Great taste/great recovery
Got it in a GNC pro box last week. I am a runner and I used it post 14 mile run. Legs were sore/muscle tightness immediately after the run. I combined the free sample pack with 1 cup of skim milk, 3/4 cup blueberry, and 1 cup of ice and it was amazing. Literally tasted like fruity pebbles/fruit loops. I was surprised to wake up the next day with no sore legs.

Delicious, Efficient!
Every 6 months I receive a GNC Pro Box in the mail. The box is Full of Protein, BCAA, pre workout samples plus Little Magazines.
So In the Box i received a Sample packet Of sustained Protein blend. I poured The 1 serving Protein pack into the Blender along with a couple Blue berries, plus a banana & A cup of milk.
Wow It was So Tasty! My flavor was the Fruity 1? It Tasted Exactly Like the Actual Fruity Pebbles Cereal... the flavor is Delicious! I had it in the morning and now it’s Afternoon and i have a Craving for it again hahaha
But Yes, The aminos & whey Deliver Quick muscle Fuel, and then the casein for Slow release fueling your body throughout the day.
Flavor ??
Efficiency ??
Based on the sample will i buy a Bottle? Heck yes Lol. Cant wait till pay day to buy 1

Just what I need
I am a runner who needs both the quick boost of Whey and the long burning fuel of Casean protein. The sustained product from GNC gives me just what I need.

Great Cinnamon Toast and Mixing
We switched to this protein after ProJym changed their flavors. Our favorite is the cinnamon toast; we mix it with water usually post workout and it mixes very well with a blender ball. I haven’t been taking it to gain muscle as I am female who is looking to maintain; I only use it as a supplement to my regular protein intake so I can’t vouch for the blend as far as it building.

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.
