🧪 Formulation Notes

- Proven 30% Increase in Muscle Strength + 60g Whey Isolate to Support Recovery & Muscle Growth - 10g Leucine, 10g Glutamine, 4g Arginine & Fast-Acting Whey Hydrolysates to Accelerate Performance

CONTAINS: Milk and Soybeans.

This product is, however, useful for athletes involved in regular intense resistance training programs.

Now GNC has made thier top protein formula even more intense! Along with a base of whey and leucine - proven in clinical studies to give you 30% increase in strength, increased muscle size, and a 100% improvement in exercise efficiency - we have AMPed up the protein with a total of 10 grams of leucine for protein synthesis and doubled the hydrolysates for rapid absorbing critical protein. That's even better fuel for a stronger body - premium protein for ADVANCED MUSCLE PERFORMANCE.

Highly Effective Whey-Leucine Base - The impressive 60 grams of protein is made entirely from two of the highest quality, fast-absorbing forms of whey protein - isolates and now even more hydrolysates. With 10 grams of leucine, this creates an ideal environment for muscle protein synthesis. This potent blend upregulates multiple Genetic Signaling Pathways (GSP) to enhance anabolism and muscle performance. In fact, the whey and leucine blend in Amplified Wheybolic Extreme 60(TM) has been shown to increase muscle strength and stamina with half the sets.

Amino Acceleration System - This digestive enzyme blend is designed to accelerate the availability and absorption of amino acids to be efficiently used by the muscles.

Moro Key Aminos - In addition to a whopping 10 grams of leucine, this formula is loaded with an array of aminos necessary for your muscles, which are delivered through advanced technologies that help to create a dual flow of quick-absorbing aminos through a blend of micronized and non-micronized amino acids that act as critical fuel for protein synthesis and nitrogen balance. This complex blend of amino acids delivers 4 grams of arginine, which is involved in creatine synthesis, and over 10 grams of glutamine providing anabolic effects. The amino acid L-carnitine is included to help transform fatty acids into energy for muscles and the body’s energy production system.

Amino Acceleration System Features an Amino Acceleration System - a digestive enzyme blend with proven bioactivity. This proprietary enzyme blend provides a 12% greater protein breakdown for improved amino acid uptake.

Who can benefit from taking Amplified Wheybolic Extreme 60(TM)? Those who are participating in resistance training regimens seeking improvements in muscle strength, size and stamina.

30% Increase in Muscle Strength The unique protein blend includes an anabolic module of 20 grams of whey protein and 6.2 grams of leucine that was clinically tested in an 8-week study of athletes performing an intense resistance exercise training regimen.

Significant product settling may occur.

As with any food product, use of this product alone will not lead to increased muscle mass or strength.

Inclusion of these enzymes resulted in a 12% greater protein breakdown as measured by the release profile of the amino acid tyrosine. These results represent the enzyme activity potential under simulated conditions. Effects in the human body have not been studied.

How is this protein AMPlified? GNC's scientists worked with leading exercise and sports nutrition experts and went beyond the extreme to develop this distinct product...

The Proof is in the Protein - and then some... This cutting-edge formula is scientifically engineered to AMPlify your game.

The athletes using this proprietary module of whey protein and leucine demonstrated an increased improvement in muscle strength and muscle size as compared to those performing the same exercise training regimen who did not consume the proprietary module. In a clinical study of participants using a unilateral lower limb resistance training protocol, even the untrained limb demonstrated increases in muscle size.
