO USE IT WISELY. I HAVE NOT TRIED ANYTHING ELSE BEFORE, SO I CAN NOT COMPARE IT TO A DIFFERENT BRAND, BUT IF SOMEONE RECOMMENDS THIS PRODUCT TO YOU, YOU WILL NOT BE DISAPPOINTED!!! IT'S A MUST TRY!!! IF NOTHING ELSE?!!! I LOVE THIS STUFF!!! BY THE WAY, I'M NOT A SMALL GUY. I'M 260 LBS, SO IF IT DOES THAT TO ME, IMAGINE WHAT BOOST IT GIVE SOMEONE OF A SMALLER FRAME. I'D GIVE IT, AND HIGH T TOGETHER A 6 OUT OF 5 IF I COULD.
                RECOMMENDATION: TRY IT NOW!!!
