Bests & Worsts Reviews from Amazon

I have purchased unflavored Genepro protein powder a few times for after bariatric sleeve surgery. I had heard about it not being 30 grams per scoop as it claims. My son is a pharmacist and I asked him to check into it. He did and told me that it actually is only 10 grams of protein per scoop. I can't believe that Amazon would sell a product with such blatant false advertising. I'm really upset that I've not been getting the amount of protein that I'm supposed to be getting daily because of the false advertising on the package. It's unethical advertising. I hope my health hasn't been compromised because I trusted the product and Amazon.
