It is a good protein and I have used it on and off for years. It mixes well, is naturally flavored, and is very reasonably priced. The only criticism I have is that the taste is only so so. I prefer a little bit more chocolatey flavored*

I've been using this protein powder for a long time. I like the vanilla flavor. It does not do well in the microwave like in oatmeal.*

Mixes well and I like that is does not have artificial sweeteners. The taste is excellent i usually use some almond milk with it.
I have been able,to,loose a few pounds of fats and then put back on muscle using this protein powder. I just ordered the 4.8 lbs of Chocolate , vanilla and strawberry. I use it cooking as well.*

Quality and Results: I do not feel bloated after using this whey. I am really satisfied with the quality and results while using this casein. It is a bit more expensive than other whey-based products from Optimum Nutrition or even other brands. However, it is naturally flavored, which makes it better than other artificially flavored proteins.
Flavor: Chocolate flavor tastes great.*

100% natural- it doesn’t get much better than that. This is the first protein powder I bought when I started working out in middle school. I graduate college this year and am still using the same powder. Trusted ingredients, trusted manufacturer, and quality results. *

Here is my new sludge recipe: about 40-45g of frozen berries left in a cup for about an hour to defrost, then put in a scoop of casein and gradually add milk (if bulking) or water (if cutting) stirring it to a desired consistence. Put into a freezer for 30 minutes.*

Ah, and one more tip: It definitely better dilutes in room temperature milk. I normally put milk into a blender 2-3 hours before workout and leave it outside or a fridge but if you forgot to do so and you have a milk directly from a fridge shake REALLY HARD while blendind and you'll be fine.*

I had the chocolate whey and it was great. Also have the french vanilla casein and it was really good. Thats why I don't get why this vanilla protein tastes so ungodly bad. If I could get my money back I would. ON needs to get taste testers or some kind of focus groups. This product is unacceptable.**

Last time I've accidentally ordered a not naturally flavoured (red label) one and have realized how much naturally flavoured is better. Not too sweet, larger powder grain (not sprayed around the kitchen when applied) and no palm oil (in protein? what for?). Definitely will stick to naturally flavoured one.**

Just started with it so I can not judge an effect but at least chocolate taste is absolutely fine, same as a cool cocoa drink you will get from a grocery. Dilution is almost instant.*
