Nutrija isolate protein are the best isolate in the price range, I am using Nutrija Isolate 95 & 90 for past 1 year. Quality is far more better than any other brands in the range between 1.8k to 2.5k. Quality is top class. I would request Nutrija to maintain the same quality, but would also request them to keep an eye on the price hike during last 4_5months for all of their products
