Iso is my favorite and has been for over 10 years. Tastes great warm or cold, I like mine with milk! Mixes well. I have Chocolate on the auto-ship program. I decided to give Chocolate PB a try and was NOT disappointed. It is really close to Her. PB cups. Another favorite!.

Great for peanut butter lovers
Chocolate peanut butter is the second flavor of ISO 100 that I've tried so far and, like the cinnamon cereal flavor, it's amazing. I thought the taste of peanut butter was more prevalent than the taste of chocolate, but that's a minor quibble, especially if you like peanut butter. I appreciate getting 25g of protein out of one scoop with only 2g of carbs and not sacrificing flavor.

Chocolate Peanut Butter is better
This whey really DOES taste like a Reeses Pnut butter cup!!! It mixes pretty easily and doesn't clump. I stir it with a fork and it seems to do the trick.

Good products. Trying some different flavors.

Is this good for weight loss?

Best Answer:  Honestly to lose weight you need to eat less calories than you burn. Eating a higher protein diet keeps you satiated. This is a source of good quality protein with minimal fat and carbs. Eat a well balanced diet with a little bit of emphasis on protein and keep your calories under your caloric expenditure. That’s what it takes to lose weight. Hope this helps.

    Frequently Asked Questions

    What is hydrolyzed whey protein isolate?

    Hydrolyzed whey protein isolate (HWPI) is whey protein isolate that has been broken down into smaller chains of amino acids called peptides. Peptides are easier to digest, allowing for faster absorption into the bloodstream.

    What are BCAAs?

    Branched-chain amino acids (BCAAs) include leucine, isoleucine, and valine. They support muscle growth and reduce muscle fatigue.

    What are essential amino acids?

    Essential amino acids (EAAs) are amino acids that your body can’t produce enough of on its own, including leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. EAAs support muscle growth and recovery.
