Additional Information

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. 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.

STACK WITH: PRO PERFORMANCE(R) AMP Amplified Strength, Amplified Push and Amplified Recover PM.

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

Per 3 scoop serving.

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.

30% INCREASE IN MUSCLE STRENGTH COMPARED TO PLACEBO {graph} 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 and strength and size than those on a placebo.

This product is the only whey protein isolate to combine the whey and leucine clinically shown to fuel increased strength and size with additional ingredients proven to amplify power and anabolism. This formula features a protein blend that has been validated in clinical studies to give you a 30% increase in strength, increased muscle size and a 100% improvement in exercise efficiency. Our GNC scientists have AMPed up the protein with a Power Complex featuring an mTOR-stimulating BCAA blend for protein synthesis and added creatine to increase anabolic muscle growth, making this product a combination of 7 products in 1!

This breakthrough formula takes protein functionality and performance to new levels so you can break through plateaus and achieve a new level of muscular power.

Power Complex In addition to 10 grams of leucine this formula is stacked with 4 grams of both isoleucine and valine to stimulate mTOR activation and give you a powerful boost of all three BCAA to fuel your workouts and enhance your recovery. This product has upped the ante and added a 3 gram creatine blend to boost anabolic factors in the body, increase athletic performance and fuel strength + 600mg of Testofen(R) Fenugreek to help support testosterone levels in the body.

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, including 10 grams of leucine to create an ideal environment for muscle protein synthesis. This potent blend delivers Arginine, which is involved in creatine synthesis, and over 10 grams of glutamine to provide anabolic effects. In fact, the whey and leucine blend in this product has been shown to increase muscle strength and stamina with half the sets.

Powerful Amino Acid System This product is loaded with arginine and glutamine, two key amino acids necessary for muscle, building and recovery. Over 10 grams of glutamine helps to combat catabolism and support muscle function, while arginine helps to support blood vessel tone and blood flow, and is involved in the production of creatine.

Digestive Enzyme Blend for 12% Greater Protein Breakdown This digestive enzyme blend with proven bioactivity is designed to accelerate the availability and absorption of amino acids in muscles. This proprietary enzyme blend provides a 12% greater protein breakdown for improved uptake.

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. Nitrogen needs increase during training, and if nitrogen levels are low, your body pulls from muscle stores which can result in catabolism, poor performance and longer recovery.

Whether you're a serious athlete, weekend warrior or training for a competition, you can benefit from this powerful formula. Now you can customize your dosing to meet your specific training goals and nutrient needs. Boost power and anabolism while improving muscle strength, stamina, size and recovery!
