INCREASE NATURAL TESTOSTERONE
Research shows that D-aspartic acid (DAA) can accumulate in the testes and may activate the Leydig cells to secrete more natural testosterone.
PITUATARY GLAND ACTIVATION
DAA may also have actions in the central brain region and activate the pituitary gland to initiate more natural hormone production.
In a very well-known study that was conducted in Italy, subjects supplementing with 3,120 mg of d-aspartic acid + vitamins B6, B12 and folic acid experienced an increase in testosterone over the course of just 12 days!
