MuscleTech Test 3X SX-7 Black Onyx - 120 Caplets

Test Subjects Increased Testosterone by Over 40%! TEST 3X SX-7TM BLACK ONYX features a precise 3.12g clinical dose of D-aspartic acid. D-aspartic acid (DAA) is naturally occuring amino acid found in the neuroendocrine tissues of humans that has been shown to increase testosterone by over 40% and increase luteinizing hormone by over 30% while staying within the normal healthy range. In one study published in Reproductive Biology and Endocrinology , 23 men were given the same daily dose of D-aspartic acid in TEST 3X SX-7TM BLACK ONYX for 12 days. Researchers found that after 12 days, subjects had increased luteinizing hormone by over 30% and had increased serum testosterone levels by 40%! D-aspartic acid utilizes your body's very own internal mechanisms to raise testosterone, which means there is no feedback inhibition involved and no need for post cycle therapy (PCT). - See more at: http://international.muscletech.com/products/sx-7/test-3x-sx-7-black-onyx/#sthash.C4fXcOPi.dpuf
