Muscle Builder

  • Boosts strength & muscle performance
  • Advanced, university-tested key ingredient


MuscleTech® Pro Series Muscle Builder features the cutting-edge and exclusive musclebuilder PEAK ATP® – and if you haven’t tried PEAK ATP®, you’re missing out on one of the most innovative supplement discoveries of the last decade!

PEAK ATP® is a patented form of adenosine 5’-triphosphate (ATP) disodium and is without a doubt the most powerful pre-workout musclebuilding ingredient available. ATP found naturally in your muscles (intracellular) serves as the primary fuel for muscle cells. However, the extracellular ATP that PEAK ATP® provides is just as important, as research suggests boosting levels of ATP in the blood helps to increase blood flow and supports improved muscular strength and endurance, while at the same time increasing anabolic signalling by activating the mTOR pathway! Research now shows that supplementing with PEAK ATP® in combination with high-intensity training can increase muscle performance, muscle mass and strength!

Incredible Study Results

Hard-training subjects participated in a gold-standard 12-week human study at The University of Tampa to determine the effectiveness of PEAK ATP®.  These subjects used the exact same dosing protocol of PEAK ATP® as MuscleTech® Pro Series Muscle Builder.

How Muscle Builder works


This one-of-a-kind, cutting-edge formula is engineered to deliver powerful musclebuilding results. Each serving of MuscleTech® Pro Series Muscle Builder delivers 400mg of adenosine 5′-triphosphate disodium for enhanced strength and muscle performance when used with a resistance training regimen and a balanced diet. There is no other formula like this, and it is available exclusively from MuscleTech®.


PEAK ATP® increases anabolic signalling by activating the mTOR pathway. It also increases skeletal muscle calcium influx and release, which leads to better muscle contraction for improved performance. Finally, PEAK ATP® supports vasodilation and improves blood flow, which delivers more oxygen and can help you push through those last few reps!


Each bottle of MuscleTech® Pro Series Muscle Builder features fully disclosed ingredients with nothing hidden inside proprietary blends. Also, each batch of MuscleTech® Pro Series Muscle Builder undergoes strict quality control and is third-party tested and verified to ensure that each bottle meets the highest standards of purity, quality and consistency. You can trust that what is listed on the label is in the bottle!
