[UK People] Protein Supplements

Hi all

Wanting to restrict this to UK people since products on both sides of the atlantic differ....no offence...

Just wanting to know what any UK people use as a Protein shake/drink etc

Looking at things like whey protein mixes in health shops...they are quite pricey and i wanted to know if anyone could recomend a brand/flavour that you have used .... really looking for one that doesn't require too much in the way of mixing or uses Water rather than milk as i live 5 days a week in an isolated (from shops) office and a hotel.

I've been using slimfast stuff before but their pre-mixed shakes a expensive...so looking for something i can bulk buy and mix in hotel room or easily in the office without needing a blender etc

Thanks everyone ... please help !!!

Jamie
