You don't need to take whey immediately post workout. The 30mins/1 hour/2 hour PWO window is overrated and not as narrow as a lot of people think. It's an insane open garage door. Protein synthesis is still occurring within 24 hours. All you need is a solid well balanced meal post workout and TOGETHER with a protein shake on the side. I get amused when i see some youngsters running to the locker immediately and chugging down their protein shakes like it's a lifesaver. It just doesn't work that way.

last time my trainer told me to take within 30 mins after workout 

Follow what your trainer says. Simple. He's obviously moree qualified than the bros here.

We are just meatheads durrrrr we lift stuff and put them down.
