Max Muscle Sports Nutrition (MMSN) is proud to introduce XTR.
A scientifically-based formula to provide the body with high potency
branched-chain amino acids in the ideal 2:1:1 ratio of Leucine,
Isoleucine, and Valine. As a duel action formula, XTR is specifically
designed to benefit both pre- and post-workouts. For the pre-workout,
this comprehensive formula is designed to support the energy
fuels needed for high intensity and endurance workouts. For the
post-workout, it functions to support rapid recovery, muscle anabolism
and anti-catabolic effects.
BCAAs (L-Leucine, L-Valine and L-Isoleucine) are known to be
highly concentrated in muscles (35%) and have been shown to serve
as important fuel sources for skeletal muscles during periods of
high-intensity exercise. The BCAAs improve protein & nitrogen
balance in muscle, preserve muscle glycogen reserves, suppress
protein catabolism, and overall have an anti-catabolic effect.
Additionally, the BCAAs stimulate the production of the amino acids alanine
and glutamine.
L-Citrulline-Malate promotes aerobic energy production, serves
to remove lactate and ammonia from muscle cells, reduces muscle
fatigue and supports arginine synthesis and superior for nitric oxide
(NO) production.
L-Glutamine (Gln) is a “conditionally essential” amino acid and is the
most abundant amino acid in muscles (60%). Gln is often depleted
during exercise, overtraining and stress. Athletes may not produce
enough Gln to support muscle requirements during recovery. Gln
supports intestinal enterocytes and preferentially used by cells of the
immune system. Gln is a “workhorse” amino acid to prevent protein
catabolism (breakdown) and is anti-catabolic.
L-Glycine supports natural GH and adds to the sweet flavor of XTR.
Arginine Alpha-Ketoglutarate (A-AKG) is made up of two molecules of
arginine attached to one molecule of alpha-ketoglutarate. It is believed that
this molecular form of arginine enhances the absorption of arginine. Arginine
Alpha-Ketoglutarate enhances the production of nitric oxide.
Alpha-ketoglutarate (AKG) is a key biochemical intermediate in the Citric Acid
Cycle (central point for energy production located in muscle mitochondria) and
links or is a gateway of the Citric Acid Cycle to amino acid (protein) synthesis.
Alpha-ketoglutarate is also the metabolic precursor to synthesize cellular glutamine.
AKG has been used to improve athletic performance.
Vitamins C, B6, B12 and Biotin are metabolic cofactors for enhanced
biochemical utilization of the BCAAs.
XTR is designed to be used as a pre-workout, anti-catabolic, post-recovery formula.
To be used during strength or endurance exercise to decrease the catabolic activity
of muscles.
