I would suggest sticking it in the freezer (mild chill so it won't freeze to ice), or in the fridge. Keep it in a sealed, tight container like a tupperware and then wrap it in more plastic. The sooner you use that urine, the better the results of your urine or the other person's urine. Source(s):
Regulus (also known as Alpha Leonis) is a trinary star system at coordinates 3.99S 2.81E in Federation space, known as the Regulan system. Regulus is visible from Earth in the constellation of Leo. The system's three stars include Ra and UFC-113, and are the location of at least thirteen planets.
The story of Romulus, his twin brother Remus, and the founding of the city of Rome is one of the most familiar legends about the Eternal City. The basic legend of how Romulus came to be the first king of Rome begins with the god Mars impregnating a Vestal Virgin named Rhea Silvia, daughter of a rightful, but deposed king.
