I was recommended to this company by a specialist dietician. I am currently undergoing Chemo. and battling with diabetes. I tried the starter pack wich was great,nothing I diidn't like -but at £2 a pack it was a little expensive ,so I opted ffor the larger bag on a subscrive and save option. The service has been excellent, as is the quality and it is just as palatible in smaller fluid quantities, than it is a traditional shake. I need 100 gms protein a day at the moment ,a double dose provides me with a very acceptable 30 gms of protein per day and my Oncologist is greatly relieved I have found something I actually like. Well done Purition
