Optimum Nutrition (ON) Gold Standard 100% Whey Protein Powder - 5 lbs, 2.27 kg (Vanilla Ice Cream), Primary Source Isolate (Packaging May Vary)

I love all the products from ON. The vanilla was not so good though as per my taste when compared to other ON flavours. I have tried a number of brands with a number of flavors. The taste wasn't that good but the results were amazing. This was an authentic ON product.

Vanilla flavour is really good Not sure about the efficiency of the protein though doesn't stand out form other competitors by any specific way

The product doesn’t have any authentication seal and when contacted with Amazon they are passing the buck asking to contact the manufacturer. We r buying from Amazon for the ease and trust in products.. now they are like we can’t do anything abt it. What happened to the 10 day return policy ?? This is absolutely not done.

100 percentage sure its fake. No seal and fake powder

A good product

I went ahead and purchased the tub despite a few negative reviews. I was very particular about the quality and can confirm that this authentic ON protein supplement. While the price is high, I wouldn't want to compromise on the intake of nutrition by taking that is sub standard or below par from a quality standpoint. The protein mixes well with water without any lumps and there is enough aeration in the tub to ensure that it doesn't get spoilt. You may purchase this without any hesitation. The flavour too is decent.

This is my second order of the same product. The first time around everything was fine & perfect. However, this time something is really off! The product was checked and it was found to be genuine on the website. However, there is a strong after taste that kind of makes my mouth feel weird. The smell is fine but the consistency of the powder is also too grainy. For some reason it feels not an original product and I’m worried when I’m having it.

I don't know what its doing to my body, I only took it for one week, my friend said it works quickly even I'll feel the extra strength! God knows when it will work btw I'm very skinny and working out regularly, if it really does any good to me and I realize then I'll update the review.And for those queries if its genuine or not there a link on Optimum Nutrition's page where you'll see authorized importers as its not made in India,Primarc pecan or something like that, you can buy from this seller on Amazon. But I got it from cloudtail and it has the sealed paper mentioning imported by primarc pecan, just add it to your wishlist and check sellers available for it, one day hopefully you might see cloudtail is offering it !!!Packaging was kinda weird,there was just one box outside of it.Taste is not good, I try to mix it with milk then drink . And really lactose intolerant people should despise it. For the first few days after taking it, I felt uncomfortable in my digestive system! Whatever now I kinda accustomed to it.
