BulkSupplements D-Aspartic Acid Powder (300g)
by BulkSupplements
"3g D-aspartic acid per serving for 100 servings — the bulk testosterone-supporting amino acid at $0.20 per serving"
Overview
BulkSupplements D-Aspartic Acid provides 3g per serving of DAA in unflavored powder form. D-aspartic acid is an amino acid that plays a role in testosterone synthesis by stimulating the release of luteinizing hormone (LH) from the pituitary gland, which signals the testes to produce testosterone. Clinical studies show mixed results: a 2009 study found 42% increase in LH and 33% increase in testosterone after 12 days of 3.12g DAA supplementation, but subsequent studies in resistance-trained men showed no significant testosterone increase. DAA appears most effective in men with suboptimal testosterone levels rather than healthy young men.
