Now Foods Whey Isolate and Dymatize Casein.
I've found that I get better results with the Whey Isolate only for post workout, and Casein any other time (especially just before bed).
That said, I cook my food for the day when I wake up, then pack em in 3 Lock N Lock boxes and eat half a box every 2-3 hours. Whey after the waking workout, Casein before bed, an occasional Casein shake mid-day.
P.S. used to like Syntha-6 back before I started cooking and packing my meals. Actually read the label one day. IIRC, my 2-scoop (~50gm of protein) serving had something like 40% of the recommended daily cholesterol. I was drinking 3 of those a day
That's what made me look for pure whey isolate with as little 'additions' as possible. The same 2-scoop 50gr protein serving of the Now Foods Whey Isolate has something like 2% of the daily cholesterol and no carbs.
