Review for: Double Rich Chocolate more...
I've only been working out for 5 weeks now and taking this product for 3 weeks. And I feel great.

First. The Gold Standard 100% Whey Double Chocolate tastes delicious. In milk it's just about as good as a chocolate milkshake. I have to resist the urge to drink more just for the enjoyment. In water it's not quite that good but still very tasty.

Second. I only take it right after workouts which are usually 8 pm - 10 pm after work. I'm up for another 2 to 3 hours afterward and I am getting no cravings where in the past late night was my worst time for eating snacks.

Third. After the first five weeks I've lost 12 lbs, feel great and look forward to the gym each day. I also so far, knock on wood, have not suffered from stomach pain or nausea in that time. I've felt the pain coming on twice at work after eating too much but after working out I've felt fine by the time I got home. In fact both times the feeling just faded unnoticed at some point during the workout. I'm still careful about what I eat but I have cautiously begun to allow myself more variety at lunch knowing I'd be heading to the gym later.

I am in love with the Gold Standard 100% Protein Whey! I love taking these after my workouts and early in the morning before class.  I do not take these with just water, I either drink it with milk or almond milk and it tastes delicious! 
I love how this brand has so many different flavors and the ones I've tasted so far are so delicious!  The powder is such great quality and I'm glad that this met my expectations.
I'd definitely recommend this protein whey!  I'll be buying again!

one of my favorite proteins I really love, the taste is super good and I saw results super fast, this protein I loved and tried several flavors and several proteins but it was the one that I liked the most, I recommend it with closed eyes, and the price is also good

Review for: Cookies N' Cream more...
This is a great high-quality protein, but the reason I love it so much is because it tastes so amazing.  The cookies'n'cream flavor is so bomb, that I dont mind drinking my protein shakes.  A lot of protein powders are healthy but taste disgusting, and I have to hold my nose and chug it down.  Not with this one, its delicious.

Review for: Chocolate Coconut more...
This is my favorite protein I’ve tried. I really like the consistency of the shake, it’s really creamy even when all I mix is water. I also find it pretty easy to mix in a blender bottle, it’s never chunky and tastes delicious!

Review for: French Vanilla Creme more...
This is my favorite protein powder. It is delicious and easy to use. I love that it comes with a scoop. I have tried countless other protein powders, but I always come back to this one. Like most workout supplements, it isn't too affordable, but it is worth it. I recommend buying this.

Review for: Extreme Milk Chocolate more...
Almond milk + This + Iced Coffee = Delish! 

I love pairing the milk chocolate with almond milk and coffee. Guilt free mocha and helps me hit my macros. Great little pick me up after the gym. The bananas and cream flavour is my second favorite, but not as good with coffee!

Review for: Vanilla Ice Cream more...
When I first started working out, I did so blindly. It wasn’t until I reached out to my athletic friend who told me that with the amount that I worked out, my muscles needed protein to build back up and highly recommended this. I was overwhelmed by flavor choice I have to say, whether it is long distance running or boxing or CrossFit, this protein powder is always waiting for me. I don’t think I’d switch to another brand anytime soon.

Review for: Double Rich Chocolate more...
One of my favorite proteins! As far as taste goes it is the BEST proteins I have ever tasted. If you use milk instead of water to mix it it honestly taste like chocolate milk. It isn't at all chalky and I look forward to taking it! Another thing I love is for the amount of calories it has it sure does pack a lot of protein and I'm all about getting my protein in. Has definitely helped me put on muscle but also a balanced diet is key. Only use as a supplement!

Review for: Delicious Strawberry more...
I don't know whether it was because of the flavor I bought but I don't understand why everyone likes ON's protein. I found it to be very grainy and it didn't mix well with either water, almond milk, yogurt and even in baking. Maybe I just got a bad batch, but I'm not a fan.
