NOW has unflavored protein produced in a GMP-certified facility. You can also buy protein powder directly from dairy farms, which is helpful when there's a shortage/price-spike - I've bought from Dana farms. It's also significantly more fresh and tasteless. Buying from Dana Farms you can either buy it with a small amount of emulsifier to help it dissolve in water or just single-ingredient pure without that. If purity is particularly important to you I'd recommend "isolate" over "concentrate", it will have even lower amounts of lactose, which can benefit people who are severely lactose-intolerant.
