USN L-Glutamine Powder 625g

A pure, free form anti-catabolic amino acid. A multi-functional amino acid, used to increase muscle strength, speed up recovery, prevent muscle breakdown & increase natural hGH

L-Glutamine is an amino acid. During intense training, your muscle L-Glutamine levels drop sharply. This, in turn decreases strength, stamina and recovery. Research demonstrates that following a rigorous workout, it may take up to six days for L-Glutamine levels to return to normal without supplementation. Without adequate levels of L-Glutamine, it is impossible for protein synthesis to occur.

L-Glutamine also increases cell volumization immediately. Volumized muscle cells appear larger, get a better pump and assist in protein synthesis. In fact, L-Glutamine helps muscle cells to utilize both protein and carbohydrates. L-Glutamine also acts as a powerful ammonia scavenger. Ammonia is a highly toxic substance to muscle cells.

Finally, L-Glutamine increases the body's ability to secrete Human Growth Hormone (HGH). HGH assists in metabolising body fat and helps to support new muscle tissue growth. Research demonstrates that the muscles can benefit from a minium of 2 to 5 additional grams of L-Glutamine daily.

There are no negative side effects to L-Glutamine use.


•Prevents muscle breakdown.
