• MOLECULAR MUSCLE GROWTH - Build muscle tissue at the source! Arachidonic acid is a polyunsaturated fat with the chemical structure 20:4(ω-6). Arachidonic acid plays an essential role in the growth and repair of skeletal muscle tissue and works as an essential dietary component in the muscle hypertrophy process.
• CONCENTRATED FORMULA - Looking for the source? Trace amounts of Arachidonic acid can be found in the food you eat, for example one large hard-boiled egg contains 0.074 gram of arachidonic acid. One capsule of Enhanced Labs Arachidonic Acid contains 350mg of arachidonic acid. You would have to eat 4,730 whole eggs to get the same amount of arachidonic acid!
• CLINICALLY PROVEN - We've done our research! Researchers at the University of Tampa put Arachidonic Acid to the test with a double-blind, eight-week clinical trial.
