Just found that but don't know how legit it is
.But you guys know you don't need all these over-priced crappy protein shakes and bars etc, right? You can get all you need from a well-balanced diet or just upping your protein intake by eating good protein-rich foods. Much cheaper and tastier than these crappy shakes.
Actually, you are wrong. Protein shakes (whey) are CHEAPER than meat, fish, chicken, etc.
Well, at least in my country. And that's the main reason I use protein shakes.. together with food.
100 g protein from whey: $2.5
100 g protein from chicken: $8
100 g protein from milk: $4
100 g protein from salmon: $13
. But doan be disappointed, most people do not even think to listen until the next big player joins.
