Best protein supplement!
The watermelon is the best flavor if you drink it straight out of the bottle, this has been the most simple and effective way to add extra protein to my diet, I always struggled with being able to eat enough and with proteinx I get all the protein with none of the volume that food and shakes have, I’m so impressed with this product, it’s amazing for bodybuilding and protein supplementation, the consistency is so hard to describe it’s like highly drinkable honey that’s thinner than normal, super easy to just gulp down without a lingering aftertaste.

Know how to use it and you'll get good results
Okay. So I originally ordered the cherry flavor in hopes that it would taste like idk .... Those fruit punch juices? I was wrong. The cherry flavor is very medicinal-like and I HATE IT. I contacted Amazon support and they refunded me the $ so I could order a replacement. I decided to go with the watermelon flavor as I figured the grape would also be medicinal-like (I remembered medicine I used to take as a kid that was grape flavor, yuck). Let me tell you how I use this product to make it taste and easy to digest: (1) I use sparkling soda or sparkling water to trick my brain into thinking I'm drinking a yummy soda (diet coke connoisseur here🙋🏻♀️). The flavors I have tried are strawberry lemonade sparkling soda and plain sparkling water. With the Cherry flavor I originally got of this product, it was too much with the strawberry lemonade sparkling soda but again, I was doing two tablespoons. I think trying one tablespoon earlier in the day and the other tablespoon in another cup of sparkling soda later in the day will help with the medicine-like flavor. So with the cherry flavor, the plain sparkling water was the best for me personally. (2) I have decided to split the serving size into two. One tablespoon in one cup of sparkling soda during lunch and the other table spoon in another cup of sparkling soda during dinner. The watermelon flavor is quite delicious with plain sparkling water whether it's one tablespoon or two though it can be too sweet for many so I advise doing one tablespoon per cup of sparkling soda/water. That's it! It desolves nicely in sparkling soda/water though I noticed that when I did the full serving size in one cup of sparkling soda/water, the carbonation of the soda kind of went away?? Like, the "sparkling" part of the soda just turned flat, like a soda that's left open for too long or after all the ice is melted so again, I advise splitting the serving size into two to prevent this from happening if you really value the "sparkling" part of soda. Overall, the watermelon flavor and sparkling soda/water technique combination is a 10/10 for me.

Quite Tasty for a Protein Supplement
I first ordered the Pina Colada and yes is had a pretty nasty smell BUT mixed it with some club soda, it was quite delicious. It leans in heavier to the coconut but over all has a great flavor. 2 days later, decided to give the watermelon a try a found that to be quite tasty as well All that to say that yes, neither smell nice and both do have a clear vitaminy taste but it didn’t bother me and would be easily hidden if you mixed it into a juice or other flavored drink mix. All in, I’m totally delighted and am looking forward to trying the Lemonade when it’s back in stock

It's way too sweet… but it’s the best of it’s kind
I came here to change my original review. I said “It’s like super sweet cough syrup but worse. I even tried adding it to water to dilute but that didn’t help. It just made me suffer longer. “ And that is true. HOWEVER, I've tried other similar products from other brands, and now I know why they made it so sweet. Turns out plain protein in liquid is absolutely vile. Which, I probably should have guessed. So yes, i will gladly and happily digest two tablespoons of sweet, flavored cough syrup instead. Amazing product. I will buy this over and over again.

Tastes like fisherman warf
This tasted absolutely disgusting. I use a watermelon strawberry hydration powder, so I thought hey what a great way to get some added protein just throw a little watermelon in there. This was a really bad decision. It literally tastes like fish. And it wasn’t even just a little subtle. This was full blown marine, collagen fish. Marine collagen is a flavor that you are used to and you are OK with this would be a fantastic product for you. I simply cannot add fish flavoring to my water.

Taste profile: fake watermelon with a touch of cow hide.
Tastes horrid - helps with protein intake tho. I have a hard time getting my protein in and I can’t stand to chug protein shakes constantly. This helps in a “ripping off the band aid”- kind of way. I hold my nose and drink a small cup of water with a cap full of the collagen protein. The taste I would describe as “fake watermelon with a touch of cow hide”. If I mix it in a large glass of water, I add lots of ice and lime juice, to help with the flavor. It is also sickly sweet. I’m gonna buy it again though, cause it makes me getting towards my protein goals easier!

Thick like honey, but tasty and packed full of protein
Why is it so thick? I got the watermelon flavor. It tastes fine, but yeah, it’s surprisingly thick. It’s as thick as honey. Regardless of how thick it is, it is a super easy way to inject more protein into my diet. I try to hit my macros eating whole foods, but just can’t manage to hit my protein targets on food alone without pushing me over on fats and carbs. This adds more variety into my alternative protein options. I’ll definitely buy again.
