Mass and Strength Builders

For bodybuilders looking to add serious size to their frame, in the form of lean muscle, of course, while minimizing fat gains, or any athlete looking to bulk up muscle mass, the popular solution is Mass Building supplements. These products are specifically formulated to help you pack on pounds of lean mass, which is why the mass-building category is one of the most crowded and fiercely competitive of all in today's sports supplement marketplace. When you think mass building, you probably think of creatine, a natural derivate of an amino acid produced in the body that supplies energy to muscles. Supplementing with creatine products, such as MHP's Dark Matter or BioQuest's MyoZene, helps you train harder before fatigue sets in while also hydrating muscle cells. Aside from creatine, mass-building products often contain additional branched chain amino acids (BCAAs), such as glutamine, beta alanine, taurine, tyrosine, tryptophan and leucine. Formulas for various fitness goals exist, including sugar-free to help keep your carb intake low or the inclusion of protein, carbohydrates, fat and electrolytes to make up an all-in-one powerhouse product. If your pursuit for more muscle seems never-ending, this mass-building supplement category is the answer you've been looking for.

    ZMA by ProSource 100% SNAC Systems ZMA -- The World's Best Supports Free and Total Testosterone Levels Key Component to Overnight Muscle Recovery Significant Strength Gains Validated in University Testing Supports Sleep Efficiency Works Synergistically with Other T-Boosting Supplements ProSource ZMA is the same premium grade form of this amazing multi-compound powerhouse that has been proven effective in university research showing significant gains in college athletes. SNAC (Scientific Nutrition for Advanced Conditioning) Systems has long been the leader in ZMA research and development. This should not be surprising given the fact that SNAC pioneered, formulated and introduced the very first ZMA product. In keeping with its research criteria, SNAC uses only the highest quality zinc, magnesium aspartate and vitamin B6, and in the exact ratios used in the study. Benefits of ZMA Independently, zinc has long been recognized for its vital role in testosterone support. For athletes specifically, it is important to understand that strenuous physical exercise causes significant decreases of zinc in the body, and studies have shown that even small deficiencies in zinc can lead to reductions in testosterone production. There is also evidence that zinc has antioxidant activity, so it may help fight free radicals generated during exercise that can hinder recovery. Magnesium has been linked to helping sleep efficiency, muscle recovery and other valuable health benefits. Vitamin B-6 is a pivotal element to the mix because it helps to enhance the utilization and synergy of the two key compounds. Together, in a precise ratio, ZMA has a long documented history of supporting significant strength gains along with improvements in free and total testosterone levels. As if this isn't enough, ZMA is also one of the most affordable T-boosters on the market. Though it doesn't have the unprecedented T-boosting power of an advanced technology like ProSource's AndroTest, it does have a great price, proven performance results and premium quality ingredients, so it's no wonder ZMA holds strong in this category. It works perfectly as a stand-alone or can be incorporated into other supplementation regimens for added effect. Combat zinc and magnesium deficiencies, help boost testosterone levels and increase your strength and growth potential with this immensely popular anabolic agent.

    Creatine Monohydrate by ProSource Contains 100% Creapure® Creatine, the World's Purest, Most Potent German Creatine Monohydrate The introduction of creatine over 25 years ago represented a landmark moment for our industry. Few compounds since then have changed the sport of bodybuilding as dramatically as this remarkable mass builder. Yet, because of its popularity now as a must-have supplement, as well as the existence of fly-by-night companies out to make a quick buck, no other compound varies as widely in quality from brand to brand. Making the informed choice is critical to the success of your workout and supplementation regimen. Fortunately, clearing up the confusion over creatine is a relatively simple task. That's because there's really only one form of creatine that delivers the phenomenal increases in size, strength and power that this super-supplement has become famous for. It's AlzChem Creapure® Creatine Monohydrate. And it's available right here with ProSource!This premium Creatine is recognized by top researchers the world over as the superior premium-grade formula and the only Creatine that yields a true 100% purity level. Most other Creatines (domestic, Chinese, Austrian, etc.) are inferior imitations at best, chock full of impurities such as dihydrotriazine, creatinine, sodium, and dicyandiamide. Creapure® Creatine used in the ProSource brand is the purest, most potent form of creatine monohydrate you can find anywhere. This unequalled purity level, combined with its superior micro-crystalline consistency can mean greater absorption, greater cell volumization and greater gains in lean muscle growth than you can achieve with any other Creatine.Since the early days of our industry, hundreds of products and manufacturers have come and gone. Over that time, however, a handful of companies have distinguished themselves by doing the research, demanding only the best ingredients available worldwide and developing them into a premier line of performance supplements. ProSource was a major contributor to that movement then, and continues to lead the charge today. If you've already added ProSource Creatine to your workout regimen, then you know the difference premium quality can make. If not, find out for yourself.

    MyoZene by BioQuest Ultra-Rapid-Action, Super-Anabolic Mass Builder Ultra-Fast-Acting Whey Hydrolysate Jumpstarts Growth Leuvon 590 Leucine Peptides Supercharge Muscle Anabolism Potent Amount of the World’s Best Creatine (Creapure®) Delicious New Gourmet-Quality Flavoring System Clinically Validated Gains in Product-Specific Testing Best Selling Mass Builder in ProSource Retailing History For a significantly stronger, more massive physique, no other mass-builder on the market today can compete with MyoZene. The original formula delivered such impressive results that it had the most hardcore athletes buying it up by the case. The innovators at BioQuest then reformulated this magnificent post-workout to provide even greater anabolism. They also incorporated a new, cutting edge flavoring system for a lighter, more delicious taste. MyoZene’s increased muscle-building power arrives by way of the inclusion of Leuvon™ 590 Leucine Peptides, a revolutionary patent-pending peptide carrier technology that enables leucine to remain soluble and stable, primed to super-efficiently trigger muscle synthesis through the mTOR pathway. It is well known that leucine is one of the key three in the BCAAs (isoleucine and valine being the others), and of them, it’s the most critical to activating muscle protein synthesis. Leuvon™ 590 offers the most bioavailable form of leucine known to science, which ensures maximum efficacy. A Powerful Matrix of Advanced Growth Catalysts MyoZene’s core strength originates from its rare and highly specialized whey hydrolysate technology, which is a direct result of an extensive hydrolysis, yielding extremely low di- and tri-peptides that are absorbed directly into the bloodstream, and therefore, are more directly utilized for muscle synthesis. It’s well established that the ingestion of premium hydrolyzed whey protein immediately after exercise results in the highest levels of blood amino acids, which are associated with augmented nitrogen utilization, protein synthesis and a greatly elevated anabolic state. Based on its peerless anabolic success, other brands have recently introduced semblances of hydrolyzed whey into their formulas, but their lesser quality, quantity and degree of hydrolysis are no comparison to the highly specialized form found in MyoZene. In addition to its unmatched whey hydrolysate, MyoZene also contains potent amounts of Creapure® creatine monohydrate (the world’s best), a highly bioavailable N-acetyl-L-glutamine, and L-Carnitine L-Tartrate, which upregulates androgen receptor content and helps augment luteinizing hormone secretion. These additional anabolic amplifiers combine to drive truly phenomenal increases in recovery, strength and size. And the customer feedback on this powerhouse formulation is still coming in loud and clear, years after the initial breakout success of this best-in-class mass builder. At that time we were in awe of the amazing results MyoZene could produce, and more amazed by the short amount of time it took to see these results, in some cases just 7 days to start noticing significant muscle gain. But this is only part of the story. Once a large number of bodybuilders saw what it could do, the demand for MyoZene was overwhelming, with reports of size gains unlike anything seen with standard whey proteins. With all these consumer accolades, there was no doubt that MyoZene was the next evolutionary step in-post workout formulations. A Landmark Brand-Specific Clinical Study As further proof, MyoZene continues to be firmly established as virtually the only mass-builder clinically validated in a product-specific study linking it to significant strength/muscular endurance increases. In that 4-week clinical study, a MyoZene-receiving subject group experienced gains of 24% in strength/muscular endurance at the mid-study point, and an impressive 32% at the end of the study. At the same time, the MyoZene users actually reduced some body fat as well. Rarely, if ever, has a nutritional technology yielded such power to produce measurable increases in lean muscle in such a short time. Ultimately, these stunning results alone should alleviate any remaining doubt about its extraordinary mass-building power. Gourmet Flavor AND Advanced Muscle Support Finally, MyoZene’s advanced new flavoring system has dramatically improved the taste of all three original flavors of MyoZene, while adding a great new fourth flavor, Strawberry Kiwi. The post-workout category is arguably the most important window of mass gain opportunity in all supplementation. This is the one area you must be sure of in order to grow as quickly and as efficiently as possible. All things considered, MyoZene remains the ONLY super-potent mass-building, post-workout option for the truly serious bodybuilder.   1 Lou L, Kalman D, Feldman S, Krieger DR.

    PROSOURCEANDROTESTTrue Clinical Grade Test Boosting Power Natural, Clinically Tested Active Ingredient Matrix Ultra Bioactive Testosterone Enhancement Power Full Spectrum, Protodioscin-Rich Super Compound Up to a 217% Increase in Free Testosterone Up to a 275% Increase in Total Testosterone With AndroTest®, the ProSource research and development team has ushered in a new modern era of T-boosting science. What separates AndroTest from virtually every other T-booster out there is its superior degree of standardization and unrivaled potency. AndroTest’s key ingredient, a full-spectrum protodioscin-rich botanical super-compound, is synthesized via a painstaking refinement method that can include up to 20 separate extractions. The result is the first T-booster ever standardized for a minimum of 40% bioactive protodioscin levels. Research has established that protodioscin is a key catalyst responsible for helping to enhance the production of luteinizing hormone (LH), which in turn, helps raise testosterone levels in the body. Many bodybuilding experts consider this to be the ideal mechanism for raising test levels because it works by stimulating the natural production of the body’s own testosterone rather than relying on the artificial replacement of it as is the case with synthetic testosterone drugs.What’s more, this superior-grade driver of testosterone support is also standardized for a minimum of 60% furastanol saponins and 80% total saponins content, yielding the most potent and complete spectrum of active T-boosting components in existence. Given this due diligence in standardization and manufacturing protocols, it should come as no surprise that AndroTest has made headlines in the realm of independent clinical research.In a randomized, placebo-controlled, double blind clinical study, AndroTest produced statistically significant increases in total testosterone levels, averaging 59.88% over baseline, with some subjects showing total increases as high as 275% over baseline. And major increases in free testosterone, averaging 59.75% over baseline, with some subjects reaching up to 218% over baseline. This means that some subjects using AndroTest experienced nearly a three-fold increase in testosterone levels. Equally impressive is the fact that the increased testosterone levels (after two weeks use) were observed throughout the measurement points of the study, which is especially important since sustained increases in testosterone are the key to enhancing muscle growth.When it comes to driving natural T-level increases that serve as the solid foundation for optimum performance, there’s simply no viable alternative than the one and only, clinical strength AndroTest.   *Not Available In California More about AndroTest: Get the Alpha Male Advantage Man Up!

    PROSOURCETRIBUTESTPotent Tribulus terrestris extract for high-quality T-boosting power 1000 Mg High-Grade Bulgarian Tribulus Terrestri Highest Potency In Its Price Range Standardized for 40% Total Saponins Ultra-Pure Quality Extract When searching for a quality T-booster at an economical price it is highly recommended that it be an extract of Tribulus terrestris from Bulgaria, and, that it be a ProSource product to ensure optimum quality and efficacy. This is particularly important since there is such a wide disparity that exists among supplements in this category. Fortunately, ProSource TribuTest takes the guesswork out of the equation by providing a powerful and ultra-pure product that supplies 1000 mg of genuine Bulgarian Tribulus extract. Tribulus from Bulgaria has been documented to yield significantly higher potencies and powerful saponins not found in tribulus from other parts of the world. TribuTest is specially processed to yield a highly bioactive standardized extract (40% minimum steroidal saponins). The only tribulus products we've seen that offer higher value are the AndroTest formulations, which dominate this category, and for very good reason. For those athletes on a tighter budget, however, TribuTest is a potent and praiseworthy alternative.

    PROSOURCETONALIN CLA Stimulant-Free Diet Support Standardized for an Unprecedented 80% CLA Key Support of Body Repartitioning Nutritional Support of Good (HDL) Cholesterol Combine with Stimulant-Based Supplements for Added Effect This versatile and popular body-toning lipid has been the subject of a significant amount of scientific research and clinical studies focused on its ability to help support repartitioning (reduction of the abdominal area while enhancing muscle tone) and support of good (HDL) cholesterol. In addition to its body repartitioning qualities, there is also solid evidence of CLA’s ability as a powerful antioxidant and immune system enhancer, among other health benefits.CLA is classified as an essential fatty acid, which is found in some food sources, like meat and dairy products, but because of today’s agricultural practices, it is no longer available in these natural sources in amounts of any benefit. Because of this fact, and the ongoing research that shows remarkable advantages yielded by CLA, it has become a popular ingredient in supplemental form. And along with that are brands that shortchange the quality and potency in order to make a quick buck off the growing popularity of this compound. Once again, you need to trust the product and the brand before investing your time and money.Keep in mind that the Tonalin® brand of CLA has long been the gold standard in this category, and remains the most tried and true form. ProSource Tonalin® CLA contains a full 1600 mg per serving of highly potent and pure material standardized for 80% Tonalin® CLA, the highest quality available.Tonalin® CLA is ideal for those who are sensitive to stimulants, or for those who would like an effective transformational product to stack with their stimulant-based thermogenic or other diet support regimen.

    ProSourceSuper AKG Nitric Oxide Potentiator 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.

    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.

    Beta AlaninePowerful Support for Endurance Clinically Validated to Significantly Increase Carnosine Levels Shown to Help Reduce Fatigue Premium Grade 100% Pure Amino Acid Helps Augment Energy Levels During Intense Workouts Most exercise physiologists agree that to increase strength and muscle mass it is essential to reduce fatigue during workouts, and one way that may help is beta alanine supplementation. This precursor to carnosine synthesis has been shown to elevate muscle carnosine levels by more than 60% in clinical studies. This is important to your routine because increased muscle carnosine levels are associated with increased energy production and workout capacity. Indeed, a number of published, well-controlled scientific studies have indicated that supplementation is an effective dietary strategy to improve and maximize the performance of intense, maximal exercise, especially workouts or protocols that involve longer exercise bouts or repeated exercise bouts with limited recovery. An article published in 2012 took the approach of summarizing a large group of studies already published on beta-alanine.  This article considered several different patterns of supplementation and involved over 350 research subjects.  When all of these measures were considered, the authors concluded that beta-alanine significantly improved outcome measures when compared to a placebo.  In particular, beta-alanine improved and maximized the capacity to perform maximal exercise in both the short and longer (1 to 4 minutes) term.1Its unique workout enhancement ability plus stellar user reviews have made this remarkable amino one of our best sellers. As with all ProSource brand products, ProSource’s Beta Alanine is 100% pure and potent to ensure maximum efficacy.1 Hobson, RM, et al.
