20 grams.
Coupla interesting observations here. First, this gives us some guidance as to how much protein we should be consuming postworkout. That amount is 20g, which according to researchers is "sufficient to maximallystimulate MPS" after lifting. It suggests that anything more is beyond "maximal" levels.
Also interesting is that Torrent uses 20g of protein. The difference is that the study above used egg protein, whereas Torrent uses WPH, a much more efficient form of protein. So the 20g of WPH in Torrent should be more than enough (answering the many questions that people ask about whether or not Torrent has enough protein).
The study may also give us some ideas about that age old question--how much protein can I utilize in one sitting? Anyways, food for thought fellas.
