Overview

BulkSupplements D-Aspartic Acid provides 3g of pure D-aspartic acid (DAA) per serving with no fillers, flavors, or additives. DAA is an amino acid that plays a role in the synthesis and release of luteinizing hormone (LH) from the pituitary gland, which in turn stimulates testosterone production in the Leydig cells. Clinical studies have shown DAA can increase testosterone levels by 30-60% in men with low-normal testosterone over 12 days of supplementation. However, effects may normalize after 30+ days.
