Scivation Xtend (90 Servings)
Creatine is used in the high-energy phosphate or ATP-PCr system to regenerate ATP. ATP, the body's main source of energy, is a molecule of adenosine (adenine + the sugar ribose) linked to three phosphate molecules by high-energy bonds. Breaking of the two outer bonds results in the release of energy.
When the most outer bond is broken, the energy is released and ADP and Pi are left behind. Creatine, which is bonded to a phosphate ion, transfers energy to the ADP and Pi molecule by breaking its own bond. This regenerates the ATP molecule, which means one now has more energy to use.
Skeletal muscle has a limited storage of creatine. Therefore supplementing with creatine increases your ability to form ATP and therefore increases the available energy for exercise (Casey et al. 1996 & 2000). More importantly to our topic on hand, by keeping ATP levels by supplementing with creatine we increase protein synthesis through mTOR activation. Creatine also has many other beneficial effects that are too numerous to address here.

Nitric Oxide (NO) product (Arginine, DiArginine-Malate, AAKG, etc)
- The rate-limiting step of amino acid uptake into skeletal muscle is the transportation of the amino acids through the blood to the skeletal muscle, which is governed by blood flow (Wolfe, 2004). NO vasodilates blood vessels, thereby increasing blood flow. This increase, when combined with exercise, means greater blood flow and greater amino acid deliver and uptake in the working skeletal muscle. Exercise itself results in an increase in NO production, and the increased blood flow created by exercise is believed to be linked to the increase in protein synthesis post workout (Douglas et al., 2004). Xtend already has Citrulline-Malate in it, which will increase NO production, but an additional serving of arginine (i.e. 5 grams) preworkout should further enhance NO production, blood flow, and amino acid uptake.

excellent

It is the best and the most quickly absorsbed amino I have ever tried.
I have tried last time taste orange, it was good, but this time blue rasberry was better!
