John Berardi, a well-known and widely respected sports nutritionist recommends 0.8g/kg bodyweight of carbohydrate in a post-exercise drink plus 0.4g/kg in protein. If you weigh 90kg, that'd be roughly 70g carbs and 35g protein.
Some people may have more than this but from my experience this is about right, as if I have double this my insulin levels go sky-high (I feel very nauseas). This will contribute to perhaps a little bit of fat gain and the cortisol that is released as a result of a serious drop in blood sugar is anti-building muscle. So moderation is needed here.
Secondly it is believed that the quicker the ingested nutrients will be utilised the better, to reverse muscle breakdown etc. So this is why whey protein is commonly used with dextrose/corn maltodextrin: these digest quickly. Hydrolysed whey protein could well be the 'gold standard' of protein forms at this time - the theory is that it is already pre-digested by enzymes and therefore is utilised by the body even quicker than normal whey.
After this initial meal it is beneficial to keep taking in more meals of a similar macronutrient make-up, though with lower GI carbs if you are cutting, up to about 3 hours after exercise.
Some people like to put creatine in their PWO shake to make the most of the muscles' heightened receptiveness to nutrients at this time. Perhaps at this time due to the big insulin spike created by the carbs and protein, creatine mono would be almost on a level playing field with cee.
