Methuselin

Methuselin (メトセリン) is a drug that is briefly mentioned by Touma, as a drug used in the Power Curriculum Program.

Etymology
The katakana used for Methuselin is similar to that used for Methuselah (メトシェラ), the oldest known human character in the Bible, the son of Enoch and the grandfather of Noah.

The name is apparently a pormanteau of "Methusel-" and the suffix "-in".

Principles
Part of the Power Curriculim Program, it is apparently in pill form, and due to its use of the "in" suffix, apparently denotes that is probably a pharmaceutical products, or proteins. It most likely a mind altering substance that aids the user to achieve Personal Reality, though this is just speculation.
