More Key Aminos — In addition to a whopping 7.7 grams of leucine, this formula is loaded with an array of aminos necessary for your muscles. This complex blend of amino acids delivers 3.6 grams of arginine, which is involved in creating 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.*

Additional Information

*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.

Per 3 scoop serving.

Store in a cool, dry place.

It is GNC's top protein formula 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.^* That's better fuel for a stronger body — premium protein for ADVANCED MUSCLE PERFORMANCE.*

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 thr untrained limb demonstrated increases in muscle size.*

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... 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 hydrosalates. 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.*

{chart} ^1 SET + AMPLIFIED WHEYBOLIC EXTREME 60(TM) ORIGINAL = 2 SETS! SUPPLEMENT + 1 SET 2 SETS WITHOUT SUPPLEMENT In an 8-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.
