Protein Shakes

Hi Guys,

I wondered if you would be able to help me i want a new Protein Shake - for workout supplement and/or meal replacement.

I get really confused at what is best as i don't want to get sucked in marketing campaigns! I would prefer lower carb whey option.
I've heard PHD Whey is good but don't want to waste money!!

Any help would be really appreciated! I'm starting Insanity today & form what i hear i think i'm gonna need something to get me through!

Thanks :)
Natalie
