Arginine showed up as a red skinned person. I got a symbol of two V's connected by lines. He told me was useful for helping with the circulation of blood and reducing stress, especially for circulation for the internal organs. I've worked with Arginine before, a few years ago, and I did find it useful for lowering stress and developing better circulation. Testosterone showed up as a brash noble, the symbol was a sword (how phallic). The sensation of working with testosterone was centered in the testes and there was a sensation of libido rising as well as the feeling of "maleness" for lack of better word.
