    • I have tried 3 other brands, this is the best one so far
Flavor Name: Chocolate Size: 5 Pound (Pack of 1)
I have tried: -Optimum Gold Standard Whey -Body Fortress -Legion And ISOFLEX The first one I used it for quite long I tried Vanilla and Cookies and Cream it was not bad, but a fitness Coach recommended Isoflex so I tried the cocolate flavor. HIGH PROTEIN LOW CALS, DECENT PRICE I decided to try it cause it has 27g protein per ONE scoop, its prolly the highest protein per scoop while also low calorie protein powder Ive seen and at a decent price (even better w Suscribe and Save discount). TASTE Its def the best taste. I had to try Body Fortess and Legion's whey protein cause it was out of stock here for over a month. And out of the 3, Isoflex chocolate flavor tasted the better Imo. I have many diff Legions products and they are great but I def didnt like Legions whey protein in comparison w Isoflex, flavor is better and ISOFLEX texture is perfect, w Legion the powder is like pasty, it was so difficult to get a full scoop cause it would leave empty spots inside the scoop and I had to like push in the powder to fill in the whole scoop, w ISOFLEX I dnt have that problem since the powder is very loose. CONVENIENT PACKAGING To be able to just grab the scoop and easily put it and close it back its something that I didnt have w Legion. It was awful, cause it has like a ziploc shape, so its difficult to close it plus the scoop just goes inside w the powder. I ended pouring the Legion powder inside my last ISOFLEX container😂 I dont usually leave reviews but the month I spent in suffering cause I couldnt buy ISOFLEX made me realize how much I love this protein powder🥲 ... show more

    • Great Taste.
Flavor Name: Chocolate Size: 5 Pound (Pack of 1)
Been using this product for years now. I prefer Isolate over straight whey because it doesn't upset my stomach as much. Calories to protein ratio is on par with other similar brands. The chocolate has a great taste and mixes well with cold water in a simple small shaker bottle. I usually mix with other powder supplements as well and never have issues with clumping or separating. First began buying this from local supplement store years ago but pricing is considerably less here. Chocolate is the only flavor I have tried. ... show more

    • 90% protein in each serving!!!
Flavor Name: Chocolate Size: 2 Pound (Pack of 1)
Love this product. When you calculate how much protein you get from each scoop, it's totally worth the price; which is actually 90% of the protein you get. Less fillers, just exactly what you need to see actual results.
