D-Aspartic Acid is a non essential amino acid that helps regulate hormones by triggering the release of luteinising hormone, which tells the testes to make testosterone.

This product contains just D-Aspartic Acid as the active ingredient and is offered as a pure, single ingredient supplement with no fillers or additives.

D-Aspartic Acid supports hormone regulation processes that back the body's normal function and energy production.

Some studies hint it might influence testosterone pathways in healthy adult men, matching observations of boosted amino acid synthesis and energy availability.

Dr. Topo from a university found that higher daily intake of D-Aspartic Acid can be linked to rises in natural testosterone levels in healthy men, reflecting its role in hormone signalling and skeletal muscle function.
