Black Onyx™

Doubles muscle gains and increases strength by 60%
Boosts mTOR signaling by more than 6 times*

Contains the only clinically studied & Fully Dosed Form of Phosphatidic Acid
PhosphaGrow™ SX-7™ features the purest clinically tested form of Phosphatidic Acid (PA) available - Mediator® PA. During resistance training, your body naturally produces limited amounts of phosphatidic acid, which binds to mTOR, activating the primary signaling pathway for muscle building. PhosphaGrow™ SX-7™ works through the same mechanism, enhancing mTOR to increase protein synthesis and activate anabolic activity.*

Subjects Boosted mTOR Signaling by More Than 6 Times
In a University of Tampa study, pre-clinical research showed that the same phosphatidic acid found in PhosphaGrow™ SX-7™ increased mTOR signaling by over 6 times compared to baseline!*

Subjects Built Significantly More Muscle & Strength
In a separate phase of the same study, Phosphatidic Acid was shown to double muscle gains in test subjects compared to a placebo. These test subjects gained 5.3 lbs. of lean muscle vs. 2.6 bls. in the placebo group. In the same study, test subjects increased their strenght on the leg press by 60% more than the placebo group (114.4 lbs. vs. 71.4 lbs.) in just 8 weeks! But remember, only Mediator® PA is guaranteed for purity and quality through Nuclear Magnetic Resonance Testing. No other source can deliver the same results! Get PhosphaGrow™ SX-7™ today!*

Good Product
I have been taking this for amount month now and I notice a difference in the way I look. I can increase weight easier in larger muscle groups. I recover easily and ordered two more bottles.

more strength = more satisfaction
I've been using this for 2 weeks and I actually increased weight in my deadlifts and bench press. I've never lifted 2 plates on bench press and it feels great!! I'm definitely gonna keep it going and I can't wait to see the end result.

I thought this product was meant to be for guys who want to build muscle so I didn't want to take it at the beginning, but when I found out that it helps with recovery I jumped right on it! so now no matter if I'm working out regularly or playing soccer, I never get sore anymore. this is really amazing!!!!
