A good meal replacement, especially post workout
I think this is a very good product. It mixes nice and easy, smells good and provides sufficient calories and macro nutrient content. You'll get a good size tub for the money which I think makes it pretty good value, although if you were going to take two shakes a day, you would find it quite expensive. I personally didn't experience any stomach issues, but this is a heavy product with a lot of ingredients so some people may find they do. Obviously an item like this is designed to be taken over a long period of time so I cannot comment on its effectiveness but used correctly it would be an excellent addition to any regimen.

Horrific taste, awful scooper!
For clarity Iโm 41 years old, Iโve been using all-in-one protein powders for around 20+ years, (PHD, USN, Maxi, SciMx). This is by far the worst tasting protein shake Iโve ever had, it has a strong chemical taste, itโs awful. Also the provider scooper is massive and awkward to use without spillage. Wonโt be looking to purchase again!

Great supplement!!
I have used this product nearly 10 years now and provides everything needed to support nutritional demands of intense training and supplements my daily protein intake nicely. The powder mixes very well however I prefer to blend mine with frozen banana, strawberries or blueberries for more nutritional benefits and tastes even more amazing!!! Try it with milk or water or half/ half depends on how thick you like it

Bad taste
It was really really bad for meโฆ I am at the gym right now and I feel nauseated and unable to continue my workout peacefully. Might be personal and every other person might not have the same body reaction to it but it was really bad for me. Unfortunately canโt get a refund
