Once the body fat index is at the lowest possible level, the only thing that can worsen muscle definition is water. Lasix is used to eliminate from the body as much water as possible and ultimately increase the muscle definition. Bodybuilders use Lasix only for a short period (3-5 days) before the contest because Lasix has a powerful effect on potassium, sodium, calcium, and electrolyte levels.
