PhosphaGrow SX-7 Black Onyx from MuscleTech

phosphagrow sx-7 black onyxThe other week at the Arnold was big for many supplement companies, especially with Muscletech, which announced a ton of new products. One being PhosphaGrow. Another product Phospha Muscle, which we talk about here, uses some of the same ingredients you see in this product. The official name is PhosphaGrow SX- Black Onyx. The Black Onyx line is just a stronger and more potent version of other products…good name though, we like it!

What is in PhosphaGrow?

The main ingredient is phosphatidic acid. Why is this ingredient getting so popular? It’s because of a recent University of Tampa study that showed athletes using 750mg of phosphatidic acid for 8 weeks doubled the muscle mass of the athletes that didn’t use phosphatidic acid during their training. Those are some pretty amazing results. Now that is only one ingredient within this formula. The other two ingredients are astragalus root and long jack root.
