**As with any food product, use of this product alone will not lead to increased muscle mass or strength. This product is, however, useful for athletes involved in regular intense resistance training programs.

Amino Acceleration System

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.

An 8-week study of athletes performing an intense resistance exercise training regimen demonstrated that those using this proprietary module of whey protein and leucine had greater increases in muscle strength and size than those on a placebo.**

CARB PLACEBO GROUP

Clinically Researched

CODE 351143 KJG

Daily Strength Recovery Stamina

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.

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 hydrolysates. With 7.7 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.

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…

In an eight week randomized double-blind placebo-controlled study of 30 healthy male volunteers comparing 1 set resistance training (RT) + active or carbohydrate placebo to 2 sets RT alone with no supplement, the active group showed equal gains in maximal muscle strength (MMS) and muscle endurance (ME) compared to the control group.

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.

Premier whey + leucine formula

Rapid Absorbing Whey Isolates & Hydrolysates

SUPPLEMENT + 1 SET

The Proof is in the Protein – and then some…

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. 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.**

This cutting-edge formula is scientifically engineered to AMPlify your game.

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