Numerous studies have shown that the powerful trio known as branched chain amino acids (BCAAs) can help prevent muscle breakdown, support muscle protein synthesis, accelerate recovery and promote anabolic hormone production after a workout. Consisting of leucine, valine and isoleucine, BCAAs are the three most important of the essential amino acids. They make up one-third of the total amino acids in the body's muscles and are metabolized directly in muscle tissue instead of the liver.

    A-Bomb by MHP Advanced Potency Amino Acid Complex A-BOMB supplies the most critical muscle building agents needed to fuel your body during intense physical training. It is the first supplement designed to trigger multiple anabolic actions while simultaneously shutting down catabolism (muscle wasting) during and after intense exercise and weight training. Muscle growth and recovery can only occur if the body remains in an anabolic/anti-catabolic state. A-BOMB has been precisely formulated with select performance enhancing compounds, co-factors, amino acids, branched chain keto acids and branched chain amino acids to fuel your body during training and ensure that you remain in this favorable state for maximum muscle growth, recovery and performance.

    L-Leucine100% Pure Form of the Protein-Synthesizing Amino Long associated with the related BCAAs, isoleucine and valine, leucine has lately emerged as a uniquely powerful anabolic agent in its own right. In clinical testing, leucine has demonstrated a remarkable capacity to decrease protein degradation and improve protein synthesis, especially after intense exercise. Athletes have been looking for leucine in its pure form thanks to its ever-expanding reputation for driving improved anabolism. ProSource L-Leucine is one of the few leucine supplements available in a 100% pure, high-potency form.   Learn more about L-Leucine and Amino Acids: Amino Acids: The Ultimate Guide to Amino Acid Supplementation  Read Reseach Articles: Protein And Leucine Are Anabolic In Both Young And Old Subjects Leucine Drives Protein Synthesis Leucine Enhances Effects Of Whey Protein HMB Positively Affects Nitrogen Balance Click to read about An inside look at the ProSource headquarters: See What Sets Our Brand Apart

    Myo-SurgePowerful Anabolic Pre-Workout Formula Most athletes recognize the importance of nutritional supplementing after exercise. Many do not know, however, that fueling up on essential BCAAs and glutamine before working out is every bit as important to the mass-building equation. In fact, one major study has indicated that pre-workout supplementation may be superior to post-workout supplementation when it comes to enhancing protein synthesis(1). 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 a wide array of essential branched chain amino acids for maximum protein synthesis during and after exercise. In recent clinical research, glutamine and BCAAs have also proven indispensable in reducing muscle breakdown, increasing growth hormone levels(2), enhancing nitrogen retention(3) and glycogen synthesis, and blocking cortisol production.

    BCAA Max 1000mg Of Free-Form Essential BCAAs Per ServingWith BCAA Max, you get a full 1000mg of the purest "uncoupled" (free form) branched amino acids available. These three "essential" aminos (leucine, valine, isoleucine) are formulated in the precise and proven 2:1:1 ratio. As informed strength and endurance athletes know, BCAAs are important as they are directly metabolized in the muscle rather than the liver. In other words, after digestion, BCAAs are readily available for the muscles to use as needed. BCAAs also play a crucial role in maintaining anabolism and decreasing muscle catabolism by promoting protein synthesis, enhancing nitrogen retention, preventing muscle breakdown, providing fuel for muscular energy, increasing the anabolic hormone response to exercise, as well as alleviating fatigue. Vitamin B6 has been added to enhance overall BCAA utilization and absorption.Branched-Chain Amino Acids Scientifically-Proven 2:1:1 Ratio Helps Promote Protein Synthesis Anti-Catabolic Amino Acids

    Monster Amino BCAA by CytoSportUltra-Concentrated Anabolic Amino Acid Formula Monster Amino is an ultra-concentrated BCAA formula that delivers an 8:1:1 ratio of Leucine to Isoleucine to Valine. Recent university research shows that Leucine enriched beverages consumed with exercise synergistically activate and prolong activity of the mTOR signaling pathway, which increases muscle anabolic potential (muscle growth). The mTOR pathway is the "trigger" that signals the very genesis of muscle protein synthesis. Monster Amino is able to achieve the anabolic 8:1:1 BCAA ratio by combining PepForm Leucine Peptides, and free-form L-Leucine, L-Isoleucine and L-Valine for maximum muscle-building performance.
