I agree with jason.
Normally for a post workout a ratio of 5/3 is recommanded.
for 5g of carbs you ll take 3 g of protein.
After all will depend of your goals if you want to gain weight the maximum of protein recommanded is 2g/kg/day
so if you are 80 kg ( sorry guys I’m not good with lb , but the ratio is the more important) you’ll take 160g of protein per day. don’t forget the protein in your meals , shaker are just add one!
