Builds Muscle and enhances performance

Branched chain amino acids (BCAAs) have been used by top bodybuilders and other athletes for years due to their ability to support training endurance and recovery! BCAAs are comprised of three powerful amino acids – leucine, isoleucine and valine – and are perfect for any hard-training athlete because they serve as primary building blocks for muscle and help combat muscle loss and protein breakdown, especially during intense training.

And while many BCAA powders deliver these basics, most BCAA or amino powders are not based on scientific research, nor are they designed to enhance performance. MuscleTech® researchers knew this when they created the original AMINO BUILD® formula, and that’s why they engineered more than just another “me too” amino formula. Instead, AMINO BUILD was developed with elite athletes in mind and formulated with scientifically researched ingredients that drive peak performance – including a massive dose of BCAAs and scientifically researched doses of leucine and betaine that other amino formulas simply didn’t have.


The Scientifically Dosed Muscle- & Performance-Enhancing BCAA Formula

Now MuscleTech® researchers have taken this most powerful amino acid formula and made it even better! Introducing AMINO BUILD® NEXT GEN! This powerful new formula updates the original AMINO BUILD formula with a new electrolyte complex and even better flavour! And unlike other underdosed products that have little or no research to back up their claims, AMINO BUILD NEXT GEN is back by four different scientific studies that demonstrate its muscle-, strength- and performance-enhancing abilities!

Delivers 8g of BCAAs

This powerful pre- and intra-workout complex contains a massive 8g dose of 100% free-form BCAAs (per 2 scoops) in the ideal 2:1:1 ratio to help fuel skeletal muscles, preserve muscle glycogen stores and reduce protein breakdown.

Contains a Scientifically Studied Dose of Betaine for More Lean Muscle

Each two-scoop serving of AMINO BUILD® NEXT GEN also features a scientifically studied 2.5g dose of betaine added to the formula that helped subjects significantly enhance their muscular endurance. This 2.5g dose also helped test subjects pack on lean muscle!

Provides a Precise Electrolyte Complex

AMINO BUILD® NEXT GEN is a truly complete formula featuring precise doses of coconut water and watermelon juice as well as electrolytes to help replenish electrolytes that are lost during hard training.

Powers Endurance Performance with a Scientifically Studied Dose of Taurine

Each two-scoop serving of AMINO BUILD® NEXT GEN features a 1g dose of taurine, which is scientifically shown to improve athletic performance in endurance athletes.

Test Subjects Built 3.75 lbs. of Lean Muscle!

Betaine has quickly become a staple of many athletes’ supplementation plans because of its ability to deliver real musclebuilding results. With the launch of the original AMINO BUILD® formula, Team MuscleTech® researchers were amongst the first to include a clinical dose of betaine in any supplement, and the science continues to support this amazing ingredient!

In a 2013 study featuring 23 experienced strength-trained men between the ages of 18 and 35 conducted at a leading American university and published in the Journal of The International Society of Sports Nutrition, researchers found that subjects who supplemented with 1.25g of betaine twice a day with weight training gained lean muscle.

Scientifically Shown to Boost Strength

Leucine plays a central role in muscle growth. In fact, it’s the key dietary amino acid that has the capacity to stimulate muscle protein synthesis. It does this by stimulating mTOR, the body’s master protein synthesis regulator. This makes the leucine content of AMINO BUILD® NEXT GEN key to getting real results, and one of the reasons why MuscleTech® researchers include 4g in each two-scoop serving, while most other amino formulas come in underdosed on this critical amino acid.

AMINO BUILD NEXT GEN is formulated with the exact 4g dose of leucine shown in a research study conducted  (from a leading international university) help subjects increase their 5-rep max strength. These are incredible results!

Enhance Endurance and Performance with the First Dose!

Taurine is one of the most abundant amino acids in the body and plays a variety of roles – one of which is to support endurance performance.

A 2013 study found that the 1g dose of taurine found in a full two-scoop serving of AMINO BUILD® NEXT GEN improved performance in endurance athletes. This study showed that trained athletes consuming 1g of taurine improved their 3km time trial by 1.7% without significantly affecting heart rate or oxygen uptake!

This study was published in the journal Amino Acids. You can check out the full research here:

Best-in-Class Taste!

AMINO BUILD® NEXT GEN is flavoured by experts in one of the world’s top flavouring houses in order to taste better than any other amino acid powder on the market. Whether you drink it while you work out our sip on it throughout the day, we’re confident you’ll love the new and improved flavours that AMINO BUILD NEXT GEN delivers!
