I am rather pleased with the hue of yellow lended to urine after I have ingested large amounts of B-Complex vitamins. It almost glows in the dark it is so damn bright.
The other yellow hue that is preferable is that created recently as I have been ingesting lots of weight lifting supplements and other metabolic optimizers which are of extremely variable origins, including nitiric oxide, creatine monohydrate, glutamine, L-arginine, long chain carbohydrates, vanadyl sulfate, ephedrine, caffeine, and aspirin. That is like super yellow pee pee that would make a physician freak out if he saw it as part of an annual physical. I can't imagine how muc effort it takes for my kidneys to process all that stuff. Haaa!!!! :yim_rolling_on_the_
