Love this product. Not heavy at all and doesn't give you that bloated feeling a lot of protein powders give. I've been having it in my daily smoothies and ive lost 9KGs, its the only part of my diet and exercise routine that ive changed so its definitely works well as a part of a balanced diet. Very smooth, dissolves easily and doesn't leave a milky taste. Vanilla is definitely my favorite and goes with everything - unfortunately it was out of stock so had to try the chocolate, took a while to get used to the taste but otherwise great as well. Definitely recommend.

Miracle product!it's a great product. it mainly contains whey isolate unlike other proteins that contain concentrated whey. Rich in amino acids and branched amino acids, it provides a high protein level with a low carbohydrate and lipid content protein.tnI highly recommend !

Better than 5 stars

Ignore the 3 star review. Are there “cleaner” proteins out there, yes. Does this one have a couple more ingredients than them, probably. Does that matter to you?… Decide then buy what you want.This is probably the best chocolate protein I’ve had in the 20 years of drinking different powders. Mixed alone in water it’s delicious. Make a full on “shake”…fuggetaboutit.Mixes great.Above all the other praises; for myself and many clients I’ve recommended this to, none have experienced any gastrointestinal distress common with people with milk protein sensitivity. This is a result of an obvious high quality level of “isolation” of the whey protein.Try it and you’ll understand why it’s always out of stock.

Good profile, too sweet
29 July 2021

Based on my experience alone: the protein powder is so sweet that I need about 600ml (20 oz) of water to dilute it down to something drinkable. Diluted, it tastes alright, and the nutrient profile is also good.For some reason I get extra hyped after I drink it, I don't know whether it's because of the strong sweetness, the fact that I've switched from regular Whey to Isolate, or something else. Either way, I don't think I'll buy this specific brand again.Update: for the second time I tried it, I get nauseated, won't use this brand again.

Great post-workout product
22 August 2021

Overall great product. I find it a bit too sweet to drink mixed in only water (it tastes like melted vanilla ice cream), however, I mix it in water and then add it to my greek yoghurt & berry smoothie. It dissolves well in water if you stir it and leave it for about a minute- before drinking or mixing it in a smoothie. I much prefer the isolate to whey, as it is much easier on one's stomach. Furthermore, the product does what I want it to do- it assists with post-workout muscle support and hitting my macro targets. Overall great product.

Hidden Gem on the market. This is truly great.
22 May 2020

This is a hidden gem, a true hidden gem. In fact, it seems like the whole Gold Standard 100% Isolate series is. It's great. Minty, just the right amount of sweetness, and a very subtle, almost UNnoticeable artificial taste of sweeteners at the end. The chocolate flavour is a little subtle, so take half a scoop of this, half a scoop of Double Rich Chocolate and it's perfect. I wish that I bought more of this. Also, by itself, it tastes better with water than with milk for me. Milk makes the chocolate flavour noticeable, but water preserves it. if you blend it with Double Rich Chocolate, add half milk, half water. It's the best thing in the world.

No Reason to Try Anything Else
12 August 2021

This is the first protein supplement I've tried and am unlikely to try anything else. I like the versatility of the product and results I am experiencing. I purchased the Vanilla and use it in multiple ways- shaken with milk for my cereal in the morning, shaken with oat or macadamia milk for a quick drink, and added to my fruit smoothies. My boyfriend says it tastes like marshmallows. Along with the great taste, I am finding that this product helps me with progressive overload. My muscles are able to push it a little more since I've started using this regularly.

Outstanding Product At A Reasonable Price
4 December 2022

This is an outstanding product at a reasonable price. This product enables me to achieve my optimum daily protein intake (100g) without exceeding my target calorie intake (2,000 calories). It is also very economical because a 4-lb. tub lasts almost two months, less than a dollar per day.

Wierd aftertaste
10 November 2018

I purchase this direct from ON in the Strawberry cream flavor. I mixed it with 8oz of water in my shaker cup and noticed it failed to mix well leaving clumps in the drink. The initial taste was ok, but the aftertaste was very chemically. The second time I mixed it I used almond milk and a personal blender. This resolved the clumping issue, and it did taste better with the almond milk, yet still had the same strange after taste. The third time I used whole milk and the blender. This was actually the best way to mix this particular powder. Still, it had a strange aftertaste to it, albeit not as noticeable as in previous variations. I did use the entire container switching between this and two other brands. I was glad when I finished the tub and would not consider ... MoreI purchase this direct from ON in the Strawberry cream flavor.

I was glad when I finished the tub and would not consider buying this again, especially in the strawberry cream flavor. I will admit that about halfway through the tub I started to crave the taste of this. I am not sure if it was due to the chemical sweeteners or what it was. However, I will pass on this brand in the future and go back to the other two brands that are all natural.

oh my stomach
26 November 2022

Bought this to help me get more protein in since beef and chicken prices are sky high. Thought this would really help me out. My diet is pretty plan. potatoes, rice, oats, eggs, chicken, been, veggies, fruit, and water. Thats it. Im not going to lie this stuff had me rushing to the bathroom quick. after the 2nd day i cant take it any more. Extremely disapointed because i spen $60 on it. So if you follow a strict diet with no artificial sweetners, or processed food BEWARE. Its like a rumble of a cannon, flip the lip up, sit, and fire.
