I'm no expert...
I'm no fitness expert but I bought this hoping that it would be something I could use at work on busy days when I cannot take a break. I am a hairdresser and I have long days on my feet and sometimes I don't get a break of any kind. I wanted something to hold me through my long days. I've now started using it in smoothies for meal replacements and after cardio and strength workouts and I really enjoy it. The taste is great. When I need it for sustained energy, it does what it says. When I want it for recovery, I notice a faster recovery time. I will keep buying this.

GNC associate said this would be good before bed or as a breakfast shake. I'm hungry an hour later (even a fruit smoothie lasts longer) and it does not taste good. I bought vanilla cereal milk and it reminds me of the old Slim Fast milkshakes.

I have tried A LOT of protein powders, just about every type you'd find in any supplement store, but this may be the best tasting one yet. It can help keep you on track with your diet by killing off cravings. Like Pro Jym, it has four different types of protein to release a larger amino profile over time, therefore leading to superior muscle recovery to a standard 100% whey, so performance is not an issue. I have come to learn that if a protein tastes good, you are more likely to take it consistently and I cannot emphasize the taste enough. You won't believe it until you try it!

To each their own
I decided to try this from my normal shake (the GNC Lean Shake Burn) to try something new. Honestly, I'm not too impressed. I feel like with in the first hour I'm starving again, where compared to the other I was full for hours. The flavor (peanut butter) is okay. I found to mix it with my morning coffee and then put it over ice is by far the best. I think the fact that this lacks caffeine is my biggest issue. But I would not tell people to not try this. Big fan of GNC products. Just not my favorite.

Love it
I love the flavor. Taste just like fruity pebbles and no protein taste..AT ALL! I have let several people try it and they all love it.

Pretty Good
While I don't believe that the process takes 7 hours, I do think the added blend with casein does help curve my appetite a bit, and I don't feel as depleted going to the gym. My issue was eating enough going into the gym, I can drink this 2 hours or so before a workout and still feel like I have something on my stomach to push thru my routine. The taste in on par with other decent tasting proteins. Working well for me, try it for yourself see if you like it.

My favorite!
The best protein I ever had!! I lost weight and I feel like it doesn’t make me feel bloated!

10/10 would reccomend!
BY FAR THE BEST TASTING PROTEIN INHAVE USED! (I got the vanilla cereal milk) I lalso ove that this has both whey and casein protein as well as BCAA in it. Perfect for breakfast if I'm in a hurry, or cramming in that last minute protein before bed if I'm short for the day.

Why does everyone talk about taste and not performance?
I am on my first tub (chocolate - tastes just fine and dissolves into 1% milk and almond milk and water blend just fine) and only one in 12 reviews comes close to discussing performance benefits or anything remotely close to bloat, recovery, muscle growth, etc. I'm glad you are reminded of Saturday mornings and cartoons growing up - how about a real review? So far I have noticed no bloated feeling but it is too early to discuss the tangible results. Stay tuned.

What is best liquid to mix protein blend with?
A shopper on Mar 4, 2018
Do you need to work out if you are taking this?
A shopper on Feb 28, 2018
BEST ANSWER: No, essentially a serving of this protein would be comparable to eating a piece of chicken. However, if you do work out, it would improve muscle recovery and can assist with increasing muscle mass.
Which BCAA's are in this product?
Antonio on Mar 20, 2018
BEST ANSWER: BCAA's always refer to the three amino acids known as Leucine, Iso-leucine, and Valine. This protein blend has 5g of naturally occuring bcaas. All this means is that there are none added but that the protein itself has bcaas in it.
Can teenagers use this product?
A shopper on Feb 20, 2018
BEST ANSWER: Most certainly. 17 is the prime age! I. Fact no stopping me at any age :)
Are there any opinions on the fruity crisp flavor?
3stripe on May 15, 2018
BEST ANSWER: It tastes like the milk after you eat a bowl of fruity pebbles. I would recommend the cinnamon toast. I thought it was the better of the 2.
Can i take more than one scoop?
A shopper on Feb 21, 2018
BEST ANSWER: You can take 1 scoop per 8-10 ounces of liquid. I've done 2 scoops in a 28 oz shaker cup and it tasted fine.
