Distinctive cool and edgy logo needed

SuperProtein - Protein just got better

SuperProtein is a new protein supplement company starting with one product - 'Equilibrium' with more products to be introduced in the future. I'm looking for a logo that will help build a strong brand in the very competitive protein supplement market.

BRAND NAME
SuperProtein
Protein just got better

Beginner to intermediate level gym users (not professional body builders)
25 - 44 year old males and females (70% males 30% females)

Distinctive cool and edgy
Quite solid lettering
Metallic/white/grey/brushed metal colour (but please be creative)
I'd like the 2 words (Super & Protein) as 2 different colours or different shades of the same colour
Nothing cheesy like a Super Man logo
The slogan 'Protein just got better' underneath the name
I like the following logos:
EAS - http://www.eas.com (distinctive, friendly and not cheesy)
Blackberry (Friendly font)
Max's SuperWhey (a little too strong and cheesy but it's a good example of how I like the slogan underneath the name)

I'd like a full colour version and a flat one colour version (full colour to be slightly 3D/embossed for the website and products and a flat, one colour version for simple business cards, letter heads etc)
I'd like SuperProtein all in one word and sentence case (SuperProtein)
A SuperProtein emblem design is not essential but if you come up with one that I like then I'd like to see it
I'm open to new ideas (uppercase version - SUPER PROTEIN and also Super and Protein as two separate words on top of each other rather than all one word - in sentence case or uppercase) and different colours so please feel free to come up with your own ideas away from the brief
I will try to give as much feedback as possible on a daily basis (at leqst once per day about 9pm GMT)
