Harness the power of muscle building with PHOSPHATOR™ by pH Labs®. Recently published research involving 8-week clinical trials found that young adult males supplementing with Mediator® Phosphatidic Acid (PA), a patented ingredient compound and the main one found in PHOSPHATOR™, experienced an increase in muscle size and strength in conjunction with adequate protein intake and mechanical muscle activation (e.g. weightlifting).*

How is this possible? Basically, the more protein our muscles can synthesize, the more strength those muscles will have. The pathway that protein (as amino acids) must pass through to get to the muscle is called the mTOR signaling pathway. Without getting too technical, supplementing orally with PA helps to optimize this pathway, thereby maximizing those grueling weight-training sessions for better muscle gains than just weight training alone.
