Last week news came in from Muscletech confirming that just as they did to their Hydroxycut SX-7 by turning it into a series. The same thing is going to be done to the more intense Hydroxycut SX-7 Black Onyx. The alternatively themed supplement is soon going to be joined by two more products creating a three formula Black Onyx Series. The items joining the original Hydroxycut Black Onyx are PhosphaGrow and Test3X, PhosphaGrow being one we actually have more information on here today. We do already know the supplement is going to be a phosphatidic acid formula, following in the footsteps of Muscletech’s recently reveled Performance Series product Phosphamuscle. Being a Black Onyx supplement however we knew the brand weren’t just going to throw in phosphatidic acid and leave it at that, seeing as Hydroxycut Black Onyx was really pushed as the more intense version compared to the SX-7 original. It turns out there are in fact two more ingredients in PhosphaGrow alongside the product’s 750mg of phosphatidic acid, astragalus root and long jack root, similar to the make up of Epiq’s self titled Phosphatidic Acid. We don’t know the exact doses of the other two features, although below in the supplement’s facts panel you can see them in order in their 1.529g blend. Like most products Muscletech have packed their first Black Onyx addition PhosphaGrow with enough softgels to last you a full 28 days, leaving price as the only important piece of information left to come.
