For starters, Optimum is one of the best brands around, so I'm very happy to say that this is another quality product from them. I bought this as an alternative to the regular 100% Whey because my parents are EXTREMELY concious about the supplements I take and consider something like Jack3d to be a steroid (...parents...). Anyway, I really liked the regular whey so when I made the switch to natural, I was pleasantly surprised because it tastes BETTER than the regular whey (I had the chocolate flavor). The Stevia that they use to sweeten this product is one of the healthiest sweeteners around, and I also like that they added an Aminogen complex to help with digestion. It's very low carb so it fits in perfect with my CKD diet. I usually take 2 servings a day, 1 for a postworkout shake and 1 to use in various ways, whether it be with my breakfast, lunch, a snack, in a homemade protein bar, or after basketball conditioning. It's very versatile and "clean". The recovery from it is pretty good considering that I'm not as sore as I used to be after working out. It's also relatively cheap ($22/29 servings). The only quams I have with this product is that there's no "extras" like glutamine, creatine, CLA, etc. in it. It's also not a blend, which makes it unusable at nightime. For these reasons, I'm most likely going to make the switch to Optimum's new Natural Pro Complex, but it's hella expensive. So, until then, I'll still be taking my trusty Natty Whey. The key with this is to be patient, take it religiously and the gains will come. Don't think it'll work like a PH or anything, but if your patient, you will lean out.

I have tried other whey proteins and this is by far the best tasting and I believe the most effective based on ingredients.

Ingredients: 10/10- This product has a nice mixture of whey isolates, concentrates and peptides. Each scoop has 24G of protein, 4G of carbs, and only 1G of fat making it a good product for a bulk or a lean cut.This protein also has a nice amount of essential , non-essential and branched chained amino acids. It contains 5G of BCAA's and 4G of glutamine.

Price: 9/10- For the quality of protein you are getting you can not beat the price. I picked up a 5lb tub for $52.99 on BB.com which I feel you get what you pay for and this is a good product.

Taste: 8/10- I have tried the peanut butter, which I felt was exceptional. I have also tried the cookies and cream which is also I would say a not bad tasting product. This product comes in quite an impressive amount of flavors. You are sure to find one that you like.

Effectiveness: 10/10- I feel it is hard to judge the effectiveness of a protein because it is a contributing factor to your recovery, bulk and muscle building.It is not the lone factor. This is a product that I have made a staple in my stack because I have not been disappointed. This product has been legendary for some time now and I think it's reputation speaks for itself.

Overall: 10/10- If you are looking for a good whey protein for your stack you can not go wrong here. Personally, I like the fact that it is low in carbs and fat for trying to build lean muscle, which is what I am doing right now. This is a protein that is good for a pre-workout or a post-workout drink. I personally drink it pre and post with a casein before bed. I have suffered no side effects with this protein. I have had whey proteins in the past give me gas but this one does not.

I was using another whey protein before and the supplement store I get my stuff from stopped selling the stuff so the owner recommended this protein. It was a little more expensive but definitely worth it. It really mixes easily and the taste is good. Not too sweet and not too strong a taste or after taste which I like. No GI distress with this stuff. Just take it and grow!

Optimum Nutrition's 100% Gold Standard Whey Protein is the BEST protein I've EVER had. There is no going back once you have tasted it. I first started weight lifting, then went through two rounds of p90X before going on to INSANITY! This protein is the quickest and best mixing protein there is, even in water. It has the standard amount of protein per serving and it tastes amazing. I've tried 4 different flavors and all have been great. For as great as it is, it's also not overpriced, easily affordable if you are looking at "value-for-the-dollar". It is a great addition to anybody's stack if you ask me. In it's isolate form you are sure to grow your muscles with this protein.

RESULTS: Unparalleled. Excellent gains in overall frame, strength and appearance. I'm definitely noticing the results compared to when I was a newbie who worked out absent any protein supplementation.

SIDE EFFECTS: None

TASTE: Depends on flavor...Strawberry banana is absolutely dreadful. Cookies and Cream is DELICIOUS. Double Rich Chocolate is pretty delightful too. I rotate between C&C and Chocolate.

I've sifted through about 8 tubs of this protein now, and I don't foresee myself switching in the near future.

So I think everyone is aware of the fantastic quality of Optimum proteins so I don't need to re-hash that. The most surprising feature of this product is the TEXTURE! It is smooth as velvet when mixed in a blender. It's not heavy or chalky at all. Also the taste is very nice, I'd say the Vanilla is right up there with Syntha-6. But with far fewer undesirable ingredients. A solid protein for a decent price.

Solid protein product here.
Taste is great. Was clumpy though when mixed.
I think the best part is the natural ingredients in it. The sweetener is RebA and that is a stevia derivative.
Overall if you are looking for a decent, all-natural, great-tasting whey..Optimum is the Whey to go :)

So one day while browsing proteins at my local supplement store, I come across this and think, "hey, I take a lot of supplements with artifical sweetners, it would be nice if at least my whey didn't have any". So I purchase the ON Natural Whey in chocolate. Now, I am not a big 'taste guy'. I don't take these supplements for the taste. In fact, I kind of sneer at the people who won't take something because it doesn't taste like a baskin-robbins shake. But this stuff here is where I have to draw the line. The taste is almost equisitely putrid. the only reason it gets a 4 is because with skim milk, i can get it down. With water, forget it...it tastes like vaguely chocolate flavored body sweat. I'm not going to waste time saying anything about the product..everyone knows what ON Whey is about. Just be warned, from the most non-descriminating supp user ever, the natural version is very, very tough to take down.

I have been on and off various proteins over the years. This one is by far the best tasting (vanilla). As far as the results, too soon to tell but the other reviews are good. I will post more detail when I complete the product.

I have the strawberry flavor.This has alot of citric acid and is kinda hard to mix and is getting very foamy.
No ace-k or sucralose and that's great ! :D
I will soon replace this with Natural Oats & Whey.
