Anyone ever use it?

Supposedly it contains essential vitamins and electrolytes to combat stress and stabilize a reptile that has just moved in, got a new cage mate, etc...

Does this stuff actually do anything, or is it just one of those useless (even harmful) products that pet supply companies have no clue about, but came up anyway to cover an area of the market to get easy money?

I don't see any ingredients on the bottles, and it sounds fishy to me....
