re : No Pump Chump
why was L-Arginine not mentioned as it is the primary source of NO?
Under conditions in which nitric oxide is produced for a specific physiologic purpose, the concentration of L-arginine (from which it is formed) can be a limiting factor. When researchers at New York University School of Medicine gave L-arginine to a group of impotent men, six out of 15 men receiving the amino acid claimed an improved ability to achieve erections, while none of the 15 men in the placebo group reported any benefit (Zorgniotti A, Lizza E. Effect of large doses of the nitric oxide precursor, L-arginine, on erectile dysfunction. Int.J. Impotence Res., 1994 6:33-36.)
