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.
LA Muscle tends to stay away from anything that has not been scientifically proven to have an effect on the body, whether for fat burning or muscle building.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).
If you are considering a scientifically proven ingredient that can dramatically increase Testosterone, build more strength and muscle mass, then Norateen Heavyweight II has the right amount of D-Aspartic Acid as well as several other powerful muscle building ingredients.(1) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5340133/
