Pro Clinical Muscle Stack SX-7™

The most powerful Clinically studied musclebuildingstack available

  • Subjects gained 18.7 lbs. of lean muscle in 12 weeks
  • Subjects increased strength by 279%
  • Improves peak power, performance, & recovery
  • Full 1-month supply


PEAK SX-7™ is the most powerful pre-workout pill on the market today and CLEAR MUSCLE™ SX-7™ is already the most powerful musclebuilding pill. But did you know that when you combine the two, the sheer gains in lean muscle and strength are unparalleled! In a groundbreaking clinical study at the University of Tampa, test subjects using the PRO CLINICAL MUSCLE STACK SX-7™ gained 18.7 lbs. of pure, lean muscle in just 12 weeks. What’s more, they also added almost 212 lbs. to their best bench/deadlift/squat total. The subjects took part in a hardcore training program that challenged them with every workout and, even the placebo group following the program they built 4.6 lbs. of lean muscle – when is the last time your training program did that? That means when you take this stack, you need to work for your gains, including eating right and taking your training intensity to a whole new level (you can’t just show up to the gym and go through the motions and expect results).


Study #1 - 60 days

Hard-training subjects that supplemented with the key ingredients in PRO CLINICAL MUSCLE STACK SX-7™ over a 12-week clinical study at the University of Tampa gained 18.7 lbs. of lean muscle versus the placebo, who only gained 4.6 lbs.


Study #2 - 8 weeks

Hard-training subjects in the same study increased strength almost 3 times more than the placebo group on their combined maximum weight lifted on the bench press, deadlift, and squat.



The CLEAR MUSCLE™ SX-7™ formula contains BetaTOR™, a unique, cutting-edge metabolite and free acid derivative of leucine and HMB. As you can see to the left, the free acid nature of the compound gives it a viscous, water-like consistency and transparency. In fact, the key ingredient in CLEAR MUSCLE™ SX-7™ appears in the bloodstream quicker, and rapidly absorbs into the muscle for superior results. There is no other supplement like this available.

Once in the muscle, the compound in CLEAR MUSCLE™ SX-7™ activates the anabolic (musclebuilding) process in the muscle called the “mTOR” pathway. This is the universal pathway that must be activated for a muscle to build itself up. The compound also works on a separate pathway – the ubiquitin-proteosome-proteolytic pathway (UPPP), helping to shut down its activity. Normally, when the UPPP is activated, your muscle is broken down (catabolism). But because the compound shuts down (inhibits) the UPPP, muscle breakdown is decreased. So in short, every dose of CLEAR MUSCLE™ SX-7™ amps up your protein synthesis in the muscle while also decreasing muscle breakdown, putting you in the perfect state to build more muscle.


PEAK SX-7™ is an extremely potent formula powered by adenosine 5’-triphosphate disodium (ATP). ATP found naturally in your muscles serves as the primary fuel for muscle cells. New research shows that oral supplementation with ATP in combination with high-intensity training can increase muscle performance, muscle mass, and strength.

How Peak ATP works in the body

Salvia officinalis

Supports vasodilation and increases in blood flow. In fact, researchers have noted that the body has oxygen sensors that release ATP from red blood cells when oxygen is low in the muscle, which in turn may facilitate increased blood flow to deliver the oxygen and energy to help you push through those last few reps. Supplementing with ATP may simulate this natural physiological effect, giving you that extra edge.

Ecklonia cava

Improves muscular strength, power, and endurance by increasing skeletal muscle calcium influx and release. Under conditions of fatigue, oxygen availability and calcium release may decline in skeletal 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.

Increases anabolic signaling by activating the mTOR pathway to initiate protein synthesis, which leads to lean muscle development. With improved nutrient delivery to your muscles, your body is primed for better anabolic signaling and growth.
