Amino Acids

The chemical building blocks of proteins are essential to the human body and all its processes. There are twenty-one in all and most are termed non-essential because they are produced by the body itself. Bodybuilders, however, deplete bloodstream levels of certain non-essential aminos (glutamine, for instance) swiftly, requiring supplemental intake. Other amino acids (the BCAAs valine, leucine, and isoleucine) can only be acquired through dietary intake, and are thus termed essential. Different aminos are linked to different processes, some of which are of special interest to bodybuilders. Arginine has been linked to vasodilation and nutrient delivery; tyrosine to focus and intensity; glutamine to muscle recovery after exercise. To achieve your bodybuilding goals, you need to know your aminos.

    ProSourceGlutamine PowderAnti-Catabolic Super Nutrient   Premium Grade Bodybuilding Staple Helps Prevent Muscle Breakdown Enhances Protein Synthesis 100% Pure Free-Form L-Glutamine 120 Servings Per Container Glutamine is the most abundant free amino acid in muscle tissue, which means that pure, free-form L-glutamine, taken before and after intense exercise serves the bodybuilder like few other supplements. This difference-making amino works by helping to combat muscle breakdown, helping to increase protein synthesis and nitrogen retention, enhancing cell volumization and supporting an overall potent anti-catabolic response.That's why supplementation with ProSource's free-form L-Glutamine is an indispensable component of the serious athlete's bodybuilding regimen.
Recent research also reveals that glutamine's value goes beyond enhanced muscle recovery and repair. In fact, one landmark study has reported that L-glutamine supplementation can increase body weight, body cell mass, and intracellular water in a manner not unlike Creatine monohydrate. Finally, clinical research suggests that glutamine is essential for maintaining intestinal function, immune response, and amino acid homeostasis during periods of severe stress (such as intense exercise).Few compounds in your arsenal do more for you than this extraordinary super nutrient. Keep your hard-earned mass gains—put the brakes on catabolism and find out why it’s called bodybuilding’s most important amino acid with 100% pure, free form L-Glutamine from ProSource. Just one teaspoon (5 grams) per serving provides the essential benefits every bodybuilder needs to grow at maximum capacity.(Each batch of ProSource L-Glutamine is tested and certified to be 100% pure by an independent analytical laboratory using the HPLC (high pressure liquid chromatography) method of analysis.)

    PROSOURCE L-ARGININE L-Arginine is one of the most popular bodybuilding amino acids for good reason. Copious amounts of research have shown that it has a potent vasodilation effect, which brings more nutrients to muscle tissue. It’s also been linked to enhanced muscle synthesis, proper immune system function and potential cardiovascular support. Although L-arginine is available in many food sources, its many benefits add to its important use in supplement form. Trust ProSource for the highest quality aminos on the market. Use as directed with a sensible nutrition and exercise program. Read and follow all product label instructions and warnings thoroughly before use.

    ProSource Mega BCAA CapsAnti-Catabolic and Energy Support Aminos   Premium Quality Ingredients in Precise Ratio Spares Muscle During High Intensity Workouts Helps Maintain Nitrogen Balance Bodybuilding Staple Most bodybuilders know that BCAAs (composed of the aminos leucine, isoleucine and valine) are the indispensable building blocks for the growth and maintenance of a lean, muscular physique. What many do not know, however, is that the quality of BCAA supplements can vary wildly from product line to product line. Now, you can buy these key anti-catabolic, muscle-sparing branched-chain amino acids with confidence when you choose the ProSource brand. Other manufacturers simply lack the ProSource direct-to-the-consumer cost advantage, and are forced to settle for inferior source material. And when quality suffers, so do results.Fortunately, both Mega BCAA Capsules and Powder contain a precise ratio (2:1:1) of vastly superior, premium-grade aminos, leucine, isoleucine and valine. Of the three, leucine is especially critical to the mass building equation, primarily because of its significant role in protein synthesis. More and more evidence points to leucine as a potent, muscle-sparing, anabolic support nutrient. In the form of BCAAs, leucine is most effective when taken with the other two aminos. For example, isoleucine is needed to help support energy levels, and valine is necessary for muscle metabolism support, tissue repair and proper maintenance of nitrogen balance. Synergistically, these powerfully anti-catabolic amino acids work together to help energize, protect and build muscle tissue.For a crucial supplement like BCAAs, you need the best quality you can find. Like all ProSource sports supplements, Mega BCAA Powder and Capsules are made with the absolute highest quality ingredients available industry-wide to ensure maximum purity, potency and results!Read Super Feature Article: Amino Acids: Your Best Choice For Optimum Health, Growth, Energy And Focus Branched-Chain Amino Acids: A Blast From The Supplement Past Bcaas: Essential Building Blocks Of Muscle Growth  Click to read about An inside look at the ProSource headquarters: See What Sets Our Brand Apart   Use as directed with a sensible nutrition and exercise program.

    PROSOURCE SUPER AKG Several years ago the bodybuilding world was rocked by the introduction of Arginine AKG and its potent nitric oxide (N.O.) inducing capabilities. It literally changed the supplement protocols for innumerable athletes. At the onset, it was available in very few supplement brands. One of those was ProSource. The only difference between ProSource’s Super AKG and those other brands, was the price. ProSource Super AKG was created specifically to provide those colossal pumps...at a much more reasonable price. Super AKG is scientifically formulated using superior premium-grade Arginine AKG and is designed to pump out maximum nitric oxide production.
 Arginine AKG is a combination of the amino acid arginine and an alpha-ketogluterate molecule. Each provides separate benefits, but together, working synergistically, it makes for a potent N.O. producing, growth enhancing powerhouse.This mass-building, pump-producing dynamo is highly reactive and plays a critical role in increased blood flow by a process called vasodilation, for improved nutrient delivery, amplified growth signals, muscle recovery and increased endurance. In fact, in a standard Time to Disintegration test, Super AKG reached full disintegration in 180 minutes, which is identical to what the leading nitric oxide product.
Utilizing a unique extended release delivery system, Super AKG is able to sustain levels of nitric oxide production in the muscle cells for extended periods throughout the day. As a result, users are reporting greater strength gains, recovery and increased endurance.

 The other great advantage to choosing Super AKG is that you get all the pump and mass producing benefits at a lower price than other brands. The amazing Super AKG represents the ultimate product of its kind in this powerful mass-building category. One try and you'll see why it's the only NO product you should use.

    ProSourceMyo-SurgeThe Original Pre-Workout Powerhouse Massive 9.75 Gram Dose of Essential Aminos Glutamine for Muscle Recovery Additional L-Tyrosine for Focus Support Most athletes recognize the importance of supplementing with a top-quality post-workout like MyoZene or After Mass following exercise. Many do not know, however, that fueling up on essential BCAAs and glutamine before working out could be as important to the mass-building equation. This fact is supported in at least one key study indicating that pre-workout supplementation may be equal to post-workout supplementation when it comes to enhancing protein synthesis. It’s research like this that helped impel the ProSource product development team to create this simple, yet rock-solid formula in order to give bodybuilders that instrumental nutrition for maximum muscle support before and during an intense workout.If you're not getting the mass-building results you want from your workout regimen, Myo-Surge pre-workout formula may be the solution. 

Myo-Surge gives your glutamine levels a powerful boost while providing the essential branched chain amino acids (L-Leucine, L-Isoleucine, L-Valine) for maximum protein synthesis during and after exercise. Most bodybuilders know just how crucial glutamine is to helping significantly reduce muscle breakdown, increase protein synthesis, enhance nitrogen retention and promote cell volumization. BCAAs are also at the forefront of providing muscle sparing, energizing, growth promoting benefits. Working together, glutamine and BCAAs provides an explosive one-two punch every athlete needs to load up on before working out.
