Introducing new MuscleTech® Phospha Muscle™ – a shockingly powerful musclebuilder evolving from a breakthrough new study from The University of Tampa. In this study, researchers finally exposed the anabolic potential and incredible musclebuilding effects of phosphatidic acid. Phosphatidic acid naturally increases in the body during resistance training and binds to mTOR, thereby increasing protein synthesis. MuscleTech® Phospha Muscle delivers the purest form of phosphatidic acid to boost these effects and give you the size and strength you want!*
By now you’ve likely heard of phosphatidic acid, as it’s quickly become a staple in the arsenal of some of the best bodies on the planet, including record-chasing athletes who are looking everywhere for an edge in sports that are often decided by the smallest of margins.*
Phosphatidic acid is an important signaling lipid that plays a role in a range of biological processes, including protein synthesis. It is a major part of cell membranes and plays several roles in the functioning of cells.
However what’s most important to anyone looking to build more muscle is that phosphatidic acid has been shown to activate the mammalian target of rapamycin complex 1 (more commonly known as mTORC1) signaling pathway, enhancing the effects of weight training.*
You’ve probably heard of mTOR – the pathway responsible for protein synthesis and muscle growth. mTOR is a multi-domain protein kinase that interacts with other proteins to form two main types of complexes: mTOR complexes 1 and 2 (mTORC1 and mTORC2).
Signaling through mTORC1 is much better understood than signaling through mTORC2, and as such, it is known that it plays a major role in cellular regulation, impacting cell growth (including muscle growth). Signaling through mTORC1 is activated by hormones and growth factors, and requires amino acids. mTORC1 can be negatively regulated by stressful conditions, such as decreased energy (ATP) availability.*
mTORC1 can also be activated by exercise. When we work out, the fibers that receive the mechanical stimulus of an external load trigger the release of phosphatidic acid inside the cells. Phosphatidic acid then binds to mTOR and activates mTOR complex 1 (mTORC1), which causes the growth and repair of muscle. If you want to build muscle, you have to activate mTORC1, and the more phosphatidic acid available, the more amplified the effect on intracellular protein synthesis and, ultimately, on muscle gains.*
And now, scientists have discovered that introducing phosphatidic acid via supplementation while following a resistance-training program has this exact same effect on mTOR activation!*
The first phase of the research on phosphatidic acid was determining what source of it increased mTOR signaling the most. In pre-clinical research, scientists tested various sources of soy- and egg-derived phosphatidic acid, and reported their findings in data published in Nutrition & Metabolism, unveiling that soy-derived phosphatidic acid (Mediator®) increased mTOR signaling the most – by 6 times compared to baseline and kept it elevated for more than 6 hours!*
Then the true anabolic powers of phosphatidic acid were unleashed upon a group of trained individuals at The University of Tampa where the results were nothing short of incredible!*
Subjects supplementing with Mediator® PA – the exact form of phosphatidic acid found in MuscleTech® Phospha Muscle™ – packed on 5.3 lbs. of solid, lean muscle in just 8 weeks. This was double the muscle that the placebo group gained over the same time period!
In the same study, test subjects increased their strength on the leg press by 60% more than the placebo group in just 8 weeks!
What’s more? Subjects only trained 3 times a week. Just imagine how much muscle you could build with your own hardcore training program that incorporates multiple growth cycles in the same week!*
Each batch of new MuscleTech® Phospha Muscle™ undergoes strict quality control and is third-party tested and verified to ensure that each bottle of Phospha Muscle™ has the highest purity, quality, and consistency.
The results of this groundbreaking study place phosphatidic acid firmly in the category of “must haves” for any bodybuilder or strength athlete looking to make the most gains from training. In the study conducted at The University of Tampa, subjects took 750mg of PA daily. MuscleTech® Phospha Muscle™ contains the exact amount and type of PA used in the study (Mediator®), taking the guesswork out of which product to choose to make the most of this exciting new ingredient.
MuscleTech® Phospha Muscle™ has been tested and verified by a specialized testing procedure called Nuclear Magnetic Resonance (NMR) spectroscopy. This analytic chemistry technique guarantees the content and purity of a sample as well as its molecular structure.
There are many imitators on the market today with products claiming to contain phosphatidic acid. This makes it extremely important for consumers to stick with proven brands that only use Mediator® Phosphatidic Acid, and use the full, disclosed dose of 750mg. If you see a product without the Mediator® logo, or if their phosphatidic dose is not disclosed, steer clear, as it will likely contain untested materials in questionable doses! However MuscleTech® Phospha Muscle™ can be truly relied upon to deliver the clinically validated dose of Mediator® Phosphatidic Acid that you want.*
MuscleTech® Phospha Muscle™ is enhanced with a tested dose of tart cherry, shown in emerging research to support recovery and fight catabolism.*
Use MuscleTech® Phospha Muscle™ every day to provide both potent anabolic and anti-catabolic power at the same time, so you get uninterrupted gains in size, strength, and performance!*
