🧪 Formulation Notes

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.

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) Strength 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) Strength? Those who are participating in resistance training regimens seeking improvements in muscle strength, size and stamina.

Nitro-Factor(TM) - Maximize Muscle Building The full muscle-building potential of a GNC product is based on its total nitrogen content - so the more nitrogen a product has, the stronger it will perform. Pro Performance(R) AMP Amplified Wheybolic Extreme 60(TM) Strength with a Nitro-Factor(TM) of 72 grams helps fuel performance and anabolism.

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

- 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

NATURAL + ARTIFICIAL FLAVORS

CONTAINS: Milk and Soybeans.

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.

REGULATE INSULIN T0 MAXIMIZE YOUR ANABOLIC WINDOW 10G WHEY PROTEIN ISOLATE 10G LEUCINE INCREASES INSULIN BY 400% FOR IMPROVED MUSCLE BUILDING AND RECOVERY

In a randomized, double-blind, cross-over clinical trial that included 20 recreationally trained, healthy male subjects, those taking this WPI and leucine blend immediately post-workout showed significant increases in plasma insulin concentration. Those taking the WPI and leucine blend showed 400% more insulin 30 minutes post-workout compared to a placebo.

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.

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.

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