SciVation Xtend + Shaker

Scientifically Advanced Endurance and Recovery Support Formula

Xtend is a precise, scientific blend of Energy Aminos consisting of the surmised 2:1:1 ratio of Branched Chain Amino Acids (L-Leucine, L-Isoleucine and L-Valine), Glutamine, Citrulline Malate, and Vitamin B6 that will give you the energy you need to maximize your training while promoting recovery at the same time.

The advanced components in Xtend have been scientifically suggested to help speed recovery and enhance ATP production and promote cell volumization.

  • Avoid fatigue by blocking entry of fatigue-inducing tryptophan into the brain.
  • Support protein synthesis, immune function and digestive health.
  • Promote vasodilation which can lead to better assimilation and absorption of protein.
  • Elevate growth hormone levels.

If I already eat a lot of protein, will additional free-form BCAA be beneficial to me?
The metabolic effects seen from ingesting free-form amino acids are different from ingesting the same amino acids when they are in a whole protein (peptide bond). The rapid flushing of the system with the particular amino acid exerts a much more powerful activation of its target pathways. For example, if you were to ingest 5 grams of free-form arginine pre-workout you may notice a greater pump then without it.* If you were to ingest 5 grams of arginine in the form of a whole protein (1) you'd have to eat a ton of protein to acquire the 5 grams of arginine and (2) the rate of delivery would be much slower and (3) you would not be flooding your system with a large dose of arginine at one time. The same holds true for BCAA. Ingesting 10 grams of BCAA will lead to greater activation of mTOR, PI3K, etc. than ingesting 10 grams of BCAA from a whole protein.

What if I already take in a lot of whey protein which is high in BCAA?

Free-form amino acids are absorbed quicker than whey, and as stated above, whey will not flood your bloodstream with BCAA as quick as ingesting free-form BCAA. The BCAA from whey compared to free-form BCAA could be compared to filling up a glass of water from a garden hose (whey) to a faucet (free-form BCAA). If you use a garden hose you have to wait until the water travels the length of the hose before you can use it. With a faucet, the water is right there when you turn it on. On top of this, the faucet has a wider opening than the garden hose and releases more water than the garden hose. During your workout and times of stress (dieting), you want the BCAA to get to your muscles as quickly as possible.

Can women take Xtend?
Yes. Xtend is very effective for both men and women.
