Not completely temporary. After every battle, Komaru will keep a chunk of the muscle mass gained from them. So give or take a few more rounds, and she'll really show some gains...

Hmm, temporary? What happens if she downs a whole bottle or so though? Will it become permanent?

Temporary...well, what a pity. There might be something else and "MORE serious".
