The 5 lb tub and 24 g scoop are why this is the one we reach for first. It is a whey isolate and concentrate blend, so you get a complete protein with 5.5 g of BCAAs and 11 g of EAAs per scoop. That matters less on a label than in the shaker: it mixed clean for us in water and milk, with no gritty finish, and the vanilla is creamy rather than thin. The flavor is sweeter than some vanilla ice creams, though, so chocolate is the safer choice if you want less dessert.
We paid attention to digestibility because a daily powder has to be easy on the stomach, not just high in protein. This is still a whey product, and it can cause bloating for people who are sensitive to lactose or whey concentrate. If that is you, an isolate is the better route. For everyone else, the 5 lb size is the practical part: it is a staple tub, not a sample, and the scoop is easy to level.
The vanilla flavor is the one place we hesitate. It is pleasant, but it does not read as vanilla ice cream to us; it leans sweet and slightly artificial. The chocolate flavors have a better reputation in our own rotation, and the neutral profile takes fruit and peanut butter well. If you want a flavor that disappears into a smoothie, this is still a strong choice.
Pros
- 24 g protein with 5.5 g BCAAs and 11 g EAAs
- Mixes clean in water or milk
- 5 lb tub suits regular use
- Banned-substance tested
Cons
- Large tub commits you to one flavor
Our default for a daily shake: 24 g of protein per scoop, reliable mixing, and a 5 lb tub that suits a household.
