Mega BCAA Caps

Anti-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!

A very good quality prooduct, at a value price. Taken directly after my workouts, I have reduced soreness and increased recovery time.
