鈥淥ur customers are doing the hard work in the gym and in the kitchen, but they鈥檙e also asking a smarter question: 鈥業s my protein actually helping me get stronger?鈥欌�� said . 鈥淭he new GNC AMP Wheybolic was built to answer that with a resounding YES. It combines a high level of total protein, additional leucine, rigorous clinical backing and third-party testing 鈥� all at the same price many people already pay for a basic protein. If you train with purpose, this is the protein that takes your effort and makes sure it shows up in your strength and endurance."

Leucine: the key amino acid that turns protein into progress
Most people look at grams of protein on the label. GNC鈥檚 science team has taken it a step further and also focused on the amino acid . In fact, GNC has conducted several studies on blends of whey protein with added leucine鈥攅ach of which showed benefits for things like strength, recovery, muscular endurance, exercise efficiency, etc.

GNC has long believed in the power of leucine, as leucine is one of the three branched-chain amino acids and plays a central role in activating muscle protein synthesis 鈥� the process that helps muscles repair and grow after training. The new GNC AMP Wheybolic delivers 6.2 grams of total leucine per serving, matching the level used in GNC鈥檚 latest .

Each serving of the new formula provides:

• 50 g total protein (from ultra-filtered whey isolate and whey protein)
• 6.2 g total leucine to help trigger muscle protein synthesis
• Fast-digesting whey to support post-workout recovery

"Not all protein scoops are created equal," said . "From a muscle perspective, leucine is one of the key signals that tells your body to start building and repairing. With our most recent study, we showed that the protein and leucine combo in GNC AMP Wheybolic helped 100% of the people in the once-daily treatment group to get stronger鈥攈ow great is that?"

The new GNC AMP Wheybolic is backed by clinical research conducted by the GNC Science & Innovation team. In an 8-week randomized controlled trial, a once-daily serving of a leucine-rich whey protein blend combined with progressive resistance training produced  compared to placebo.

These independent, third-party certifications help ensure that:

• Every batch is tested for banned substances, supporting athletes in drug-tested sports
• Protein content is independently verified, helping confirm that each scoop delivers the protein listed on the label
• GNC AMP Wheybolic is formulated without amino acid "spiking" practices that can artificially inflate protein numbers

鈥淐ustomers are rightly skeptical about big claims in the protein category,鈥� added Jones. 鈥淲ith GNC AMP Wheybolic, we鈥檙e giving them more than a label promise. We have clinical data, we have third-party certifications for protein accuracy and sport safety, and we have a science team that lives and breathes this work every day.鈥�
