It's too early to determine the products efficacy, but the taste is incredibly awful...I mix it with orange juice and powdered vitamin C to help kill the taste and gag it down as fast as possible. The smell is like cow hoofs...I would recommend the chocolate flavor.

First time taking a collagen and wow, smells horrible and taste lingers. I mix mine with orange juice and it’s manageable. But I am seeking benefits not taste and smell. Product works great. Ive been using it for 2 weeks now and I swear by this stuff. I applauded MyProtein on a great product. if your seeking benefits I would definitely recommend this product.

I usually stick to my favorite collagen. Over the last few years I've only ran into one other collagen that was as bad as this one. I went against my better judgment and ignored the bad reviews, I wish I hadn't. The smell I can look past, the taste I can't. I would hope they would listen to the bad reviews and pull this product, even if it's going to cost money. Glad I caught it at half off.

No idea and I'm not going to try and find out.

I use it every day! What people are expecting from dead cow skin? This is collagen with nothing else added. It smell and taste what it is! I make my morning shake half and half with vanilla protein and I add a few drops of "flavdrop", unsweeted cashew milk and ice. Taste really good!

The unflavored collagen smells like a combination of dog food factory and cow pen at the county fair. The bad news is that it tastes even worse! If you mix a 1/3 portion of the collagen with a lot of Gatorade, and then hold your nose while drinking, you can get through the experience. However, as soon as you start breathing again the taste lingers in your mouth and you will be tempted to cut off your tongue! I don't know about the chocolate collagen, but there are no words that properly describe how awful the unflavored version is. I can't believe that MP hasn't removed this product from its sales line-up.

Any drug or illness that completely eliminates one's sense of taste and smell!

This product is absolutely horrible! It literally smells like a rotting animal. As soon as I opened the bag it stunk up my whole kitchen. Good luck even getting past the smell to taste it. Complete waste of money.

The garbage can

I tried to mix with my home made jus which are mix with mango lemon celery and beet, the result was surprisingly good.

I was really looking forward to adding this to the mix of products I get from myprotein. Unfortunately, it has a really fowl smell when you open the bag and the powder was moist. I mixed in some stevia and mocha flavor drops, but it did not help. The bag went into the trash this morning.

I think the best description from another review was "smells like a dead cow". By far the worst smelling collagen I have tried. And the additional bonus was I spent 40 min. throwing up in the bathroom after taking it. Then customer service had the audacity to ask for a doctor's note if the problem continued. As it I would ever try this or any other product from this company again.

Throwing up in the bathroom.

This was probably the WORST smelling collagen protein I have ever encountered in my life. I have used many different brands, but I figured I would give this one a shot since I love a lot of the My Protein products. Initially when I opened the package it had an odd smell, but most collagen proteins have a smell to them. I put a scoop down in my coffee cup and started to pour my coffee over the power, and the smell of rotten garbage hit me. It was so bad I couldn't handle it, and it made my whole kitchen smell like garbage, I took the bag and immediately threw it in the trash. I would not recommend this to anyone, extremely disappointed in this product.
