Amino Build SX-7® Revolution features a potent 10g dose of BCAAs per scoop to help fire up protein synthesis. It also includes musclebuilding ingredients like leucine and betaine, researched to show increased strength, lean muscle and muscle endurance, so you can lift longer and heavier. Finally, we’ve added in a blast of energy in two forms: immediate caffeine and sustained-release caffeine. This formula will help you face your toughest, most demanding workouts. But, we know you’re up for the challenge.


Amino Build SX-7 Revolution is for active men and women who are looking for a BCAA or amino with ingredients to help build strength and muscle that can be taken anytime during the day.


Amino Build SX-7® Revolution features advanced dual-phase ActivSphere® technology and delivers full clinical doses of key ingredients for muscle growth, strength and performance. It delivers clinically dosed betaine, powerful cell volumizers and dual-phase caffeine for enhanced energy, uncompromising power and more explosive workouts!

The key to the effectiveness of MuscleTech supplements are the doses of their key ingredients. While other amino formulas may have some of the same ingredients, only Amino Build SX-7®Revolution has them in doses that correlate to published human clinical studies. Trust Amino Build SX-7 Revolution to be there when it’s time to take your training and physique to new levels, and deliver uncompromising potency and power!


Amino Build SX-7® Revolution features an industry-leading 10g dose of BCAAs supplying a clinically validated 5g dose of L-leucine from three innovative sources – instantized L-leucine, ActivSphere® leucine and PepForm® leucine peptides. These novel forms of leucine work synergistically for powerful anabolic effects!

The 5g dose of leucine not only helps to boost mTOR activation – firing up protein synthesis – but this exact dose was shown in a clinical study to help subjects increase their 5-rep max strength by over 40%!

This groundbreaking study was published in the International Journal of Sports Physiology and Performance. You can read the full research paper here. The formula also features a clinical dose of taurine shown to improve performance in endurance athletes. This study, published in the journal Amino Acids, showed that trained athletes consuming 1g of taurine improved their 3km time trial by 1.7% without significantly affecting heart rate or oxygen uptake! You can view the full research here.


That powerful dose of leucine also works with a scientifically researched dose of betaine for increased strength, lean muscle and enhanced muscle endurance.

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 3.75 lbs. of muscle in 6 weeks – while the placebo group gained just 0.66 lbs. That’s over 5.5 times the muscle gained vs. the placebo group! This exact dose is found in each two-scoop serving of Amino Build SX-7 Revolution. What’s more, betaine has also been shown in a separate study to enhance muscle endurance.

While the latest and greatest stimulants come and go, caffeine is without a doubt an effective and legitimate performance enhancer. However, the days of regular caffeine are gone! Amino Build SX-7 Revolution delivers a dual-phase combination of immediate caffeine plus sustained-release caffeine for a powerful boost in energy, focus and intensity!


Amino Build SX-7® Revolution features a precise combination of three types of leucine – the most powerful of all amino acids for amplifying protein synthesis and maintaining a musclebuilding state.


If you’re looking for a boost in energy, no pre-workout is really complete without caffeine – and it’s one of the top performance-enhancing pre-workout ingredients available. As a powerful central nervous system stimulant, it can really jack up your energy and training intensity. Amino Build SX-7® Revolution features a revolutionary combination of immediate- and sustained-release caffeine to enhance focus and to boost energy and intensity.


The remaining BCAAs in a combination designed to support protein synthesis and muscle repair.


Glutamine is the most abundant conditionally essential free amino acid in your body – more than 20% of the total circulating amino acids in your body are glutamine. Your muscles are especially high in glutamine, making it extremely important for muscle metabolism. It helps support increased cell volume, glycogen replenishment and protein synthesis.


Betaine has the ability to lower homocysteine. Homocysteine can directly impair insulin signaling by reducing insulin receptor stubstrate-1 (IRS-1) activation, which in turn affects muscle protein synthesis. Betaine also acts as an osmoprotectant. This means that it protects the cell against dehydration by acting as an osmolyte, which increases the water retention of cells. Research suggests that a well-hydrated cell can support better anabolism.

Each onescoop serving delivers a precise 2.5g dose of betaine, shown to build 3.75 lbs. of lean muscle in 6 weeks compared to 0.66 lbs. by the placebo group. That’s over 5.5 times the muscle gained (vs. placebo). Betaine has also been shown in a separate study to enhance muscle endurance.


Taurine is one of the most abundant amino acids in the body. It aids in cell volumization, and the 1g dose of taurine in Amino Build SX-7®Revolution has been shown to improve performance in endurance athletes.
