Sought by a gang called Sudden-Death Overtime so they might profit from it and bring back ice hockey, the formula is located in the R&amp;D section in the safe on the wall of the Nuka-Cola Plant. R&D is research and developement, and is located in the first area to the left, after entering the plant. You must get the key for the safe from Milo, Shipping Foreman. You must kill him for the key because he will not speak to you. Don't forget to use the computer in the room that Milo, Shipping Foreman is in because it has the shipping manifest of the Nuka-Cola Quantum which will help you complete TheNuka-Cola Challenge. He also holds the password for that terminal. There is no karma loss for killing him.

The gang is located near the Red Racer Factory. You can give the gang the recipe for 250 caps or pass a speech challenge to raise it to 400. Killing Goalie Ledoux, the leader of the gang, doesn't result in any negative Karma, contrary to pickpocketing him in order to reclaim the recipe. Please note that you can't do anything with this formula, so if you choose to kill Goalie Ledoux without selling recipe, you will gain nothing. If you drop the formula before giving it to Goalie Ledoux and then talk to him, he will still accept it and then you can get two (see video).

Behind the scenes
This is most likely a reference to Crystal Pepsi or Tab Clear which was released but was never popular. They were clear or "uncolored" versions of the soda that had the same taste but simply see through. The drinks never caught on and were soon discontinued, though frequently mentioned or parodied in popular culture.
