The secret ingredient has been proven to increase Testosterone

In the world of alternative Testosterone boosting, there aren’t many ingredients that have scientific studies proving their effectiveness. It is a shadowy world of pseudo-science and unproven claims.

D-Aspartic Acid is an ingredient that has some solid scientific data backing it as an effective Testosterone booster.

A study of 23 humans provides the strongest evidence of the power of D-Aspartic-Acid showing that it acts on cells in the testes which release testosterone or alternatively it changes the behaviour in the hypothalamus or pituitary gland, giving instructions to the testes to secrete testosterone (1).

Another study in 2009 showed that D-Aspartic Acid increased synthesis and release of Testosterone (2).

Another study suggested that D-Aspartic Acid may affect the hypothalamus to increase Testosterone and maybe induce an erection (3).
