Patrick Flanagancrystal Energy 4Oz by Patrick Flanagan

I'm wondering if someone could comment on the difference between this product as compared to the Megahydrate

What is the complete ingredients list for Crystal Energy? Thank you.

Exactly how many liters will one 4 oz bottle treat?--or how many drops are in a 4 oz bottle? Thank you.

Product shows for 4 ozs being sold by dr dry for $30, and on dr. flanagan's actual website that bottle sells for $45 - is this the real deal or fake?
