Could someone tell me which is the best Protein shake for weight loss?(Please read details)?

Could someone tell me which is the best Protein shake for weight loss? I've already bought three so far and they're not cheap. I bought Amazing Gr, Biochem Sports 100% Greens and Whey and Living Harvest Hemp Protein. Keep in mind that I am working out, about 4 days a week. I don't expect to loose weight by dietary supplements alone. I would really like to find a protein shake that has a appetite suppressant in it like Hoodia because after I work out, I just want to eat everything in the house.
