Phosphatidic Acid or Mediator is a naturally occurring phospholipid that is vital in the functioning of cell membranes and initiating cell signaling -- namely mTOR and the proliferation of muscle cells. There have been several published research papers demonstrating Phosphatidic Acid to stimulate mTOR signaling pathways --- which basically means this ingredient will initiate muscle protein synthesis and spark potential muscle growth, and strength gains.
One study showed subjects taking 750 mg of Phosphatidic Acid per day combined with resistance-training 4x a week achieved 50% greater increase in muscle cross-sectional area and lean body mass. A 40% greater increase in total strength (upper and lower body), and 60% greater loss in body fat than the training-only group.
