Given what it is, the flavor profile and range (energy, electrolytes and protein) I think this is a great product. The flavor might be a bit of an acquired taste. I for one love cotton candy although I can be a bit of a stickler on flavor accuracy. This tastes like cotton candy. It could easily be used in a multitude of recipes for smoothies or otherwise as well. This was my first time trying this brand or this product either one, It's a win for me. Not all caffeine is equal either, this is well rounded in my opinion. There is a slight aftertaste and a distinct chalkiness to it, but it is bearable. I recommend taking more than one sip when first trying this product and chilling it beforehand. Can't imagine this tastes good at room temp.

I was a little skeptical at first, but this cotton candy flavored protein water surprised me in the best way! The flavor is sweet and light—like a hint of cotton candy without being overpowering or too sugary. It feels refreshing instead of heavy, which makes it perfect after a workout or even as a mid-day pick-me-up. I also love that it gives me a boost of protein without the thickness of a shake. Sometimes I don’t want something creamy, and this is the perfect alternative. It’s smooth, easy to drink, and doesn’t leave a chalky aftertaste like some protein products do. If you’re someone who struggles to get enough protein in or just wants a fun, nostalgic flavor that doesn’t feel like “health food,” this is definitely worth trying. Sweet, refreshing, and functional—exactly what I was hoping for!

It’s really sweet, if you’re craving something sweet it’s nice though. It also has caffeine so great for the morning boost. Or pre workout. Very convenient protein on the go. Taste good if your into sweets. I gave 5 stars because it does taste good, just sweet. Still wish it was cheaper. No chalkiness, decent ingredients. Be aware IT HAS CAFFEINE!!!! Drank one at bed time not noticing the caffeine content stayed up all night.

Taste of product was somewhat off and made it less likely to consume them. However, one of the flavors was quite good (blueberry).

I tried this product because I had bariatric surgery and needed a certain amount of protein per day. This has been a great source of protein and energy, it has 20 grams of protein per bottle and only 90 calories per bottle. You can drink it on the run or before a workout. It comes in several flavors its not fizzy so it makes it very easy to swallow. Its not chalky and has no weird smell. What I also love is its gluten-free and lactose-free, no artificail sweetners and they use a green coffee bean to give you energy. If you dont want the energy then they have several other options as well. Its well worth the price and you can have the convenience to set up auto delivery to save more money. I drink this everday and do not get tired of it, it tastes great and the flavors are true to what they say. Highly recommend it for some great protein.

Protein 2o plus energy has been my go-to morning drink for years! It was a great combination of extra protein, caffeine, and good taste! Unfortunately, the formula was recently changed and now what used to be a low sodium drink contains 220 mg of added sodium, which is way too much for me. This might be the drink for you if you want those extra electrolytes, but I am searching for a new morning beverage that gives me protein plus caffeine without a bunch of additional sodium.

I love the protein content, the taste is good, you get your electrolytes, so a one two punch , it’s a bit pricey but will buy again , I bought the cotton candy and the variety, better than protein shakes any day!

I would say that this is the best protein drink I personally have had, just because I hate those vanilla/chocolate shakes. However, it is kind of hard for me to drink because its got a slightly weird texture. It's honestly kind of slimy. Besides the slimy feeling, the taste isn't overbearing which I like, and the fact that it's hydrating and has caffiene is a plus.
