- Build muscle
- Muscle pumps
- Boost protein synthesis
- Improve recovery
Clinically Backed Musclebuilding Formula
How it Works
Muscle Builder works through three mechanisms. First, Peak ATP® increases musclebuilding signaling by activating the mTOR pathway. It also increases skeletal muscle calcium influx and release, which leads to better muscle contraction for improved performance in the gym! Finally, Peak ATP® supports vasodilation and improves blood flow, which delivers more oxygen and can help you push through those last few reps.
Who Should Use it
Muscle Builder is designed for everyone, from active men, women and fitness enthusiasts to high-performance athletes, powerlifters, crossfitters, bodybuilders and endurance athletes. It is also great for individuals looking to boost performance in the gym as well as build more muscle and strength.
One capsule formula!
When to Take
On workout days, take before training. On off days, take before breakfast.
How to Take
Take 1 serving (1 capsule) with a glass of water, 30 to 45 minutes before your workout. On non-training days, take 1 serving on an empty stomach before breakfast.
Powerful Musclebuilding Results with PEAK ATP®
Each serving of MuscleTech® Pro Series Muscle Builder delivers 400mg of adenosine 5′-triphosphate disodium (PEAK ATP®) for enhanced strength and muscle performance. PEAK ATP® is a powerful and unique ingredient that not only delivers some of the most intense muscle pumps you’ve ever felt, but also delivers real gains in strength and muscle!
Hard-training subjects, in a 12-week human scientific study at The University of Tampa, gained 8.8 lbs. of lean muscle vs. the placebo group, which only gained 4.6 lbs. – that’s 90% more lean muscle! In another part of the same study, test subjects increased muscle thickness by 96% more than the placebo group! The same subjects experienced an increase in strength that was 147% more than the placebo group!Wilson et al., 2013. Nutrition & Metabolism. 10:57.
Increases Blood Flow
The PEAK ATP® in Muscle Builder helps increase blood flow and involves an increase of nitric oxide production to induce extreme vasodilation, delivering more oxygen to hard-working muscles — this causes the best muscle pumps you will ever experience!
PEAK ATP® also helps your muscles control ionic flux during contractions, so they can recover and contract faster. Under conditions of fatigue, oxygen availability and calcium release may decline in muscle, negatively affecting overall performance. Calcium is necessary for continued muscular contraction. Therefore, supplementing with ATP may lead to better calcium handling in your muscles for improved performance!
The third and most important pathway of action is when Muscle Builder triggers the musclebuilding mTOR pathway. mTOR stands for mammalian target of rapamycin, one of the body’s protein synthesis regulators, energy sensors and nutrient sensors of amino acid availability — it’s vital for musclebuilding. mTOR is activated when ATP levels are high, and blocked when ATP levels are reduced.
