Genuinely interested to see tests results that back that up please?

I was once told the same thing, something along the lines of your body can only absorb 30grm of protein per hour, but I don't think thats proven.

As for Creatine, didn't do shit for me. Give it a try though, some people swear by it whereas others don't rate it. Depends if you have other things dialed in. Personally I think its all in the head, i.e. you think its working so you push harder. It could be a placebo but if you think it is the real thing I think the results would be the same.
