If I take two protein shakes with double servings I am not halfway to my daily goal, but sure it helps! I tend to have protein powder and greek yogurt for breakfast (with peanut butter) and a double serving after the gym. That, with a protein dense lunch and dinner gets me to around 180g protein.

it's less than you'd hope. you need a fairly high volume of protein shake to get more than 40g of it in a sitting, and your target is probably like 100 or more grams of protein a day

I did a daily shake for a while as an after gym recovery food and I still had more calories from carbs than protein. it's just difficult.
