I've seen several articles proclaiming "you can only absorb 30/40 g of protein per meal/hour" to be a myth, but none of them that I have seen have provided an actual helpful guide to go by.

Has there been any research done to actually determine how much protein one can absorb? What do you all use? I usually don't go above 50 per meal, but I have no idea if I can go higher or if that is too high.
