I cannot vouch for the effectiveness of this product (or any protein supplement). It's really hard to say "PROMIX protein helped me get X, Y and Z" when there are so many other variables like diet and exercise. However, I love that this protein powder has only ONE INGREDIENT and no fillers. Interestingly, we strive to be "healthy," and in an attempt to achieve that designation or appearance, we take supplements that contain TOO MANY chemicals. My 5-star rating is based on three main factors: (1) it only has 1 ingredient, (2) it doesn't have any fancy flavor, and (3) the scoop is so small it looks like a pre-workout (not sure whether all soups with collagen contain such a protein). A downside is the price. It's insanely expensive and just not sustainable if you're drinking multiple shakes a day. If Promix could lower the price and convince people of the collagen protein benefits, it could be a real winner.
