Supplemental Protein
Purchased 2 flavors of this Sustained Protein Blend to supplement the Amp Wheybolic Ripped that I take pre-workout. Post work out I take Vanilla Cereal Milk & put in a Nutribullet with frozen strawberries & plain kefir-delicious like a strawberry milkshake. I exercise late at night so this mixed with kefir-the champagne of milk which also has a high protein content is great to get me through the night with a positive protein balance while sleeping. First thing in the morning I take chocolate cereal milk with plain kefir-good but my fav is the post workout with frozen strawberries blended, This works for me-a female 4ft 11in tall & 64 but leg press 798# max-guys at the gym all freak out.

Keto diet friendly
My husband bought the peanut crisp flavor and I was instantly jealous. I do keto diet to cut weight when I get heavy and wanted to try it. My mind was blown that it had only 3 carbs. I didn’t hate the flavor just not crazy about peanut butter. We went and bought my own- fruity crisp. I love it. I use it less than once a week but it is so nice to have another option for breakfast. I find that if I drink this I am not hungry till dinner! I have to remember to eat! I also love that it gives me the chance to “taste” cearel again as it has too many carbs for the keto diet. It takes away that cearel craving!

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.

Taste and performance
First and foremost taste is on point I tried the fruit charms and the cinnamon toast and I’m totally blown away on how good it is with just water and a couple of ice cubes. Secondly performance I use this shake as a post work out recovery drink after hitting my crossfit classes. Keep in mind Suppliments don’t work unless you do! Recovery is amazing and the added casein protein helps with night time recovery too. I would recommend this to any serious athlete or someone looking to reach their goals quicker.

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.

Okay so, I got recommended this protein by the salesman and usually I hear about GNC brand protein being bad, BUT THIS PROTEIN IS SO GOOD. I got the peanut butter puffs flavor and I love it! I make "protein ice cream" with it (ice, milk, protein powder) and it's amazing. ALSO, this protein makes good protein pancakes and waffles too (; REALLY, REALLY RECCOMEND

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.

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.
Is it safe to take while breastfeeding?
angie on Apr 18, 2018
BEST ANSWER: This is a hard question to answer. Maybe the doctor is the nest person to ask about breastfeeding and protein consumption.
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.
