Bests & Worsts Reviews from Amazon

I'm a fan of Isopure but I question the authenticity of this product. Nothing was similar to the product I buy @ Vitamin Shoppe. I usually can mix this with a spoon & drink with water but this was clumpy & bland. The seal wasn't on the container & I didn't get the usual servings from the tub. Update: This is the second time I've bought Isopure on Amazon & will also be the last time. The seal was not on the lid & the seal that's under the lid was not on the container either. The quality of the protein is not consistent with the ones I've bought from Vitamin Shoppe. It doesn't mix well & gets sticky instead of dissolving. I once again question if this is the same powder.
