Good product and size a little lump though. Not too bad

Incredible Product

It tastes so good, also very low amount of sugar. I definite recommend this product.

Lovely bit of kit

I bought this instead of the usual standard whey as I assumed it would be better, the taste is slightly bitter due to the lack of additives but you get over that very quickly. I use this in every day life as part of my breakfast in a smoothie and I feel a lot healthier for it. Also drink lots of water and take vitamin D and iron tablets you will be happier and work more efficiently.

No Nausea

I know it's expensive, but for what it's worth its the only protien shake I can drink alot of and not feel nausea. Slightly less so with chocolate, and the chocolate doesn't mix well. The others are fine.

Really nice taste

Received today (very quick delivery) tastes amazing and not thick texture , glad this doesn't taste chalky like the others, smells amazing , good value at £35 on sale

ON's reputation for excellence shines through with this product, and it's my go-to choice for post-workout recovery or a quick protein boost. If you want a high-quality, pure protein isolate that tastes great and supports your fitness goals, look no further than Gold Standard 100% Isolate Protein.

Like the flavour and it works as it says

High-Quality Protein That Delivers

Optimum Nutrition's Gold Standard 100% Isolate is one of the cleanest and most effective protein powders I've used. It mixes easily, tastes great (especially the Chocolate flavor), and doesn't cause any bloating. I've noticed faster recovery and better performance since using it. It's a bit pricier than regular whey, but the purity and results are worth it. Perfect for anyone serious about fitness and clean nutrition.
