🧪 Formulation Notes

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.

Powered with 10 grams Glutamine & 4 grams Arginine

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.*

Contains: Milk and Soybeans.

Now GNC has made their 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 it's 100% improvement in exercise efficiency, we have AMPed up the protein with a total of 10 grams of leucine for protein synethesis and doubled the hydrolysates for rapid absorbing critical protein. That's better fuel for a stronger body - premium protein for ADVANCED MUSCLE PERFORMANCE.*

More 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.

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

Premier whey + leucine formula

Now with 10 grams of Leucine & more fast-acting Whey Hydrolysates

Additional Information

30% Increase in Muscle Strength

The athletes using this proprietary module of whey protein and leucine demonstrated an increase 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 increase in muscle size.

Inclusion of the 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 stimulated conditions. Effects in the human body have not been studied.

-Proven 30% increase in muscle strength -Increase strength & stamina with half the sets -Supports muscle recovery & growth

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...

Why is that important? Better absorption of amino acids means better muscle fuel. These key amino acids support muscle building and recovery.* 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.

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

{Chart} ^1 SET = AMPLIFIED WHEYBOLIC EXTREME 60(TM) = 2 SETS SUPPLEMENT + 1 SET 2 SETS WITHOUT SUPPLEMENT

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.

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

Per 3 scoop serving.
