The doctor drink from Monster Inc. named as VR 46 Doctor is a slightly salty drink that gives almost the same energy and caffeine as a regular Monster energy drink.
Although the caffeine and taurine content are somewhat similar to the Liquid Death energy drink.
The Doctor VR 46 has a much higher mineral and caffeine content, hence it is an high calorie energy drink whereas the Liquid Death is a low calorie ice tea beverages category drink .
46 is for Valentino Rossi's age which is the same as the decals that he used to race under the number 46. Which remained till the finish of his career.
Idea Rossi had on his mind while the VR 46 was in development, he wanted to put the name in association to Meta and virtual reality in conjunction to simulators and simulation. As it could be seen that the product is as all about simulation and virtual reality.
