🧪 Formulation Notes

The HARDCORE MUSCLE FEEDER is loaded with 500 mg D-Aspartic Acid plus Anabolic Primers that work to maximize muscle protein synthesis. Leucine, from a rapid-absorbing whey protein source, works to turn on mTHOR, the anabolic signaling pathway for muscle protein synthesis while tuning out catabolic signals that interfere with muscle growth.Together with other key ingredients, these potent amino acids stimulate the powerful Anabolic Hormone insulin needed for Carbohydrate Metabolism and immediate Muscle Cell Energy for a staggering 400% improvement in the anabolic environment. Plus, this dynamic formula contains powerful minerals to help maintain Water Regulation, and neurotransmitter building blocks, phenylalanine and tyrosine, to support Neuro Priming.

CONTAINS: Milk and Soybeans.

When stacked with a product containing whey protein isolate (WPI) in a randomized, double-blind, cross-over clinical trial that included 20 recreationally trained, healthy male subjects, those taking 10 grams WPI and 10 grams leucine immediately post-workout showed significant increases in plasma insulin concentration. Those taking the WPI and leucine blend showed 4 times more insulin 30 minutes post-workout compared to a placebo.

In a randomized, double-blind, cross-over study of 16 healthy male volunteers, subjects experienced significantly higher maximum concentrations of Total Amino Acids, Branched Amino Acids and Leaucine 1 hour post-ingestion of the protein blend in this product relative to amino acid concentrations measured post-ingestion of whey protein concentrate. Significant differences for the Rate of Change of BCAA and Leucine absorption were also observed relative to the control group.

Store in a cool, dry place.

In an 8-week study of healthy males performing resistance training, subjects taking this product's module of 20g whey protein and 6.2g leaucine demonstrated an increased improvement in muscle strength and muscle size as compared to those performing the same training regimen on a placebo.
