Alright, I've run the numbers and you're pretty far over the Total Power Level for Level 1. The biggest problem is Mutagen Mania. I might recommend making it only enhance strength OR speed for now, and limiting the potential somewhat. Something like "Doubles the user's strength to a maximum of 10x the strength of a normal human". That way you can't, for example, give a cocktail to my character and enhance him to 20x ordinary strength and speed. As much fun as that would be, we have to draw a line somewhere.

Depending on how you choose to alter MM, you may also need to reduce the blast size of the bombs, but we can play that by ear.
