Set my lvl in borderlands 2?

i accidently made my self lvl 50 in borderlands 2 with a trainer i downloaded, but i cant change it back?

Do any of you guys have any idea on how i can change it back? (Im using the skidrow version)

Use CE or the likes to lower your exp/level?

But how?

not that easy, all the trainers/codes people have posted allow you only to alter your exp. if you lower your exp to that of a lower lvl, ur lvl stays the same and it just takes longer to pass that level because you put yourself in "negative" exp relative to the level you boosted urself to.
need an actual value in CE that represents your level, not just your exp. still waiting for that myself.
