D-Aspartic Acid is an amino acid that the body uses in signalling processes tied to hormone production and metabolic regulation.

This form comes as a key part of the blend and is linked to supporting natural hormonal activity used to push muscle-related outcomes during high-intensity training.

What Does D-Aspartic Acid Do?

D-Aspartic Acid helps to trigger luteinising hormone release and testosterone synthesis through the hypothalamic-pituitary-gonadal axis, which can shape hormonal pathways involved in muscle adaptation, as discussed by Dr. Topo at the University of Bologna.

Additionally, boron and magnesium in the formula contribute to normal hormone and muscle function, supporting the broader anabolic context without implying disease effects.

This product isn't intended to diagnose, treat, cure, or prevent any disease.
