About Us


Since 1996, no other supplement company in America has offered bodybuilders a more diverse array of products, services and value than ProSource. This success is based on a simple but unique strategy: Offer only the best quality, most research proven supplements available, eliminate the middle-man markups, and keep the prices super low.

As a result, you'll not only find the highly popular ProSource brand of ultra-premium-grade supplements, but you'll also find the greatest selection of bodybuilding's other top-brand products, all at the absolute lowest prices nationwide.

 Most bodybuilder's know that effective physique transformation begins and ends with proper training, diet and superior supplementation, and here again, is where ProSource excels. In an industry too often marked by untested and unproven products, the ProSource brand stands out for its dedication to product research, potency, purity, bioavailability and results!

A great example of this is the highly anabolic NytroWhey® premium whey isolate protein, which was added to the growing line of products in 1997 and with that, the ProSource brand suddenly emerged as the elite choice of the highest-level competitive bodybuilders. And it was just a couple years ago that the continuation of this brand and category reached the pinnacle of achievement with the stunning introduction of NytroWhey® Ultra Elite. This ultra-potent muscle-building technology contains an array of superior anabolic protein content powered by the unprecedented, growth-factor-rich hydrolysate proteins and specially processed, super-amino-rich CFM whey protein isolate from Glanbia® Nutrition, the world's premier protein provider. It also contains a proprietary leucine peptide (Leuvon™ 590) that helps to deliver up to 4 times the leucine content of other premium proteins, among other key anabolic support compounds. Altogether, this amazing breakthrough protein formulation represents the ultimate muscle fuel for bodybuilders.

Another is the legendary test-booster AndroTest®, which was subjected to the rigors of a comprehensive 8-week clinical study to assess its efficacy, the results of which were nothing short of extraordinary. Few products in the test-boosting category have been subjected to even a single day of clinical testing let alone a full 8 weeks of intense scientific investigation. As a result, the power and popularity of this natural, clinical grade testosterone booster has ushered in a new era in the category. This is a further example of the extreme lengths ProSource undertakes to ensure the efficacy of its formulas and your ultimate satisfaction with its products.

For more than a decade now, this uncompromising supplement company has continued to utilize the purest, most potent ingredients from around the globe in an ongoing effort to provide the most efficacious brand of sports supplements available worldwide, including compounds like genuine Creapure® creatine monohydrate from Germany, Tribulus from Bulgaria and the world's purest, most potent aminos from Japan--all the world's best and the list goes on.

On the information front, the ProSource Buyer's Guides and website are recognized throughout the industry as the ultimate resource for insightful articles, extensive product ratings and innovations, sales, promotions, giveaways and, of course, the lowest prices on the greatest selection in the nation.

But without question, the one thing that has contributed the most to this success is the extraordinary quality of the ProSource brand supplements. As a result, they have become the brand of choice for legions of bodybuilders, other athletes, and fitness enthusiasts across the board, nationwide. Ingredient by ingredient, product by product, the ProSource line of premium grade sports supplements emerges superior to any other brands available.

From service to selection to the absolute lowest prices—no one can compete with ProSource—Bodybuilding's Premier Performance Leader!
