"Supplemental Leucine allows for the muscle to achieve maximum protein synthesis and anabolic recovery."

Increase the anabolic effectiveness of your protein powder or protein meal with the use of Leucine Peptides, much more effective than L-Leucine!

Increasing your dietary protein intake is the key to growing muscle. Specifically using high quality protein such as whey protein contains an extraordinarily high amount of BCAA’s (over 30%). BCAA’s are known as the building blocks of muscle. BCAA’are made up of Leucine, Valine, and Isoleucine. Recently it has become known that taking 5 grams of Leucine with a protein shake or protein meal will increase protein synthesis by up to 70%. But the problem is that one can only buy L-Leucine, which is a single amino acid. This creates problems in the digestive tract as the body has trouble digesting single free form amino acids. Therefore, supplement company’s and research groups that recommend supplementing with L-Leucine in hopes to increasing protein synthesis, instruct to take L-Leucine with food (other amino acids). But still this may not be enough for the body to digest and absorb the L-Leucine supplement. To solve this problem, ProteinFactory.com is now offering Leucine Peptides. Leucine Bound Leucine Peptides (LBLP) are made from a proprietary process that binds free form Leucine to Leucine peptides isolated from whey protein using advanced fractionation and separation technologies. Leucine Peptides are much more absorbable and digestible than L-Leucine. Leucine Peptides are in the form of di and tri peptides, or two or three amino acids linked together. The body absorbs amino acids through the intestinal tract and into the blood stream in the form of di and tri peptides. Therefore net protein utilization and synthesis is increased more dramatically using Leucine peptides over L-Leucine. Our Leucine Peptides are made in the USA from the finest quality whey protein isolate and contains a complete amino acid profile including BCAA’s.

Serving size (1 tsp) 5 grams
Servings per pound: 90

If taken 3 times per day 1 pound will last 30 days.

Instructions: Mix 1 tsp of Leunox with your protein shake or sprinkle on any protein meal. Do not exceed 4 times per day. Best time to use Leunox is post workout with a hydrolyzed protein like (PeptoPro, or Hydrolyzed 1400) and a Carbohydrate. For beginners or those concerned with taste, use Leunox with one of our Whey Protein Isolates, like Native Whey Isolate or Ultra Amino 97 Whey Isolate

Leucine Regulates Translation Initiation of Protein Synthesis in Skeletal Muscle after Exercise

ABSTRACT
High-performance physical activity and postexercise recovery lead to significant changes in amino acid and protein metabolism in skeletal muscle. Central to these changes is an increase in the metabolism of the BCAA leucine. During exercise, muscle protein synthesis decreases together with a net increase in protein degradation and stimulation of BCAA oxidation. The decrease in protein synthesis is associated with inhibition of translation initiation factors 4E and 4G and ribosomal protein S6 under regulatory controls of intracellular insulin signaling and leucine concentrations. BCAA oxidation increases through activation of the branched-chain α-keto acid dehydrogenase (BCKDH). BCKDH activity increases with exercise, reducing plasma and intracellular leucine concentrations. After exercise, recovery of muscle protein synthesis requires dietary protein or BCAA to increase tissue levels of leucine in order to release the inhibition of the initiation factor 4 complex through activation of the protein kinase mammalian target of rapamycin (mTOR). Leucine's effect on mTOR is synergistic with insulin via the phosphoinositol 3-kinase signaling pathway. Together, insulin and leucine allow skeletal muscle to coordinate protein synthesis with physiological state and dietary intake.
