Its all rubbish. Yes, I buy protein supplement for the simple reason of getting my protein intake at the right levels and since I am 105kg that's a lot of protein. I don't work so I am cash poor so I don't have the money to buy a lot of food so I pay $1 for a 35gram serve of protein and a chicken breast cost $10. I do eat a lot and the supp just adds to it. My friend owns a supp shop and also has his own line of supps. I asked him all about it and he said this: there is no magic protein plant or cow and we get the protein all from the same place. Its all the additives that make the difference and most of them you don't need so buy a cheap protein for the purpose of adding to your food intake. I have a lot of friends from prison that are fucking giants and they don't get $100 buckets of wpi in prison so don't waste your money. Spend it on testosterone and dianabol instead and watch yourself grow...
