Review: fantastic protein supplement - wife had a lack of protein in her blood testing, so we added this protein supplement and within one month her protein level was normal, no bowel problems, she says it is delicious and doesnt have an aftertaste and it dissolves quickly on water
Review: Great source of protein. - Great product, the taste is so well blended, the powder is easy to consume and not overly thick, it’s very convenient, doesn’t make me feel bloated. Overall the best I’ve had so far and will definitely be buying more.

## Questions & Answers

**Q: why this product wont dissolve in milk? i shake it over 30 second and i can still taste the powder so thick**
A: There’s your problem, shake for 45 seconds. You’re leaving all those reps on the table. Remember, explosive out but a controlled return. 12 shake reps should take you 45 seconds if you’re doing it right. And breath. Contract. Feel the muscles. Quit leaving those reps on the table.

**Q: does this have gluten in it**
A: Although it maybe doesn't have gluten, people with gluten sensitivities or Celiac Disease should avoid the enzyme, Casein. I have Celiac Disease and this would "kill" me!

**Q: My container did not have a scoop in it. How much powder to I use for a shake?**
A: It's approximately a 1/4 of a cup (not exactly), but I'd bet there's a scoop in the bottom of the container somewhere, they sometimes sink to the bottom of the container...  It's placed in these containers by a computer system, not a person so chances of a mistake are minimal.

**Q: Does anyone know if this is 100% Micellar?**
A: No, it has calcium caseinate as the second protein source.

### ⭐⭐⭐⭐⭐ Great source of protein.

Great product, the taste is so well blended, the powder is easy to consume and not overly thick, it’s very convenient, doesn’t make me feel bloated. Overall the best I’ve had so far and will definitely be buying more.

### ⭐⭐⭐⭐⭐ Good protein powder
*by C***E on May 14, 2026*

It’s chalky but the taste isn’t too unpleasant when blended with milk. The aftertaste is not my favorite, but if you add PB2 it really helps mask it. Keeps me super full so I resist the urge to snack as much. It hasn’t upset my stomach at all.
