Query: Worst Protein Powder Ever

I am a long time Amazon Prime user who has never reviewed a product, that is until now. I bought this product to try to break up the monotony of chocolate and vanilla so I was very excited to try it. My excitement was short lived however because from the moment this "stuff" touched my lips I wanted to vomit. It has the worst metallic and bitter flavor. Only on Fear Factor would this be considered refreshing. I finished the whole tub but it took me 3 months to do it and I pinched my nose the who way. RUN do not walk from this product, you'll thank me for it. I want to suggest other products to try but I dont want anyone thinking I had alterior motives for this review. PLEASE heed my warning and go elsewhere for protein.
