Serum 207. I'm not exactly sure whats in it.

^ i think he is right, but you can't see the potion afterward, since it is untradable

Serum 207 is the cheapest way.

It's tarromin and ashes, real simple to make, like 50 xp each

 

[Determinate]

Energy pots are only 15 gp/xp atm. Might want to try those?
