The Best Flavours!

Review by Bradley on May 19, 2022
Great product, really does the trick. I have mine mixed with milk and you wouldn’t even know it was protein powder it had mixed with!

Glad I purchased this!

Review by Anonymous on May 17, 2022
I bought the unflavored whey protein hoping that it wouldn't detract from the flavor of the smoothies that I make every morning...and it doesn't! This powder dissolves well in my shake and I love the fact that it is 100% whey. I am very happy with my purchase and will be buying again.


Review by John Gray on May 16, 2022
This is, by far, the best tasting protein mix I've ever had. Everything else I've tried tasted chalky and too artificial. Optimum is so much more flavorful. Great job to the researchers on this product.

nice flavor

Review by mari on May 16, 2022
I normally get the chocolate and vanilla flavor but I got really tired of the taste and decided to step out of my comfort zone and get the strawberry flavored one. I was worried it would be too strong and overly sweet but it actually has a very nice subtle strawberry taste. Sometimes I will blend it with a few frozen strawberries (not fresh or else it gets foamy) and it makes it taste even more like strawberry.

Tasty (strawberry), quickly solving and has a good quality.

Rocky Road review

Review by JZ on May 13, 2022
Flavor is pretty good, doesn't come off fake at all. This particular flavor mixes really well, which can be challenging for the flavors with a lot of chocolate in them. Overall a solid protein supplement.

Chocolate malt tastes great

Review by Michael on May 11, 2022

Whey protein

Review by Syed on May 8, 2022
Great product, loved the taste.

Doesn't taste great but does what I need it to.

Review by Bob on May 8, 2022
Landed on Gold Standard as a good / reputable brand to buy whey protein from and I bought the Vanilla Ice Cream and Chocolate Peanut Butter flavors. So far I've mostly been mixing the Vanilla one into some fruit smoothies to add some protein into them and it's been ok. Tastes maybe a bit chalky but adding ~25g of protein to my smoothies is what I was looking to do. The chocolate peanut butter one I'm not a big fan of. I saw a lot of reviews and comments online saying to stick with the chocolate based flavors and that one I just flat out don't like and won't buy again. It tastes way too artificial and not close enough to chocolate and peanut butter. It also really lacks the flavor of peanut butter if you ask me. Like the title of my review says, I just needed to add more protein into my diet as I've been getting back in the gym more often so for me it's much more about the protein than the flavor but in the future I think I'm more likely to stick with vanilla based flavors.

Good product

Review by Damien on May 6, 2022
I like the taste, I choosed chocolate and peanut. It dissolve well. I tested differente protein and this one is among the best. Do not hesitate, it's a good choice.
